MESH CHAT

[jermi]

Hi nordic:

    I use two NRF52DKs and download MESH CHAT separately, hoping to achieve communication between the two NRF52DKs:

   SOFT VER: NCS2.8

  The specific process is as follows: 

  NRF MESH Network Add Node, select mesh chat:

Elements Disp No elements were found；

Where did I not set it correctly？

 best regards

Hi Edvin , sorry for my late response.

1: I don't have a DK because I am using the nrf52840 with a custom PCB, with NCS v2.2.0

2: I tried with another phone (Android) and it returned the same errors, see the screenshots below:

3: Would you suggest any CONFIG_LOGS I can enable, so I can understand better where the error occurs?

    

Thank you!

Hello,

When requesting Composition Data, what Node are you connected to as GATT Proxy? On the last image from an iPhone I see that it's "PheSensor". Did you try connecting directly to the MeshChat node?

If you're using "PheSensor", are you able to send messages to this node, for example add / remove an App Key? Does this Node has proxy feature enabled? You can control it on Configuration Server screen.

I'll give few reasons why you may get a timeout for requesting Composition Data:

1. If you're connected to a freshly provisioned node - this should work. The app knows the Network key, it knows the Device Key, the Sequence Number is 0 and RPCL is empty. If it times out it means that the node ignored the receved message, i.e. failed to decode it.

2. If you're connected using a Proxy in between, there may be more reasons:

• Proxy Node does not know the Network key
• Proxy Node expects higher Seq from the phone

If you are able to send messages and get responses from a Proxy node, neither of these 2 are the reasons.

• Proxy feature is disabled on the connected proxy node

This is enabled by default in our samples.

I would try to connect to the newly provisioned node as proxy (search after tapping CONNECT (Android) or disable Auto connection and connect manually (iOS).
