mesh Configuration

[MK Chen]

The relay successful rate of my Mesh setup is not 100%. I think light server miss packet from light client. I have tried to change configuration following:

1  #define BEARER_SCAN_INT_DEFAULT_MS 700 (default 2000) ;

2 #define BEARER_SCAN_WINDOW_DEFAULT_MS 700 (default 2000) ;

But it seems performance no much difference. May consult how to optimize Radio configuration in order to scan 37, 38, 39 channels fast effectively?

Thanks

Could I add one more inquiry:

how to adjust up threshold of RSSI level to filter out signal < -60 dBm ?

Thanks

Hi Chen, 

What is the success rate do you have ? 

Do you have any retransmission for a packet you send ? In our example (light_switch) we have APP_UNACK_MSG_REPEAT_COUNT  = 2 

Changing BEARER_SCAN_INT_DEFAULT_MS  and BEARER_SCAN_WINDOW_DEFAULT_MS  wouldn't help since we already scanning at 100% 

Regarding RSSI filtering, you can filter after the message arrived in access layer, but not in the radio or in network layer.

directly without relay: successful rate is 100%

one hop relay:  successful rate is 90%

two hop relay: successful rate is 50%

Could you provide more detail instruction of filtering RSSI , which file and which function ?

Thanks a lot.

repeat number what I saw using Sniffer is 3. Is it following #define?

#define PROV_BEARER_ADV_UNACKED_REPEAT_COUNT                    (4)
