nrf52832 ble_app_uart current consumption

[ytpark]

I am using nRF5_SDK_12.2.0, S132-SD-v3, nrf52832 pca10040 board, ble_app_uart When measuring current consumption using ble_app_uart -> 0.6~0.8mA(advertising) I want to reduce current consumption more than now. Please show me how.

ps : source -> uart_init(), printf(), buttons_leds_init() delete

If you are only concerned about saving power while advertising, you could advertise slower by changing APP_ADV_INTERVAL which is now 64 (translating to 40ms) to as much as 16383 (translating to 10.24 seconds). The more the advertising interval, the slower is the advertising rate and hence will consume less average power.

You could also save power when in connection by changing

MIN_CONN_INTERVAL
MIN_CONN_INTERVAL

to something higher, then you could save some power while in connection too. Remember that slower connection interval means slower throughput over BLE.

thank Aryan Because of the connection speed, APP_ADV_INTERVAL can not be reduced much. Is there any other way?
