battery level percentage for nrf52832

[pd@learner]

I am new to nrf52832. I am using pcaboard10040 ,sdk12.3.0 and softdevice s132. I am using  battery_level_in_percent function for calculating percentage level of battery. But every time I got 100% level on nrfconnect app.But actual voltage I measured on multimeter is 2.6v

Thanks in Advance.

Hi

Take a look at this case. Also make sure that notifications are enabled, the saadc_event_handler isn't called before notification is enabled from your device:

Thanks for quick response. But  I am not using battery service. I am sending battery status in  manufacturing specific data.

Hi

Is the board connected to a USB cable as well as the battery? In that case the input voltage on the boardwill be over 3V which causes the function to always show 100% battery voltage, as the function takes values from the boards voltages and not the battery directly. 

If this does not solve your problem you have to specify what you mean by sending battery status in manufacturing specific data, as it is not clear what you do here.

Best regards,

I am just reading battery status using battery_level_in_percent and send it one of field of manufacturing specific data.

Which kind of manuf_specific_data are you referring to? Is it in a BLE service/characteristic, or in your advertising data?

Best regards,

Simon
