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...

How to reduce provisioning time and error for multiple unprovision device in BLE Mesh network?

Hello ST,I am using STM32WB55 board to establish mesh network between four node. Duration of provisioning from provision node taking long time (>25 sec ) and some time my command was correct " atep prvn0 2".. even UART is showing process is complete ...
