The first element consists of four models
1. BT_MESH_MODEL_CFG_SRV
2. BT_MESH_MODEL_HEALTH_SRV
3. BT_MESH_MODEL_ID_GEN_ONOFF_SRV
4. BT_MESH_MODEL_ID_GEN_ONOFF_CLI
The second element consists of:
(for three nodes) - two vendor models
(for the fourth node) - three vendor models
The vendor models exchange periodic messages with ttl=2 and size of 45 Bytes with each other
messages period are between 10 and 30 seconds
Whenever I provision just two nodes, they work fine
After adding the third node, I receive some warnings
<wrn> bt_mesh_transport: Replay: src 0x00a3 dst 0xc001 seq 0x000e9c
<wrn> bt_mesh_transport: Ignoring old SeqAuth 0x000adb
<wrn> bt_mesh_transport: Duplicate SDU from src 0x000b
In all nodes, I receive these warnings when I add the fourth node (with the three vendor models)
<wrn> bt_mesh_net: Unable to allocate loopback
<wrn> bt_mesh_transport: No free slots for new incoming segmented messages
Afterwards, I receive the following errors
<err> bt_mesh_net: Out of relay buffers
<err> bt_mesh_transport: Out of network buffers
<err> bt_mesh_access: Failed to publish (err -105)
and I sometimes the node stops with this error : <err> os: Halting system
I made some changes to the configuration:
