Hi,
I found there's debug TTL pins on M2U. And I tried CH340 and CP2102 chip to convert serial to USB, but all failed.
I connect M2U <-> chip, GND <-> GND, RX <-> TX, TX <-> RX. And set baud rate to 115200 in Putty or TeraTerm.
With CH340, I got nothing on Putty or TeraTerm.
With CP2102, I can get some readable output from TeraTerm or Putty, but most of them are unreadable codes (see [Picture 1], [Picture 2], [Picture 3]).Maybe you guys can give me some advice or recommend me some other convert chip.
Thanks[Picture1]
