ESP8266 Community Forum

- Wed Jun 15, 2016 4:00 pm #49245 Hi
I tried to get lower Baudrate (57600) _because I receive sometimes bad characters on my arduino nano from the ESP_
So I tried to lower it:
SoftwareSerial ESP8266(11, 12);
ESP8266.begin(115200);
then sending these commands in the startup
AT+RST
AT+CIOBAUD=57600

but I don't know what happen, and now it boots, tell me
"use rtc mem data ESP" at 115200 bds
then switch on another bds nearly 60000 bds but doesn't respond to any of AT commands

AT, AT+RST...
the ESP just tries to echo it (as I saw it on a logic port, than can't decode all the data because of the imprecise bds) but as I don't have a correct baud rate, I can't communicate to change it back
ESP8266.begin(57600);
or even to 115200 Bds

is there a way to reset the ESP to it default bds by connecting some GPIO to +3.3V ou 0V ?

thanks

it went on a curious bds : 74880

I also discover that, though the ESP is sending the correct answer AT CR LF OK CR LF
the Arduino is sometimes badly decoding this answer
giving OK or OE or...
any idea, even if it is not the right forum
