Problems with USART2 Rx Callback with BLE_p2pServer_ota example

Hi,i am using the BLE_p2pServer_ota example with NUCLEOWBA55 and i want transmitt a 20 Byte package over USART2 with DMA in circular mode (19200 Baud). Here as an example, i send 20 bytes every second via HTerm to USART2. BLE advertising (every 2s) i...

Resolved! BLE disconnect --> HCI_Reset unexpected behaviour

I am working on a low power mode in a freeRTOS ble application. On a user request the device is to go into low power mode Stop2. In order to achieve the lowest power consumption ~2µA (stm32wb55) the ble activity has to be deactivated and the cpu1 & c...

Resolved! Which board to choose for Nucleo WB55RG examples in CudeMX?

Moved from MPUs forum.Hi, I looking to use the Nucleo WB55RG board to prototype some BLE firmware.I was looking through the examples in Cube MX but that particular board wasn't listed but there were a few similar choices, (see below). I was thinking ...

BLE de-initiatization and reinitialization.

I am working with STM32WB55RG microcontroller. The application that I am working on needs to enter BLE mode when requested by user. I am able to start the BLE application and it starts advertising.After a set time of 1 minute the application has to c...

Generic-Switch-App: After restarting the device, button 2 cannot trigger automation

Hi,When the device is first added to Apple HomePod, pressing button 2 can trigger automation, and it is always effective no matter how many times it is triggered. But once the device restarts, pressing button 2 again is almost always ineffective. Gue...

Hello,I'm using the B-WL5M-SUB1G, using Visual Studio as my programming environment, attempting to get LoRa TX working without using the middleware.The code is below. The project serial output is below the code block. Referencing RM0453 Rev 6 (STM32W...

Detect Zigbee Network Loss

Hi,I have the problem, that my MCU seems to loose its connection to the network quite often (after some minutes or hours usually) and is therefore not usuable.I would like to detect this in my Application and then trigger either a rejoin (if possible...

STM32WB55 Low Power Mode problem (stop mode and sleep mode)

Hello, I have an STM32WB55 processor. I use BLE. I use FreeRTOS.I call the functions HAL_PWREx_EnterSTOP1Mode or HAL_PWR_EnterSLEEPMode.Before that I call the HAL_SuspendTick function.But somehow I exit WFI. Somehow an interrupt comes but I couldn't ...

Resolved! UART not working with LoRaWAN

Hi, I'm using the LoRaWAN end node example from the stm32cubewl v1.3.0. The board im using is the RAK3172 based on the stm32wle5ccu6 chip. The application i want to build reads data from a modbus using UART and sends it through lorawan. I have assign...
