RTC_AlarmIRQHandler not working in BLE applications on STM32WB MCUs

Hello,I am having issues with RTC Alarms in BLE applications on my STM32WB boards. If BLE isn't turned on, the alarms work correctly. When I turn BLE on, the alarms stop working. After some debugging, I found out that the RTC registers are set up cor...

Lora AppKey Auto generate

Hello,I'm trying to auto generate the the AppKey on device boot using the KMS Derive.I have enabled the LORAWAN_KMS definition as described on the AN5406 and also the configuration that needed. But the device don't generate any key and after investig...

Spurious conducted emissions for TX(STM32WLE5CC6)

Hello,I have started to develop one LoRa end node around a STM32WLE5CC6 chipset(QFPN48).My device is operating in EU868 band. While the device is transmitting, I acquire the data for the frequency spectrum with a spectrum analyzer. As you can see fro...

Doubts about how to form a pre-defined Zigbee network

Hi,Currently, I'm working with the P-NucleoWB55 evaluation kit, and I'm developing a Zigbee network to exchange some messages between devices. My problem comes when I have to form and join the network. I'm not sure about the meaning of the configurat...

How do I disable Zigbee security level?

I am using STM32WB Discovery kit for STM32WBB5MM MCUs for development. I've setup the board as a RFD, Centralized End Device. How do I disable Zigbee security level if I don't need it? Currently, I have to set it manually in APP_ZIGBEE_NwkForm() by  ...

STM32WL with the LoRaWAN and the Sigfox coexistence

Hello, I would like to use the NUCLEO-WL with Sigfox and LoRaWAN in the code as proposed in the workshop (youtube video : MOOC - STM32WL workshop - 6 LoRaWAN and Sigfox coexistence). However, the zip project is not part of CubeWL. Thus, How can we up...

IEEE 802.15.4 BEACON Mode

Hello ST Community​,​I want to know if the STM32WB55RG supports MAC 802.15.4 Beacon Mode.​For now, I'm sure that the CM0+ Stack supports Only the Non Beacon Mode (SO=BO=15) and Full broadcast Mode (PANID 0xFFFF​, dest @ 0xFFFF) and OFC doesn't suppor...

Is it possible to use bare bones code in STM32WB55 and get the ZigBee working? In the examples I notice RTOS being used but I would not like to use any OS. Pointers to any documentation and/or any examples will be highly appreciated. Thanks for your time.

I am currently using 2 STM32WB55RG MCUs and they are currently running the ZigBee_OnOff example project. Unfortunately, they are not working due to this error message that I see on a HyperTerminal: "RF IF return CCA or CSMA issue!".

I'm not sure what is wrong and I have not edited the example project code. I have flashed the appropriate firmware to the MCUs as well.
