Hi,
I'm using the nRF51822 for a beacon and following the ble_app_beacon example (SDK 8.0.0) with some modification in order to measure the battery level through the ADC.
I'm using a CR2032 coin cell battery and reading the ADC every 40min aprox and advertising every 400ms (The battery level is included in the advertising). The problems I'm facing is that the battery only last only 2 days.
I've followed this post: devzone.nordicsemi.com/.../
to see how to reduce the consumption... but without any achievement.
You can find attached the code. ble_app_beacon.rar
Thank you in advance,
Javier
