RPC with the Portenta Machine Control?

Hello, I am trying to make the M7 and M4 communicate with each other (one part of my program has big delays which I would like to circumnavigate) and am curious if anyone here has used the Remote Procedure Call (RPC) capabilities of the PMC succesfully?

I tried with this (ArduinoCore-mbed/libraries/RPC/examples/RPC_m4 at master · arduino/ArduinoCore-mbed · GitHub) example, but to no avail.
Would be nice if someone had an example sketch or could point me in the right direction.

Or if someone has other suggestions for exchanging information between the two cores that would also be appreciated!

Cheers / Einar :coffee:

Just realized I was using an outdated version of the example sketch, this post proved helpful:

Edit: Still have not managed to get it running so would still appreciate some help with the RPC on the PMC.

Edit: Got it running. RPC_M4 works just fine, had just forgotten that you need to upload to both cores :sweat_smile:
