RN2903A Deep Sleep

CGW · April 15, 2021, 8:26pm

How do I put this module into deep sleep?

Deep sleep is mentioned in the documentation, but I have been unable to find how to get it working.

Issuing:

sys sleep 10000

appears to put the module into sleep with no reduction in current.

I am running firmware: RN2903 1.0.3 Aug 8 2017 15:11:09

Any help would be appreciated.

Thanks

Did you ever figure out what was causing this?

I am currently having the same problem where I issue the command:
sys sleep
but my currentl consumption is about 4-5mA still.

You might firmware updates here:

But please note that the RN2903A has other issues that were never fixed:
