Programming and Reflashing the ESP8266 ESP-01
– Instructions tested on April 2017, may be outdated! - The following instructions require technical skills and assume that you are using my LELESP dev board (or a similar one) –
I connected the module to my PC through the FTDI cable. At this point, I wanted to start talking to the ESP. For that, a terminal emulator like picocom or the standard screen command will do the job. First, your board might talk at any of several baud rates. The ones to try first are 9600 and 115200 (it depends on the version of the firmware running onboard).
