Hi, I would like to use USART1 insted of LPUART1 on LoRaWAN_AT_Slave exmaple. But when I try to do this, I can't choose USART1 on Middleware->LORAWAN->VCOM parameter in STMCubeMX (see screenshot).I don't understand why, thus in LoRaWAN_End_Node, it i...

Hi, I would like to try nucleo-WL55 in LoRa Node with Quatz and see temperature influence in RF signal.So I have unsolder R2, and solder R39/R40. But now LoRaWAN_AT_Slave does not work anymore, even if I change TCXO to Quartz in .ioc file. I can see ...

Hi, I have new custom board on STM32WL55CCU7. I can't flash/program with STM32CubeIDE. And when i try to connect with STM32CubeProgrammer with "Normal'" mode I have this error :"Error: Cannot connect to access port 1! If you are trying to connect to ...

Hi, I trying to debug on nucleo-WL55 with serial wire debug via SWO. I have enable "Serial Wire Viewer (SWV)" in debug config, and add SWV ITM Data console (Config 0).Even add this code : int _write(int file, char *ptr, int len) { /* Implement your...

I use nucleo-WL55 board/example. STM32CubeMX Version : 6.7.0I am already in USART Asynchronous mode This problem is only when we select "AT Slave skeleton" @F.Belaid. Did you know why?

To be confirm, but you need to import this file if you want to. This file is in BSP Folder. BSP folder link to your design board/custom board or nucelo board. If you try to do a new project on nucleo board. Then you can copy and add to your new proje...

In STM32CubeIDE -> File -> New -> STM32 Project From an existing STM32CubeMX Configuration File. And you will be able to create a new project with .ioc File

It was just config of TCXO, it is not enough to change TCXO to crytal in .ioc.We need to change in "stm32wlxx_nucleo_radio.c" function "int32_t BSP_RADIO_IsTCXO(void)" by "RADIO_CONF_TCXO_NOT_SUPPORTED".And we can change switch pinout in "stm32wlxx_n...

I found the error/solution. It seem that our ESD diode on NRST was on the wrong side ! That why Hot plug, was the only one responding, and CubeProgrammer waiting for reset/read bit. Thanks for your help @JHOUD
