Hi,

The same principles still apply, use a DC/DC converter and manage the time the radio spends active.

Hi Oyvind,thanks for the reply. We use sdk version 10.0 and to use this new nrf_esb library, we need to migrate to sdk 11. At this point of time it is hard because, all our other code is based on sdk10.0 and it is almost the end of the project. So, is there a way to reduce current in the micro esb library itself? thanks

Hi,

We recommend migrating to nrf_esb, please see this blogpost. Power efficiency is achieved by spending as little time as possible in RX/TX.

The specified current draw is for the RX module, additional currents like CPU come in addition. Again, the MCU should spend as much time as possible in sleep to increase efficiency.

Best regards,

Øyvind
