Communication Bridge Pro

The app allows different communication technologies to talk to each other. The smartphone running it acts as a converter: it connects to remote devices that cannot communicate directly and builds a communication bridge between them, so that they can exchange data.

You can download it straight from the Play Store at this link

Hint

A practical use case is splitting the GNSS data stream to use raw data and RTK data on two channels at the same time

  • Bluetooth modules (HC-05, HC-06)
