My STRKT01 doesn't connect with my network.

In my condition, I have to use the AU915 frequencies due to the rules of my localization. So, I changed the frequency in the compiler and in the firmware I updated the connection mode to ABP, because I've been working with LoRa and for me always work...

Is there a example of use STM32WB55 Nucleo Pack boards as USB-BLE-USB bridge?

I want to build USB-BLE bridge using nucleo board - something like virtual serial connection between boards. I want to connect both boards using Bluetooth interface. Then USB dongle should forward data from USB CDC to Nucleo board and vice-versa fro...

Resolved! ZbZclOnOffServerAlloc Missing reference

Hi,I finally got my zigbee up and running on v.13.xx but it stops working, properly in M0 core after 5-20seconds.However I thought it would be good to go to 14.1, so i did, made a project.But i cannot compile the project.It is based on Cube...I get t...
