Can we program esp8266 seperately using ttl converter and then integrate with arduino mega so that i can add sensors to mega and monitor through cayenne dashboard
@matrix.khan14 ,
Yes you can. Just make sure you load a compatible AT command firmware and use the ESP shield example in the library modified to whatever Mega serial port you connect the ESP to:
/*
This sketch connects to the Cayenne server using an ESP8266 WiFi module as a shield connected via a hardware serial to an Arduino.
The CayenneMQTT Library is required to run this sketch. If you have not already done so you can install it from the Arduino IDE Library Manager.
Steps:
1. Install the ESP8266SerialLibrary.zip library via the Arduino IDE (Sketch->Include Library->Add .ZIP Library) from the Cayenne extras/libraries
folder (e.g. My Documents\Arduino\libraries\CayenneMQTT\extras\libraries) to compile this example.
2. Connect the ESP8266 as a shield to your Arduino. This example uses the Serial1 hardware serial pins available on the Mega. You can also try
using a software serial, though it may be less stable.
3. Set the Cayenne authentication info to match the authentication info from the Dashboard.
4. Set the network name and password.
5. Compile and upload the sketch.
6. A temporary widget will be automatically generated in the Cayenne Dashboard. To make the widget permanent click the plus sign on the widget.
NOTE: This code requires ESP8266 firmware version 1.0.0 (AT v0.22) or later.
