Dear DLG support,

We are curious about how and when a battery reading in SDK 6.0.6 (default battery profile BASS implementation with cr2032 battery) is done? Is there any chance that it can happy in parallel with BLE Tx / Rx event?

The reason for this question - we have concern that if adc reading happens when Tx/Rx is happening, the overall current draw due to radio activity will be significantly higher than non Tx/RX period. If that's case, the voltage drop on battery internal impedance will be much higher hence battery reading will vary a lot depending on when it happens.

Any documentation on how and when the timer triggered events are scheduled in relation to BLE activity?

Thanks for your attention,
uta_lc
