GPS for Flipper Zero

A simple Flipper Zero application for NMEA 0183 serial GPS modules.

Heavy lifting (NMEA parsing) provided by minmea.

Installation

1. Navigate to the FAP Build GitHub action workflow, and select the most recent run.
2. The FAP is built for both the dev and release channels of the official firmware. Download the artifact corresponding to your firmware version.
3. Extract gps_nmea.fap from the ZIP file to apps/GPIO on your Flipper Zero SD card.

Usage

This is a single-screen app, and a few interactions are provided via the hardware buttons:

• Long press the up button to change the baud rate. The default baud rate is 9600, but 4800, 19200, 38400, 57600, and 115200 baud are also supported.
• Long press the right button to change speed units from knots to kilometers per hour.
