Serial communicator is able to send AT commands from Arduino Leonardo-like devices (SparkFun Pro Micro, Fio v3) to a AT command supported device (AT-09, HC-05, ESP8266, etc.). According to documentation on Arduino's website "Arduino Leonardo board uses Serial1 to communicate via TTL (5V) serial on pins 0 (RX) and 1 (TX). Serial is reserved for USB CDC communication."
- Clone git repo
- Open project in Arduino IDE
- Connect arduino-like device
- Open serial monitor
- Set bound rate to device's default
- Type supported AT command
Note: you don't need to take care about new line characters.
