[GitHub] [mynewt-nimble] mohit3112 opened a new issue #868: Power consumption during non-connectable advertising
mohit3112 opened a new issue #868:
URL: https://github.com/apache/mynewt-nimble/issues/868
I am using a NRF51822 chip in DC/DC mode.
with adv interval 150ms, 0 dbm tx power ,and BLE_LP_CLOCK 1.
I am getting a current consumption of 1.2mA.
I tried changing the BLE_LL_TX_PWR_DBM to -10 but i see no impact.
Do we have any power numbers for nimble + Nrf51/Nrf52 in different modes ?

Hi @haukepetersen , thanks for those measurements!
have you improved then simce October '20?
If I play with nrf [online power estimator](https://devzone.nordicsemi.com/nordic/power/w/opp/2/online-power-profiler-for-ble), with a 200ms connectable, with 15 bytes payload, I get 58µA.
On your graph, it seems that it is the green line, at about 350µA isn't it?
I know that this estimator uses SoftDevice instead of nimble.

Floor current is most likely due to other peripherals (UART, LEDs etc) being powered
