Hi Everyone, Please help me understand what will be the average current consumption per hour with nRF52810 if I transmit 50bytes of data 4 times per hour and go to deep sleep?

Ok, I made the following assumptions:

- DCDC regulator enabled with 3V VDD

- Use crystal for low frequency clock source

- Stays connected with central device the entire time

- Connection interval set to 4 seconds and slave latency to 3. Ie, 50 bytes is transferred every 16 second.

The profiler gives an average of 2.6 uA with the above parameters, and 2.3 uA when TX paylod is zero.

Hi, Can you please double check for me and give current estimation for 50bytes at 0dBm Tx power in connection mode 4 times per hour?

Hi,

You may use our online power profiler to estimate the average current consumption for your use case. Note that deep sleep (System OFF) is not available because you will need a running timer to trigger periodic wake-up.
