STM32WB5MMGHx stops advertising after resetting from power loss.
I’m using a STM32WB5MMGHx module on a battery powered device. When the module loses power due to low battery or the battery being removed it does not advertise after regaining adequate power. Only after restarting or reflashing the wireless stack do...
STM32WB CPU2 reset
Hello, how can I call a full reset of the CPU2/BLE stack (as if the device were powered up)?I'm resetting CPU1, which then restarts the CPU2/BLE stack from some other code. But this causes some corruption with BLE notifications.
Cannot debug M0+ STM32WL55 in SBSFU Dual core project
Hi everyone, I try to debug CM0+ core (using GDB server) application LoRaWAN in SBSFU dual core project. If I only run the debugger on CM4, the program will start and run normally. But when I try to debug CM0+, it will not run and my program failed.I...
