Question

Any X-CUBE pack or other source code for external STM32 MCU to communicate with STM32WB in transparent mode?

Is there something similar like X-CUBE-BLE2 (which is for BlueNRG-2) for STM32WB with transparent mode firmware? We want to use STM32WB as a network coprocessor and control it with external STM32 MCU via UART. It's pretty clear what needs to be done on STM32WB side, but it's not very clear how to setup whole BLE functionality with external MCU.

Thanks for any advice.

In fact the STM32WB is already a dual core device with the M0+ being the network coprocessor of the main M4 core running the user application

You can have a look at this project below

Otherwise, the M4 core is useless in transparent mode. We have a TransparentMode project mainly used to control the RF part sending direct commands via our CubeMonitor RF tool.
