nrf52810 board low battery alarm

[mjr]

I'd like to know about the current battery capacity of the nrf52810 board.

Do you have any related documents or examples?

Thank you.

You can refer to the Saadc example that placed in SDK.

https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/nrf_dev_saadc_example.html?cp=7_1_4_6_35.

But you need to change the source to NRF_SAADC_INPUT_VDD instead of NRF_SAADC_INPUT_AIN0 in order to read out the VDD directly in case of what you used a coin-cell battery.

Thank you..!

I am currently using nus and dfus service. It works fine.
The secure DFU service is displayed in the nrfconnect app.

However, when ble_bas_enable, the duf service disappears and a battery service is created.

Is there a way to use it together?
