They look exactly like this: , including the silkscreen text AI-Cloud Inside
I'm communicating successfully over USB serial.
The board boots, flickers blue and has steady red LED.
When it boots, it sends the following text at 115200 baud:
Ai-Thinker Technology Co. Ltd.
Every character is echoed, and LF (0x0A) causes a response (always ERROR)
CR (0x0A) is echoed, but has no other response.
AT commands are apparently not supported. Sending AT+CWLAP followed by LF resuts in
It seems that anything followed by a LF gives a response of ERROR. All other input is echoed, but gives no other response.
Is that enough to identify which module and/or firmware I have?
What firmware should I flash to get the "normal" behavior described in the many posts in the ESP8266? E.G. AT commands, and/or using the Arduino IDE to download new code, etc?
