AT commands return ERROR.

Postby jenya7 » Mon Jun 28, 2021 1:16 pm

Some of it is OK
ATE0
OK

AT+GMR
AT version:0.21.0.0
SDK version:0.9.5
OK

But most of the commands return ERROR. For example
AT+CWMODE_CUR=?
ERROR

What can be a problem?

I found some info here: https://room-15.github.io/blog/2015/03/ ... reference/

I think you have to choose a WiFi mode for the chip first, for example, client mode (1) or host mode (2)

AT+CWMODE=1
AT+CWJAP="myssid","mypassword"
