STM32WB55 and "Proper" way to send an array or struct over BLE to update characteristic.

I am working on a WTM32WB55RG BLE application that reads a sensor via I2C and sends the output of some calculations to a BLE characteristic running on the p2pserver on the same WB55RG. I'm able to successfully send an Integer to the BLE characterist...

Resolved! Cannot wakeup from STOP2 through EXTI

Hello everyone,I want to try to wakeup my system from the the STOP2 mode with a button press. The button is also in use in the rest of the application and works just fine. But when going to STOP2 it does not wake up the system again.I've tried it wit...

Error: No STM32 target found!

I think it is the most popular topic among STM32 programmers who use ST-LINK V2 programming devices.I have two devices: one is the Lora E5 MIni, and the second is the Lora E5Dev board. Both respond to the AT commands, so I expect they are healthy.A f...
