How to Firmware Upate
1.Make sure TE(terminal equipment) is in sta or sta+ap mode
AT+CWMODE=3
OK
2.Make sure TE got ip address
AT+CWJAP="ssid","12345678"
OK
AT+CIFSR
192.168.1.134
3.Let's update
AT+CIUPDATE
+CIPUPDATE:1 found server
+CIPUPDATE:2 connect server
+CIPUPDATE:3 got edition
+CIPUPDATE:4 start start
OK
UART to WiFi module
We can write AT firmware to this.
Use with TFT
UNO compatibles can have a pin header inside the pin socket.
If you do not use SD-CARD, you can freely use digital pins # 10 to # 13 of the TFT shield.
These pins can be used for UART communication with the ESP-01.
