ESP32C6 Zibbee - Minimise wake current

[peter_simons]

Hi all,

I have a ESP32C6 (DFRobot) and I have it working successfully as a zigbee end device. It consumes 54 micro amps whilst sleeping which is actually much lower than I was expecting - I'd like to know if that is expected or not.

Secondly, and more importantly, I am wondering how I could minimise the current draw when waking from sleep. I would like to have a fast poll (2 seconds) and minimise current draw. I can see it spikes to 400ma when waking from sleep, and I am wondering if there is any useful guidance to reduce those spikes in current. I'd like to know if 400ma is expected or if it should/could be even lower. When waking the device needs to poll the zigbee host and then go back to light sleep.

Thank you.
