Resolved! X-CUBE-EEPROM adding zeros randomly to current page
Dear ST members,My application is using the EEPROM emulated library (X-CUBE-EEPROM) with an STM32WB microcontroller. I noticed that, when I update a variable, the page can be padded with random zeros. Attached are screenshots of the page before and a...
STM32WB55 is not scanning using the whitelisting
According to BLE spec, whitelisting is not related to paired or bonded devices. Our application uses the advertisement and scanning for sensor beaconing application. STM32WB55 is not able to scan the interested sensors by whitelisting. STM32WB is not...
P-NUCLEO-LRWAN3 End node AT command terminal communication
I just flashed the end node of the P nucleo LRWAN 3 with the AT master firmware, but I am still unable to send AT commands via my terminal to reconfigure some parameters of the end node. I also made sure I set up all the necessary parameters in the t...
NUCLEO-WL55JC2 RF example – simple Tx/Rx reference needed
Hello, Board: NUCLEO-WL55JC2 (2 boards)MCU: STM32WL55JCIDE: STM32CubeIDEProgramming: Bare-metal C or Cube IDE(C/C++) Goal:I want a minimal RF example using two NUCLEO-WL55JC2 boards where one board transmits a simple message and the other receives it...
STM32WL disable LmHandlerJoin at startup
Hi, I'm using a STM32WL5MOC. I see that in the LoRaWAN_Init the LmHandlerJoin is not in a USER CODE section, meaning that it can't be disabled. In my application I would like to do the join upon my request and not in the init. How I can prevent from...
