How do I toggle a pin upon each BLE packet.
I'm using the STM32WB55, with STM32CubeWB V1.14.1 & `stm32wb5x_BLE_Stack_full_fw.bin` V1.14.1.Looking in `app_debug.c`, I can configure `aGpioConfigList[]` and `aRfConfigList[]`, which allows for CPU2 to toggle a GPIO pin based on various events.I ca...
STM32WB55CG option bytes getting erased when debugging through STM32CubeIDE
Some strange behavior is happening when debugging our firmware through STM32CubeIDE, where it erases the option bytes upon flashing the firmware (0xFF @ 0x1FFF8000 onwards). The debugging session still launches ok and the firmware appears to be flash...
Resolved! Where to find fuota_automation.py from AN5554 document
Document AN5554 Rev4(LoRaWAN® firmware update over the air with STM32CubeW) mentions, on page 60, about file fuota_automation.py. I can not find this file in software package for STM32WL. Is this file accessible to download?
How to receive SPI data from MAX31855 with Nucleo WB55 ?
Hello, I use a Nucleo WB55 and I would like to receive temperature data from MAX31855. The protocol used is SPI. 1) ConnectionsFirstly I tested the MAX31855 with an Arduino and I managed to get data. I used the same MAX31855 and double-checked the wi...
RAK3172 Module consuming high current in stop 2 mode. How to reduce it?
I am using STM32CubeWL PingPong application. It is consuming 370uA in stop 2 mode. I need help to reduce it to 2uA(As specified in datasheet). I have initialized all unused GPIOs as analog inputs with no pull up. Still the module consumes 370uA in st...
Where can I download the version of the wireless stack v16.12.0.27
