Hi All,
I am testing the performance of a Relay Node in a mesh network.However it seems don't work.
I would like to show that the Relay node operation such as Rx and Re-TX message . Where is the location to indicate the operation in the code, I may add __log to debug the operation.
Thanks
Dragon
Hi Terje
Thank you for your reply, our project is based on the example Light_switch_server and we added the model onoff_switch_client to the project.
attached picture is the testing structure.
1) we limited the TX-power to -40dbm to limited the testing space.
2) the distance between the node1 and node 2 about 30cm . and the distance between the node2 and node 3 about 30cm
3) the message flow is that:
i) connected the node1( always send unicast address to the connected node)
ii) We modified the payload of the mode OnOff_server, that the payload included the target node address.
iii) App send the message ( genericOnOfftset ) to unicast address node1 , and the data of the message point to send to node 3.
iv) when the node1 (connected node) received the message, it will publish the message to node3(pointed form message)
4) we add the __Log on the code before packet_relay and in the should_relay()
#if MESH_FEATURE_RELAY_ENABLED
if (should_relay(&net_metadata))
{
__LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Relay (packet_relay) ,ttl:%d \n",net_metadata.ttl);
packet_relay(&net_metadata, p_net_payload, payload_len);
}
#endif
static bool should_relay(const network_packet_metadata_t * p_metadata)
{
/* Relay feature must be enabled */
#if EXPERIMENTAL_INSTABURST_ENABLED
if (!core_tx_instaburst_is_enabled(CORE_TX_ROLE_RELAY))
#else
if (!core_tx_adv_is_enabled(CORE_TX_ROLE_RELAY))
#endif
{
__LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "should_relay 1\n");
return false;
}
/* TTL must be 2 or greater */
if (p_metadata->ttl < 2)
{
__LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "should_relay 2:%d\n",p_metadata->ttl);
return false;
}
5) we found some case today, and we take the log on Node2 with j-link.
i) when the node1 publish to node 3. It seems work for relay node. and it will log some message when there is packet_in:
Relay (packet_relay) ,ttl:4
of Relay (packet_relay) ,ttl:8
it seems the ttl will be 4 and 8 if the relay function work.
ii) when the node3 publish to node 1. It seems don't work for relay node. and it always log the message as follow when there is packet_in
should_relay 2:1
it seems the ttl always 1.
best Regards,
Dragon
