STM32WB55 - First data sent but no one after connection to ZigBee network

‎2024-06-27 07:17 AM

Hello everyone,

I decided to write on this forum after encountering a problem with the implementation of ZigBee on my STM32WB55 microcontroller. Currently, the board connects to the network and sends the first data, but nothing happens afterwards.

I am using the LAUNCHXL-CC1352P as the RCP which is connected to my computer and I run the Zigbee2MQTT 1.37.0 process. I'm using the same configuration for the Zlinky module and everything works fine, so I assume that part of the receiver works.

As far as the FW is concerned, I would like to use the RTC to set a measurement task and send data every 30 seconds (for the moment). On the other hand, I have used some examples on ST's GitHub, in particular for the SED configuration. After some tests with LEDs, I can confirm that the RTC is working correctly.

I have the impression that each new task configuration is ignored but I don't know why and the debbug mode do not help me at all.

Thank you in advance for your help.

Here is HAL_RTC_AlarmAEventCallback(), which is triggered every second but sends data every 30 seconds :

 

 

void HAL_RTC_AlarmAEventCallback(RTC_HandleTypeDef *hrtc)
{
    // Désactivation du mode STOP pendant les mesures du capteur
    // UTIL_LPM_SetStopMode(1 << CFG_LPM_APP, UTIL_LPM_DISABLE);

    RTC_AlarmTypeDef sAlarm;
    HAL_RTC_GetAlarm(hrtc, &sAlarm, RTC_ALARM_A, FORMAT_BIN);

    if(sAlarm.AlarmTime.Seconds % 30 == 0)
    {
    	HAL_GPIO_WritePin(LED_RED_GPIO_Port, LED_RED_Pin, GPIO_PIN_RESET);
    	sAlarm.AlarmTime.Seconds = 0;
    	UTIL_SEQ_SetTask(1U << CFG_TASK_MEASURE_SENSOR, CFG_SCH_PRIO_0);
    }

	sAlarm.AlarmTime.Seconds = sAlarm.AlarmTime.Seconds + 1;


    while(HAL_RTC_SetAlarm_IT(hrtc, &sAlarm, FORMAT_BIN)!=HAL_OK){}

    // Réactivation du mode STOP après les mesures du capteur
    // UTIL_LPM_SetStopMode(1 << CFG_LPM_APP, UTIL_LPM_ENABLE);
}

Hi @Aquatwix,

First, welcome to the community.

Looking at your source code, I understand that your application configures the device as a Zigbee Sleepy end device and updates the attribute ZCL_TEMP_MEAS_ATTR_MEAS_VAL locally each 30 seconds, however, I don't see any task of sending the attribute over the air. 

API ZbZclAttrIntegerWrite is used to perform a local write attribute where the new value is updated on the application side, the client can then read this value over the air. For more details on the differences between remote and local write APIs, please have a look to this Application Note 

In your case, you can configure the Temp Meas Attribute to be reportable with a defined period, you can follow steps on these posts describing the procedure :

Post1 : Zigbee example/help on how to configure and send values 

Post2 : STM32WB55 Zigbee - Can't report value 

Please be careful using Hal_Delay() which is an active polling loop that blocks the process waiting the end of the delay, for Zigbee applications, a callback condition can be used to check the status of an over the air request. 

Kind regards,

Ouadi
