MWU event to interrupt

Unfortunately, this is correct. The MWU can't be used by the application when SoftDevice is enabled. You could use the Cortex M4's MPU, through the MPU driver, but that would generate an exception if the area is accessed, which I believe is not what you want.

I'm not aware of any other ways to get interrupted on RTT data, since RTT is just a RAM buffer.

Yeah, Im using also BLE. I just saw the MWU is not compatible with SoftDevice. So no solution for my problem.

Is there any other way to get received Segger RTT data via interrupt?

Hi,

The MWU have interrupt support, see list of main features in peripheral documentation:

Programmable maskable or non-maskable (NMI) interrupt on events

Which APIs are you using to configure the MWU?

Which SDK version are you using?

Are you using BLE/SoftDevice in your application?

Best regards,
Jørgen
