Then they now have something to reference if they are stuck on the same issue :)

[quote user="fgeldenh"]Another important item is not to use the 802.15.4 source files from the SDK, but rather from the Github radio driver. They are more up to date. [/quote]

That is true, the driver is improved all the time, but with API compatibility with the latest SDKs.

[quote user="fgeldenh"]Sample makefiles would also be a great help. Could have saved me a week of head scratching.[/quote]

I think a good approach is to see how the concurrent BLE and ZigBee/Thread examples are set up with regards to the RAAL. They should have makefiles in the 'armgcc' target folder.

Hi - I have it all fully functional now. What was required was to implement the SOC Observer and then implement a Soc event handler which routes radio events to the 802.15.4 arbiter. Documentation was a bit cryptic, but if one reads it enough times it eventually dawns!

I am sure many who try to implement will be caught by this. Another important item is not to use the 802.15.4 source files from the SDK, but rather from the Github radio driver. They are more up to date. Sample makefiles would also be a great help. Could have saved me a week of head scratching.

Thank you for your help. You may close the ticket.

I suggest you check out the multiprotocol BLE and Thread examples, specifically how sdk_config.h is set up for a multiprotocol use-case.

Hi - I think I am on the track of what my issue is. I have not tied the SOC events to nrf_raal_softdevice_soc_evt_handler

I am working on that now - trying to figure out how to subscribe to soc events

I have read all of those. I am under the impression that the 802.15.4 stack handles the radio arbiter itself. I can see it calling these but it still does not work. I am using SD 6.1.1

Have you read Concurrent multiprotocol implementation using the Radio Timeslot API and Radio Timeslot API usage scenarios, and how Timeslots relates to the RAAL library? There might be something that you've missed.

What SoftDevice version are you using btw?
