power consumption

[fanqh]

i use s110,9.0.0 , nrf51DK, and the project of "ble_app_bps"， how can i reduce consumption under the device advertising state continue.

The main things to consider in order to reduce average power consumption when advertising are:

• Avoid using LED's. The example projects use LED's extensively to indicate the state of the peripheral (advertising, connected, etc.) using the BSP.
• Use a longer advertising interval (higher value of APP_ADV_INTERVAL in the ble_app_bps project).
• Consider enabling the DC/DC. See this post for details.
• You can reduce the TX power (using sd_ble_gap_tx_power_set). However this can increase the time the peripheral must advertise before the central picks up the advertisements, so it may not be a good idea.
