nRF5232 consuming too much power with BLE advertising interval 2 secs.

[AN Malik]

nRF5232 consuming too much power with BLE advertising interval 2 secs. I had tried using MbedOS6/OS5 and as well sleep_mode: deep sleep. Can anyone help, my appplication is using battery GATT service and also digital IO, nothing else. I have noted current consumption is nearly 5mA however documented in xuA.
Thank you.

Hi,

You need to provide information about your hardware setup. Is this a custom board or a development kit?

I would start with putting the chip to system OFF mode,

NRF_POWER->SYSTEMOFF = 1;

then you will know the base current. If there are any other components on the board that consume current, measurement error etc.

In general we do not support MbedOS.  I do not know if it's power optimized or not. I would recommend using the nRF5 SDK, or nRF Connect SDK instead.

Start out with the ble_app_pwr_profiling application in the nRF5 SDK. You can flash the pre-compiled hex in the SDK directly, and measure current.
