+
+
+
+## Software design
+
+ After the aliyuncloud platform obtains the productkey, devicename and devicesecret, you can use aliyun suite to connect to the cloud platform. The address and port of the cloud platform are fixed. Therefore, after setting the corresponding connection information in the program, you can run the experiment.
+
+Example code:
+
+```python
+import log
+import utime
+import checkNet
+from aLiYun import aLiYun
+
+'''
+The following two global variables are required. Users can modify the values of the following two global variables according to their actual projects,
+The values of these two variables are printed before executing the user code.
+'''
+PROJECT_NAME = "QuecPython_AliYin_example"
+PROJECT_VERSION = "1.0.0"
+checknet = checkNet.CheckNetwork(PROJECT_NAME, PROJECT_VERSION)
+
+
+#Set log output level
+log.basicConfig(level=log.INFO)
+aliYun_log = log.getLogger("ALiYun")
+
+productKey = "a1llZotKkCm" #Product identification (refer to Alibaba cloud application development guidance)
+productSecret = None #Product key (this parameter is passed to none when using one machine and one password authentication. Please refer to Alibaba cloud application development guidance)
+DeviceName = "11111" #Device name (refer to Alibaba Cloud Application Development Guide)
+#Device key (use one type one secret authentication. This parameter is passed into none without pre registration. It is not supported temporarily. You need to create a device in the cloud first, and refer to Alibaba cloud application development guidance)
+DeviceSecret = "03c5e91aea167edead7d381d4b41ed71"
+
+state = 1
+
+#Callback function
+
+
+def sub_cb(topic, msg):
+ global state
+ aliYun_log.info(
+ "Subscribe Recv: Topic={},Msg={}".format(
+ topic.decode(), msg.decode()))
+ state -= 1
+
+
+if __name__ == '__main__':
+ '''
+When running this routine manually, you can remove the delay. If you change the routine file name to main.py, you need to add the delay when you want to start up and run automatically,
+Otherwise, the following poweron cannot be seen from the CDC port_ print_ Information printed in once()
+ '''
+ utime.sleep(5)
+ checknet.poweron_print_once()
+ '''
+If the user program contains network related code, wait must be executed_ network_ Connected() wait for the network to be ready (dialing succeeded);
+If it is a network independent code, you can mask the wait_ network_ connected()
+[this routine must keep the following line!]
+ '''
+ checknet.wait_network_connected()
+
+ #Create aliyun connection object
+ ali = aLiYun(productKey, productSecret, DeviceName, DeviceSecret)
+
+ #Set mqtt connection properties
+ clientID = b'11111clientID' #Custom characters (no more than 64)
+ ali.setMqtt(clientID, clean_session=False, keepAlive=300)
+
+ #Set callback function
+ ali.setCallback(sub_cb)
+ topic = '/broadcast/a1llZotKkCm/123' #Cloud customized or self owned topics
+ #Subscribe to topics
+ ali.subscribe(topic)
+ #Release news
+ ali.publish(topic, "hello world")
+ #function
+ ali.start()
+
+ while True:
+ if state:
+ pass
+ else:
+ ali.disconnect()
+ break
+```
+
+Next, you can download and verify. The Python code does not need to be compiled. You can directly download the. Py file to the module through the qpycom tool.
+
+## Download verification
+
+Download the. Py file to the module to run:
+
+
+
+After downloading, manually let the script run.

+# QuecPython accessing Huawei cloud
+
+The document mainly introduces how to use Huawei cloud. Huawei cloud device access service (iotda) is the Internet of things platform of Huawei cloud. It provides the capabilities of connecting massive devices to the cloud, two-way message communication between devices and the cloud, batch device management, remote control and monitoring, OTA upgrade, equipment linkage rules, and can flexibly transfer device data to other Huawei cloud services.
+
+The following mainly explains the mqtt connection mode of quecpthon. By reading this article, you will understand the process operation of quecpthon connecting Huawei cloud and verify the experimental theory.
+
+## Cloud settings
+
+Open Huawei cloud connection [www.huawei cloud. Com](http://www.huaweicloud.com)
+
+### Access platform
+
+Click [product] - [IOT Internet of things] - [device access to iotda] on the home page
+
+
+
+### Create product
+
+Click [product] - [create product]
+
+
+
+Select mqtt for the "protocol type" of the product
+
+
+
+### Add device
+
+Click [equipment] - [all equipment]
+
+> [https://console.huaweicloud.com/iotdm/?region=cn-north-4\#/dm-portal/device/all-device](https://console.huaweicloud.com/iotdm/?region=cn-north-4#/dm-portal/device/all-device)
+
+
+
+The [device ID] and [device key] automatically generated after registering the device are used to generate the information of the connection platform in the next step.
+
+
+
+### Generate connection information
+
+Visit [here](https://iot-tool.obs-website.cn-north-4.myhuaweicloud.com/)，填写[注册设备](https://support.huaweicloud.com/qs-iothub/iot_05_0006.html#ZH-CN_TOPIC_0251997880__li1261073102011)后生成的设备ID（DeviceId）和密钥（DeviceSecret），生成连接信息（ClientId、Username、Password）。
+
+
+
+
+
+```
+CLIENT_ID = b'5fbbb784b4ec2202e982e643_868540050954037_0_0_2021011909'
+

+```
+
+
+
+说明：
+
+For devices that do not support domain name access, execute "Ping" in the CMD command box
+"Domain name" to obtain the IP address and use the IP address to access the platform. Because the IP address is not fixed, you need to make the IP address into a configurable item.
+
+a15fbbd7ce.iot-mqtts.cn-north-4.myhuaweicloud.com
+
+1883
+
+Use the ClientID format generated by the generation tool. By default, the timestamp is not verified: device ID_ 0_ 0\_ Timestamp.
+
+-When the "hmacsha256" time stamp verification method is adopted, it will first verify whether the message time stamp is consistent with the platform time, and then judge whether the password is correct.
+
+-When "hmacsha256" does not check the timestamp, the authentication message must also have a timestamp, but it does not check whether the time is accurate, but only judge whether the password is correct.
+
+### Report data
+
+Fill in the interface address with "\ $OC / devices / {device"_ ID} / sys / properties / report ", for example," \ $OC / devices / 5e4e2e92ac-164aefa8fouquan1 / sys / properties / report ".
+

+
+\$oc/devices/5fbbb784b4ec2202e982e643_868540050954037/sys/properties/report
+
+
+
+### Distribute data
+
+The distributed data can only be requested through the API on the application side.
+
+URI
+
+Request method post
+
+URI /v5/iot/{project_id}/devices/{device_id}/messages

+
+
+## Software design
+
+After the Huawei cloud platform obtains ClientID, username and password, you can connect to the cloud platform through umqtt of quecpthon. The address and port of the cloud platform are fixed. Then you can write code experiments.
+
+Example code:
+
+```python
+from umqtt import MQTTClient
+
+CLIENT_ID = b'5fbbb784b4ec2202e982e643_868540050954037_0_0_2021011909'

+
+ state = 1
+
+def MQTT_Init():
+
+ #Create an mqtt instance
+
+ c = MQTTClient(
+
+ client_id=CLIENT_ID,
+
+ server=SERVER,
+
+ port=PORT,
+

+
+### Rule engine
+
+The rule engine is used for topic message forwarding
+
+
+
+
+
+### Filter data
+
+
+
+### Behavior operation
+
+The destination of the platform to topic message is set here
+
+
+
+Fill in the variable \ ${devicename}, set the value of devicename in the payload of publishing topic, and the message will be forwarded to the corresponding topic, such as: device a subscribes to "x3z30xabbu / 001 / data"; B device publishes "{" devicename ":" 001 "," MSG ":" test publish "}", then the destination is "x3z30xabbu / \ ${devicename} / data" = "x3z30xabbu / 001 / data"; A device receives data.
+
+### Report and distribute data
+
+Device theme format: x3z30xabbu / \ ${devicename} / data
+
+The published message content must contain "devicename": "001" before the message can be forwarded to the topic "x3z30xabbu / 001 / data".
+
+For example: {"devicename": "001", "MSG": "test publish"} "
+
+
+
+
+
+
+
+## Software design
+
+After the queicloud platform obtains the connection information, you can connect to the cloud platform in umqtt. The address and port of the cloud platform are fixed. Therefore, after setting the value of the connection information in the program, you can run the experiment.
+
+Example code:
+
+```python
+CLIENT_ID = b'X3Z30XABBU001'
+
+SERVER = b'X3Z30XABBU.iotcloud.tencentdevices.com'
+
+PORT = 1883
+
+USER = b'X3Z30XABBU001;12010126;M8STP;1647306844'
+
+PASSWORD=b'e181d0cfaf5540c8e3f173a6e88efa1f3d34db2db7a9ff845aedc67f48d9d607;hmacsha256'
+
+IMEI = None # modem.getDevImei()
+
+SUB_TOPIC = 'X3Z30XABBU/{}/data'
+
+PUB_TOPIC = SUB_TOPIC
+
+def GetDevImei():
+
+ global IMEI
+
+ # IMEI = modem.getDevImei()
+
+ IMEI= '001'
+
+ print(IMEI)
+
+state = 0
+
+def sub\_cb(topic, msg):
+
+ global state
+
+ print(
+
+ "Subscribe Recv: Topic={},Msg={}".format(
+
+ topic.decode(),
+
+ msg.decode()))
+
+ state = 1
+
+def MQTT_Init():
+
+ #Create an mqtt instance
+
+ c = MQTTClient(
+
+ client_id=CLIENT_ID,
+
+ server=SERVER,
+
+ port=PORT,
+
+ user=USER,
+
+ password=PASSWORD,
+
+ keepalive=30) #You must keep alive = 30, otherwise you can't connect
+
+ #Set message callback
+
+ c.set_callback(sub_cb)
+
+ #Establish connection
+
+ try:
+
+ c.connect()
+
+ except Exception as e:
+
+ print('!!!,e=%s' % e)
+
+ # c.connect()
+
+ #Subscribe to topics
+
+ c.subscribe(SUB_TOPIC.format(IMEI))
+
+ #Release news
+
+ Payload = '{"DeviceName":"{}","msg":"test publish"}'.format(IMEI)
+
+ c.publish(PUB_TOPIC.format(IMEI), Payload)
+
+ while True:
+
+ c.wait_msg()
+
+ if state == 1:
+
+ break
+
+ #Close connection
+
+ c.disconnect()
+
+def main():
+
+ GetDevImei()
+
+ MQTT_Init()
+
+if __name__ == "__main__":
+
+ main()
+```
+
+Next, you can download and verify. The Python code does not need to be compiled. You can directly download the. Py file to the module through the qpycom tool.
+
+## Download verification
+
+Download the. Py file to the module to run:
+
+
+
+After downloading, manually let the script run.
+
+
+

+## ** user guide for quecpthon FOTA firmware upgrade**
+
+This document introduces how to upgrade FOTA firmware based on quecpthon, and guides users to use FOTA upgrade function from the aspects of introduction of new FOTA scheme, production of upgrade package, firmware upgrade process, etc.
+
+This document applies to the following modules:
+
+- EC100Y-CN
+
+- EC600S-CN
+
+
+
+## New FOTA upgrade scheme
+
+Compared with the old scheme, the biggest advantage of the new FOTA scheme is that it can reduce the occupation of flash. Firstly, CP and DSP adopt LZMA compression with higher compression rate. Compared with the previous lzop compression, the image of CP can be reduced by 1m +, and the image of DSP can be reduced by 200 K +; Secondly, using the difference before compression, the differential packet can be smaller. Because the compression changes the file content, the difference effect is not good. The higher the compression rate, the worse the difference effect will be. Using LZMA's high compression rate algorithm, we must adopt a new FOTA upgrade scheme, which not only reduces the image, but also does not increase the differential packet. Compared with the old lzop upgrade scheme, the differential packet is smaller.
+
+## Manufacturing method of differential upgrade package
+
+The directory of upgrade package making tools is shown in the figure below.
+
+
+
+### Upgrade package production command and parameter description
+
+>The upgrade package creation commands are as follows:
+
+> adiff_2.3.exe -l [fs][fp] system_old.img system_new.img system_patch.bin
+
+- *system_ Old. Img *: represents the firmware upgrade file of the old version;
+
+- *system_ New. Img *: represents the firmware upgrade file of the new version;
+
+- *system_ Patch. Bin *: represents the generated differential upgrade file;
+
+-- L represents the location where the differential upgrade file is stored. If it is set to FS, it means that the differential file will be put into the file system; If it is set to FP, it means that the difference file will be put into FOTA_ PKG partition.
+
+The purpose of specifying the file storage location is to judge whether the backup area is sufficient at the stage of making differential subcontracting, so as to meet the old firmware backup during differential restore, which is used as a security protection test.
+
+### Upgrade package production process
+
+When making differential packages, two different versions of firmware packages are required: the old version of firmware package B (short for before) and the new version of firmware package a (short for after). The manufacturing steps are as follows:
+
+1. Copy the * system. Img * file in the firmware package to the root directory of the tool, as shown in the following figure:
+
+
+
+1. Name * system. Img * in a * systeam_ Old. Img *, and then name * system. Img * in B as
+ *systeam_ New. Img *, as shown in the figure below:
+
+
+
+1. Execute the following command:
+
+ adiff_2.3.exe -l fs system_old.img system_new.img FotaFile.bin
+
+When a and B need to upgrade each other, exchange the command to create * a respectively_ b. Bin * and * B_ a.bin*； As follows:
+
+> adiff_2.3.exe -l fs system_new.img system_old.img FotaFile.bin
+
+Similarly, you can also modify the image name.
+
+
+
+1. Complete the upgrade package of differential upgrade, and the results are shown in the figure below:
+
+
+
+## FOTA firmware upgrade process

+## ** quecpthon multithreaded development**
+
+Taking ec600s-cn as an example, this paper introduces how to use the multithreading function of quecpthon. Almost all operating systems support the concept of process, and the running tasks in the operating system generally correspond to a process. When a program runs in memory, it becomes a process. Multithreading extends the concept of multi process, so that the same process can process multiple tasks simultaneously. A thread is also called a lightweight process. A thread is the execution unit of a process. Similar to the status of process in the operating system, thread is an independent and concurrent execution flow in the program.
+
+Through this article, you will understand all the setting parameters and usage of ec600s-cn thread.
+
+### Hardware description
+
+Thread is a function realization at the software level. In terms of hardware, it only needs enough memory, which will not be repeated here.
+
+### Software design
+
+_ The thread module provides methods to create new threads and provides mutexes. The functions of each interface are described in detail below.
+
+#### Get current thread number
+
+**_thread.get_ident()**
+
+**Parameter description**
+
+nothing
+
+**Return value**
+
+If the execution is successful, the current thread number is returned;
+
+Other values indicate execution failure.
+
+#### Gets the remaining memory size of the system
+
+**_thread.get_heap_size()**
+
+**Parameter description**
+
+nothing
+
+**Return value**
+
+If the execution is successful, the remaining memory size of the system is returned;
+
+Other values indicate execution failure.
+
+#### Set the stack size used by the thread to be created
+
+**_thread.stack_size(size)**
+
+**Parameter description**
+
+|Parameter | type | description|
+| :--: | :--: | :----------------------------------------------: |
+|Size | integer | the stack size used by the thread to be created. Unit: byte; Default: 8K|
+
+**Return value**
+
+0 is returned if the execution is successful;
+
+Other values indicate execution failure.
+
+#### Create a new thread
+
+**_thread.start_new_thread(function, args)**
+
+**Parameter description**
+
+|Parameter | type | description|
+| :------: | :--: | :------------: |
+|Function | - | receive and execute function|
+|Args | - | executed function parameters|
+
+**Return value**
+
+If the creation is successful, there is no return;
+
+If the creation fails, an error is returned.
+
+#### Create a mutex object
+
+**_thread.allocate_lock()**
+
+**Parameter description**
+
+nothing
+
+**Return value**
+
+If the creation is successful, there is no return;
+
+If the creation fails, an error is returned.
+
+#### Get mutex
+
+**lock.acquire()**
+
+**Parameter description**
+
+nothing
+
+**Return value**
+
+* ture * will be returned if the acquisition is successful;
+
+* false * is returned if acquisition fails.
+
+#### Release mutex
+
+**lock.release()**
+
+**Parameter description**
+
+nothing
+
+**Return value**
+
+If the release is successful, there is no return;
+
+An error is returned if the release fails.
+
+#### Query mutex status
+
+**lock.locked()**
+
+**Parameter description**
+
+nothing
+
+**Return value**
+
+* true * is returned if the mutex is obtained by a thread;
+
+* false * is returned if the mutex is not obtained by the thread.
+
+### Interactive operation
+
+Use qpycom tool to interact with ec600s-cn, as shown in the screenshot below.
+
+```python
+>>> import _thread
+>>> _thread.get_ident()
+2126467632
+>>> _thread.get_heap_size()
+748032
+>>> lock = _thread.allocate_lock()
+>>> lock.acquire()
+True
+>>> lock.locked()
+True
+>>> lock.release()
+>>> lock.locked()
+False
+```
+
+be careful:
+
+1. import _ Thread is to let_ The thread module is visible in the current space.
+
+2. Only import_ Thread module can only be used_ Functions and variables in thread.
+
+### Download verification

+The reference code of the supporting demo is * thread in the same directory as the document_ File. Py * file. Download the. Py file to ec600s-cn and run it. The code is as follows:
+
+```python
+import _thread
+import utime
+import log
+from machine import UART
+
+#Set log output level
+log.basicConfig(level=log.INFO)
+uart_log = log.getLogger("Thread")
+
+state = 1
+msglen = 0
+count = 10
+uart = UART(UART.UART2, 115200, 8, 0, 1, 0)
+
+def uartwrite():
+ global count
+ while count:
+ write_msg = "Quectel count={}".format(count) #send data
+ uart.write(write_msg)
+ uart_log.info("write msg :{}".format(write_msg))
+ utime.sleep(1)
+ count -= 1
+ if count == 0:
+ break
+ uart_log.info("uartWrite end!")
+
+def uartread():
+ global state
+ global msglen
+ while 1:
+ utime.sleep_ms(10)
+ msgLen = uart.any() #Returns whether there is a readable data length
+ if msgLen:
+ msg = uart.read(msgLen) #Read when there is data
+ utf8_msg = msg.decode() #The initial data is the byte type (bytes), and the byte type data is converted to str
+ uart_log.info("uartread msg: {}".format(utf8_msg))
+ state = 0
+ break
+ else:
+ continue
+
+def run():
+ _thread.start_new_thread(uartread, ()) #Create a thread to listen and receive UART messages
+ _thread.start_new_thread(uartwrite, ())
+
+
+if __name__ == "__main__":
+ run()
+ while 1:
+ if state:
+ pass
+ else:
+ break
+
+```
+
+#### Hardware connection
+
+Power is supplied to ec600s-cn through type-C interface. The connection between UART and TTL to USB module is shown in the table below (for reference only):
+
+|Module UART_ Pin | TTL to USB module|
+| :------------: | :----------: |
+| Rx1 | Tx |
+| Tx1 | Rx |
+| GND | GND |
+
+The hardware connection diagram is as follows:
+
+
+
+#### Operation effect
+
+(1) Open qpycom and run * thread_ File. Py *, as shown below:
+
+
+
+(2) Since the two threads are running at the same time, UART can send data to ec600s-cn serial port while writing data (the following only indicates that reading and writing are running at the same time, but the specific log output order depends on the time of manual transmission). The following is the "quecpython" sent to ec600s-cn through TTL to USB in the third and fourth gaps of ec600s-cn writing data.
