Getting Started

Serial Connection​

The onboard USB-C and TTL UART connectors provide a simple way to both power and gain a serial connection to the RockBLOCK APNT. The serial connection use these default (non configurable) settings:

  • Baud: 115200
  • Data Bits: 8
  • Parity: None
  • Stop Bits: 1

General Operation​

Once connected, the RockBLOCK APNT will automatically start up and begin to output its NMEA Sentences at the defined frequency.

You should see output similar to this:
