E22-900M30S sleep current

Hello,
is there any chance to reduce sleep current to 3 uA as in datasheet? Right now when I'm using sleep function, sleep current is about 55 uA.

Regards.

Great question - to be directed at Ebyte, it's their datasheet. Personally, I don't think that value is realistic, cosidering the RF switch and PA Ebyte added. I'd start by asking them what does "Software is shutdown" mean.

So do you think that current I managed to achieve (55 uA) is as low as possible right now?

That really depends on the components Ebyte put inside the module. You can try calling sleep(false) to not retain config, but even with config retention (sleep()), the current draw of the SX126x chip (which is the only part RadioLib can control) should be 0.6 uA according to SX126x datasheet.
