Hi,

Please have a look at the Debugging an application section of the nRF Connect SDK documentation.

Hi Terje,

I also suspected that the timeout error might be originating from bt_mesh_msg_ackd_send(). As you suggested, I should do a debug session, but I'm not entirely sure how to proceed (apologies for the naive question, as I'm quite new to this). I also attempted to establish communication with one central node, one target, and one beacon, as I thought the issue could stem from multicasting a request from the client to two or more beacons, but the problem persisted.

And hope you have a wonderful Easter holiday! :)

Regards,

Matthew

Hi,

Error return value -116 is ETIMEDOUT, and most likely it comes from bt_mesh_msg_ackd_send(), called from within bt_mesh_dm_cli_measurement_start_hp(). If that is the origin of the error code, it means the message was not acked (and the send has then timed out.)

I order to figure out where exactly the node hangs, please do a debug session.

Please note that we are entering the Easter holidays, with limited capacity this week and beginning of next week.

Terje
