Hi

I dont know if anyone have posted anything about this, anyways:

I tried to decode the "garbage" that the esp sends when its powered on, i think its at 75000 baud - i cannot decode this stuff on my ubuntu box, properly because i have no idea how to set this baud rate. tools like stty, setserial and my favurite cu dont like this speed, just replying stuff like:




Anyone knows how to set a "special" baudrate in ubuntu?.

I am able to decode this stuff on a rigol scope, see attachment - it seems it have a lot it wants to say in its boot sequence, ive seen the words scandone and connect.

Is it possible for a standard 3v3 ftdi cable to decode this baudrate?

best regards
Kristian

Funny, thought maybe it was try to speak Chinese....

Heh yeah

I actually managed to decode the stuff with an arduino, its available here

I didnt knew it autoconnects to the previously used wifi network but thats cool

Also, its not 75000 baud, its 74880.. At least that baudrate is mentioned in their samples https://github.com/scottjgibson/esp8266 ... uart.h#L38

It's the boot loader trying to autobaud. The baud rate keeps changing where as your PC expects a constant baud. Rigol is probably capable of dealing with this.
