nrf5 Bluetooth Mesh: Timeout during "Requesting Composition Data..."

[clell]

I've been getting Timeouts during provisioning with "Requesting Composition Data" when provisioning via iPhone using the nRF Mesh app and nrf52840.

I've had problems getting to the root of this issue as it's happening inconsistently.  The symptoms are that it Successfully Provisions, but then times out on "Requesting Composition Data".

I've tried solutions others have suggested like increasing heap/stack with no difference.  The composition data request never seems to be received by the handle_compoistion_data_get in config_server.c when it's failing.

Mesh Version: 5.0.0

nrf Mesh on iPhone: Latest

SDK: Latest

This happens on both the light switch client and lpn examples (lpn example seems to be more often) with no changes at all to the code or settings.

It also makes no difference if I fully erase the nrf52840.

When it won't provision in the nrf Mesh app, it will provision in other iOS mesh apps without issue.

And also, when it won't provision, if I delete the nrf Mesh app completely and reinstall it, it will now provision again (sometimes)

Anyone else experience this and has a solution ?

Hi,

Can you provide the full log for when this happens?

Please can you tell me how to set logging in the iOS nRF Mesh app from the App Store.   I haven't found anything that says "Log" in the App, and when I hook up the iPhone to the console, no logs are printed from the device.  Thanks

Hi,

I am very sorry for the delay. As I do not have iOS here myself, I have asked a colleague to get the instructions for that platform.

A log from the nRF side would also provide useful information. By default the examples log to RTT. If you use Segger Embedded Studio you get the RTT log if you run a debug session. Another alternative is to use Segger RTT viewer.
