ESP8266 12E WangTongze Arduino Shield (moer)

[iura]

Hi everyone!

Please pardon me if there is a topic here about 12E but I didn't found it.



I have uploaded esp8266-20200911-v1.13 firmware using ESP download tool ver 2.4. Now I am trying to connect to the shield using com-port via USB to TTL convertor. I have tried 9600 and 115200 baud with no flow control, but still useless. Just getting some weird symbols at connect and no response.

When I am using Thonny it writes:

Code: Select all

Device is busy or does not respond. Your options:

  - wait until it completes current work;
  - use Ctrl+C to interrupt current work;
  - use Stop/Restart to interrupt more and enter REPL.

At REPL command I get:

Code: Select all

REPL
