Hi friends:
No matter how I adjust ble_scan_cfg and ble_advertisement_cfg in wiced_bt_cfg_settings_t, the overall power consumption of mesh cannot be reduced.At present, the power consumption I have measured has been around 26ma.
Is this normal?
I'm using CYW20706.
How do adjust?
Solved! Go to Solution.

To be a good mesh citizen a node should be listening for the packets as close to 100% of the time as possible. The exception to 100% listen rule is a Low Power Node that can wake up every few seconds, minutes, hours or even days, talk to its Friend node to find out if there is queued data and go back to sleep. 26mA sounds right for 20706. 20735, 20719 and 20819 have better RX sensitivity and consume less power.

Its a good question. You are saying that you changed
.high_duty_scan_interval = 96, // High duty scan interval
.high_duty_scan_window = 96, // High duty scan window
to something like
.high_duty_scan_interval = 96, // High duty scan interval
.high_duty_scan_window = 16, // High duty scan window
and it still consumes 26mA. We can try to investigate if you are curious, but it will not work for mesh.

Thank you. I have been very confused about this question. I hope there will be new good news in the future
