Provisioning a Chat Client

[Killianven]

Hello,

I'm trying to build a chat between mobile phone and Nordics devices.
My mobile app is developed with Flutter using the same nrf sdk as your.
For the moment i'm using a NRF52840 DK car to build and flash the chat sample.

But whenever I try to provision a device it fails without details, through your test app and mine.
(but provisioning is successful for other samples like sensor, or on-off light).

Do you have any clue why it doesn't work ?
Is the nrf mesh sdk able to provision a chat model, or only on/off servers ?

I can link my confs if needed but the errors aren't explicit.
