Hello,
I am trying to comunicate the STM32U5 of the board with the STM32WB module, as I need a star network (1 client with 5 servers), I could also use a mesh. To comunicate different nodes.
I am having trouble with it, as I just send basic "AT+BLE_RST=1" and I never get any response.
I have flashed the STM32WB with FUS and BLE stack using STM32CubeProgrammer wireless tab and then the BLE_AT_Server module application as noted here: https://github.com/STMicroelectronics/STM32CubeU5/tree/main/Projects/B-U585I-IOT02A/Applications/BLE/BLE_AT_Client
In the U5 I set the UART4 TX as blocking:
HAL_UART_Transmit(UARTx, buffer, length, 1000) != HAL_OK)And RX with DMA:
__HAL_UART_ENABLE_IT(UARTx, UART_IT_IDLE);
HAL_UART_Receive_DMA(UARTx, stm32wb_rx_buffer, stm32wb_rx_buffer_size);
And expecting to get the answer on:
void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart)
I have previous experience on doing this with H7s, F4s, L4s, but I do not know if is a problem with the GPDMA or what, here is the config:
DMA Channel 11 is used.
I also tryed setting the WAKE_UP Pin of the module High and Low with no luck.
Hope someone can give me any advice.
Thank you!
