Hi guy,
As the title, I am trying to communicate with Thingspeak using ESP8266-01 connected via 3.3V USB-TTL adapter. And I follow this one: https://www.youtube.com/watch?v=I9O-mTSxqXc
I connect the ESP and adapter like this way:
ESP Adapter 3.3V Battery
VCC +
GND GND -
RX TX
TX RX
CH-PD +
I use serial monitor of Arduino IDE to send AT command to ESP8266-01, I can connect to my home access point, but I cannot change the value from my Thingspeak channel. Here are the commands and responses:
Note that I have a little diffrent from the Youtube Tutorial, I use the AT+CIPMUX=0 (Single TCP connection instead of AT+CIPMUX=1 for multiple connection) but this is not the problem.
