1.6.1 Application Example

The G3 Modem application implements the full G3 stack and allows accessing the API through serial interface. The G3 API can be accessed at two levels:

• MAC layer (MAC wrapper). MAC serialization is implemented in stack\g3\mac\mac_wrapper\mac_wrapper.c file.
• ADP and LBP layers. ADP and LBP serialization is implemented in stack\g3\adaptation\adp_serial.c file.

The G3 Modem application interchanges data with the external device through a serial port, whose settings are:

• Baud-rate depending on the platform, see 1.6.3 Hardware Configuration
• 8 data bits
• no parity
• 1 stop bit

In the example application, the app.c file contains:

• Extended Address (EUI64) generation.
  • For PIC32CXMT it is implemented using the UniqueID.
• Non-volatile data storage. The G3 stack needs to store in non-volatile memory some counters.
  • For PIC32CXMT it is implemented using the User Signature, GPBR and SUPC power-down detection.
