STM32WL and LoRaWAN Endnode example - resets occuring

I am new to the NUCLEO WL55JC1 and wanted to experiment with LoRaWAN.I've followed the YT series on the topic, especially the 3rd part (https://www.youtube.com/watch?v=8KNfrWoa1fw&t=26s). My End node is properly joined and connected to the things net...

Resolved! STM32WB5 transparent mode issue

Hello everyone, I am strugling with a STM32WB5MMGH that I am using with transparent mode. I am using the STM32WB5MMGH on a custom board with a STM32L4R9VIT6. The goal of the project is to use the STM32WB5 as a bridge to send data from a smartphone ap...

Enable FTD in X-CUBE-MATTER

Please tell me how to enable FTD in X-CUBE-MATTER. Is it possible to have it function as a Thread Router?

Resolved! HAL_UARTEx_ReceiveToIdle_DMA().............. IDLE event?? what is that, whatever it is is not working for me.

Hi everyone, im using an STM32WB and i just managed to get my own BLE<->UART bridge to "half work".But my problem is about UART managing.If i receive data with length of less than 247bytes(set by me) just stays in the rx bufer and no DMA transfer com...

Custom board Stm32WBA65RIV6 no DFU connection

Hello everyone, I'm writing in search of some help, as I'm not sure what else to check. I have just built a custom board controlled by an STM32WBA65RIV6, and I'm trying to connect it via DFU mode. Everything seems to be set up correctly, but the devi...

STM32WL33 µC on IAR Embedded IDE 9.30

Hello,I would like to build a project using a STM32WL33 µC on IAR Embedded Workbench IDE v9.30.1. Unfortunately, this version of IAR does not support this µC and I would like to import it but i cannot find any package suitable for IAR. Do you have an...

LoRaWAN "User defined skeleton" application stuck with `LORAMAC_HANDLER_ERROR`

I'm implementing "User defined skeleton" application. I correctly join to gateway and server chirpstack is logging 'join accept', 'join_request. When i can send some data to server i get 2 errors from library Lorawan, 'LORAMAC_HANDLER_ERROR' in funct...

Resolved! STM32WLE5 Exit stop mode 2 on EXTI or RTC timer

I cannot get STM32WLE5 (on a RAK3172 module) to exit from stop mode on either RTC timer or rising EXTI pin. I'm using STM Cube HAL functions and the stm32_lpm_if.c library. I have tried pin PB3 as either EXTI3 or as PWR_WKUP3. If I use EXTI3, I set ...
