How to debug STM32WB55 Zigbee application ?

Hello,I'm working on a project using Zigbee as main communication network.In this project we develop two devices :One as server and coordinatorOne as client and routerWe based our hardware on STM32WB5MMG.I used the examples of Zigbee_OnOff_Client_Rou...

P-NUCLEO-WB55 RF problem

I have P-NUCLEO-WB55 it worked initially well with BLE stack. Later I have ported Zigbee Stack but things were not working out. I went back and loaded the BLE stack now, but it is not even advertising with p2p sever application. I have tested the GPI...

STM32WB5MMG Zigbee Random Disconnection and reJoin not working

Hi All, I'm currently using an STM32WB5MMG module on two devices to establish a Zigbee connection between them.My project is based on the example called "BLE_Zigbee_Dyn"(one device should also be able t communicate using BLE ) implementing everything...

Zigbee stack crash on Nucleo USB dongle

Hi all,I'm trying to develop on the Nucleo USB dongle. I'm creating an empty Zigbee project with the FW 1.12.1 I configure the minimum in cubeMX the project crash in startup_stm32wb55cgux.s  I'm running FUS V1.2.0.0I'm using the wireless copro : stm3...

Can an STM32WB55 with ZigBee stack programmed, join a network of XBEE modules from Digi? I am new to WB55 though I tried upgrading firmware etc.

STM32WL SubGHz with STOP2 mode - unexpected current after first wakeup

I'm trying to get a handle on using the Sub Ghz middleware along with the processor's low power modes. I've configured an X-NUCLEO-LPM01A to power the NUCLEO-WL55JC, following the instructions from the STM32WL webinar, so I can take some measurements...

Can't get an interrupt on Pa7

I'm trying to use Pa7 for an external falling edge irq without success. I have pb1 and pb4 working as expected, but not Pa7. Is there anything special about using EXTI9_5_IRQn vector?

Once SendTxData function is called in "I-CUBE-LRWAN 2.0.0", it is called continuously.

The content of the function is simply putting data in the buffer and sending it.Even if the function is called once, it sends data 2 to 4 times.However, looking at the logs from the LORA gateway, they are sending data continuously.I'm not sure why th...

STM32WL55 does not receive uart input after a certain amount of time passes after sending RF periodically

Hi I am testing with STM32WL55I programed that MCU transmitted LoRa signal periodically and transmitted data via uart1 periodically.At first, MCU can recieve data via uart1.After a certain amount of time, MCU can't transmitted some bytes via uart1 on...

MLPF-WB55-02E3 connection to STM32WB55V WLCSP_100.

I have some questions on the response here:https://community.st.com/s/global-search/MLPF-WB55-02E3?t=1636577804470The response references MLPF-WB55-01E3 but I think it should be MLPF-WB55-02E3 for the WLCSP_100 package. Can you confirm the 65 ohm im...
