How to pass data between two cores (STM32WB55)

[kcire L.]

Hi,

I have a program running on the M4 core of the STM32WB55 and would like to pass a data buffer to the M0 for transmission over BLE (notification). I'm having a really hard time understanding how to pass the data between the cores and was hoping for a simple example that would outline the best way to do this.

Any help is very much appreciated.

Thanks in advance.

Hello,

You can find BLE examples in STM32CubeWB package available here:

Exchanges between M4 and M0 cores are done through SHCI commands.
