With 9600 baud it prints "AT+GMR\r\r\n0018000902-AI03\r\n\r\nOK\r\n" and it prints garbage with 57600 and 115200 baud, which seems to be expected with this old firmware. Correct?
I tested 7 revisions of esptool back to a commit in January. As expected, no change.
The next step would be to solder my other espruino with another wifi module.
