With very low data rates and short packets between two nRF52840s which of the following can operate at the lowest power?

1) ble peripheral to ble central uart

2) Enhanced ShockBurst (ESB) - basic protocol supporting two-way data packet communication

3) IEEE 802.15.4

4) Gazell

Thank you!

Thank you for your quick reply Edvin.  I have a few products in the market now using 802.15.4 radios and a proprietary point to point protocol.  How do you think that would stack up against a BLE solution for power consumption?

Thank you again!

[Edvin]

That depends entirely on the proprietary protocol, but as I mentioned, BLE is engineered for low power consumption, so if any, it is probably not much better than BLE. In fact, my suspicion is that BLE is more power efficient than a proprietary 802.15.4 protocol.

Best regards,

Edvin

Edvin,  I really appreciate your insights. Thank you!
