AIS NB-IoT Library

AIS NB-IoT Library is designed to work with DEVIO NB-SHIELD I and DEVIO NB-SHIELD I Plus and connect to your own IoT Platform/Server. The library uses Software Serial for communication with the Arduino board.

For MEGA, connect GPIO8 to GPIO48 and GPIO09 to GPIO46.

Function List

General Functions

• debug(<Boolean>): Prints log on Serial Monitor if True, otherwise no log will be printed.
• setupDevice(<serverPort>): sets up the device.
• getDeviceIP(): returns the IP as a string.
• str2HexStr(< String data>): returns the string data as a hex string.
• pingIP(serverIP): returns pingRESP with values addr, ttl, and rtt.

Send Data

• sendUDPmsgStr(<serverIP>,< serverPort>,<udpData>): sends a string message with a maximum size of 512 bytes.
• sendUDPmsg (<serverIP>,< serverPort>,<udpDataHEX>): sends a hex string message with a maximum size of 512 bytes.

Receive Data

• waitResponse(): returns UDPReceive with values ip_address, port, length, data, and remaining_length.
