Problem in Mesh network


Omar Morceli
 

Hi
There are four nodes in my bluetooth mesh network, each with two elements
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:
- BT_MESH_TX_SEG_MAX =10 
- BT_MESH_RX_SEG_MAX =10  
- BT_MESH_ADV_BUF_COUNT= 13 
- BT_MESH_SEG_BUFS=1024

However, I still get these warnings and errors?
