Hi I am testing with STM32WL55CCU6.When I use only uart1, uart1 works well.but when I use uart1 and RF(LoRa) send, MCU does not work.I coded that MCU transmit some message using uart to terminal per second.MCU continues to work fine.but I added some...
Hello,I'm a beginner on CubeIDE but I want to learn how to use the BLE from the STM32WB55 Nucleo Board. I've been following several tutorials throughout the web, from ST and others, such as https://www.youtube.com/watch?v=i10X4Blr8ns or https://www.y...
Hi, we are using stm32wb55 board for wearable project. logs on serial port are fine when we flashed simple hello world program in loop. But when flashed the application menu developed by us we are seeing some junk value all the time. we are setting t...
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...
Hi,I am using STM32L072 LoRa discovery kit and enabled UART with DMA. Some times my code gets stuck in HAL_UART_Receive_DMA( ....) function at the line SET_BIT(huart->Instance->CR3, USART_CR3_EIE);This is called at the begining of the code. It wont r...

Hello, I am transmitting a messages using UART from one STM32WL controller and I want to receive this data continuously using another STM32WL controller. I have already implemented the polling, interrupt, and DMA methods but all the time I am receivi...
Hi,I would like to refer to the P-NUCLEO-WB55 example BLE_Custom and apply it to the stm32wb30 custom board.I have succeeded in operating BLE_Custom in LPM mode on NUCLEO-WB55 by referring to the following questions.Stm32WB custom BLE example issue w...
Hello,I'm currently working on an application that integrates the LoRaWAN stack (version 2.1.0), and has to use USART2 to send/receive data. USART2 is already used by the trace utility, to send trace messages. I activated RX on interruption by callin...
Hi.I am using STM32WL55.I set USART1 with DMA tx and DMA rx.I tried to transmit some data as follows. printf("[*] Program Ver 0.2.0.0\r\n"); printf("\r\n"); printf("Net> ");"[*] Program Ver 0.2.0.0\r\n" and "\r\n" are transmitted.but "Net> " is di...
