Wio E5 Mini : Built-in AT command firmware

I understand that the Wio E5 mini module comes with a built-in AT command firmware, is there a source code for that firmware so I can use it again in the future? I looked in the GitHub page for the firmware but I was not able to find it.

Any help would be appreciated, Thank you.

regards,
Ab

Hi there,

The Wio-E5’s factory AT firmware does not currently support reverting after an erase, and Seeed does not provide a source or binary version of this firmware.
