Relay on Subscription group address

[davidesteban13]

Hello, i am testing the mesh SDK 2.2.0 version, whit the Light switch proxy server and proxy client examples. 

I made a network whit 3 servers, those configured with the mesh addresses 0x005, 0x006, 0x007, subscribed to Mesh group address 0xC001 and publication address 0x0F01, the Client has the mesh address 0x0F01 and  publication address 0xC001.

In my tests, i put the  first node separated from the client until the max range when the messages arrives and the second and third 10 meters after but those don´t received the messages, so the messages aren't been relayed. so my question is: the messages received by the servers in the subscribed address 0xC001 are relayed or not? i am using the nrf Mesh APP and i have configured TTL=255 in each node.

Thanks for the answers.

Most likely the messages are not relayed from the first server to the next server. I would take a look at this case if I were you. I would add some logging to the handle_config_relay_set function to see if the p_pdu->relay_state is set to CONFIG_RELAY_STATESUPPORTED_ENABLED or CONFIG_RELAY_STATE_UNSUPPORTED.
