Module stopped responding #472

Closed marcosasilvalepe closed 3 years ago

marcosasilvalepe commented 3 years ago

Hi!, I was programming the module when all of a sudden I it stopped responding and now I can't do anything with it.

I tried flashing another firmware to try and reset it but I keep getting CHST_Read32 error from coolwatcher. The cable connections are correct but I keep getting that error and I can't use the module at all.

Is there any way to fix this ?

UPDATE:

Fixed this by flashing the Factory AT command binary from https://docs.ai-thinker.com/en/gprs/firmware

with this tool https://docs.ai-thinker.com/_media/gprs/ai-thinker_a9_a9g_at_v02.02.20190915r.rar

Thanks to @lamqhoang for the info.
