Cayenne ESP8266 Shield WiFi Example | |
Adapted from Blynk's ESP8266_Shield_HardSer Example | |
This sketch connects to the Cayenne server using an ESP8266 WiFi module as a shield connected | |
via a hardware serial to an Arduino. | |
You should install the ESP8266HardwareSerial.zip library via the Arduino IDE (Sketch->Include Library->Add .ZIP Library) | |
from the Cayenne extras/libraries folder (e.g. My Documents\Arduino\libraries\Cayenne\extras\libraries) to compile this example. | |
NOTE: Ensure a stable serial connection to ESP8266! | |
Firmware version 1.0.0 (AT v0.22) or later is needed. | |
You can change ESP baud rate. Connect to AT console and call: | |
AT+UART_DEF=115200,8,1,0,0 | |
For Cayenne Dashboard widgets using digital or analog pins this sketch will automatically | |
send data on those pins to the Cayenne server. If the widgets use Virtual Channels, data | |
should be sent to those channels using virtualWrites. Examples for sending and receiving | |
Virtual Channel data are under the Basics folder. | |
