Task :
1 To establish the communication between PIC24F with QuectelEC20 LTE modem, and sending data to web server.

Used protocols : From USER –MCU using RS485,MODBUS, and From MCU -EC20 using I2C Protocol.

Listed of Functions;
1.Read/Write data from user to MCU
2.Read/Write data from MCU to EC20, and push data to webserver.
3.To enable all the feature in EC20 Like (Network status, Net Mode, sleepmode,signal strength, etc.)
4.It support for all the sim cards

Description :
1.Read data from user to MCU using protocol RS485, MODBUS, the lengtof data 16 bit. And to transfer the data to webserver through EC20. And also MCU to receive data from EC20.
2.Each functions must be in separate libraries.
3.Firmware development Using MPLAB X IDE
