esp-idf-GPS-View
GPS NMEA Viewer for M5Stack
esp-idf-GPS-View
GPS NMEA Viewer for M5Stack. You can view NMEA message.
Software requirements
esp-idf v4.4/v5.x
Hardware requirements
- M5Stack
- GPS module like NEO-6M
Wireing to GPS
You can use GROVE port as UART Connection.
| GPS | M5Stack | |
|---|---|---|
| VCC | -- | GROVE(Red Line) |
| GND | -- | GROVE(Black Line) |
| TXD | -- | GROVE(Yellow Line or White Line)(*1) |
(*1) GROVE(Yellow Line) is GPIO22. GROVE(White Line) is GPIO21.
You can choice UART RXD GPIO using menuconfig.
Installation
git clone https://github.com/nopnop2002/esp-idf-GPS-View
cd esp-idf-GPS-View
idf.py set-target esp32
idf.py menuconfig
idf.py flash
Configuration
You can configure UART GPIO port / WiFi setting using menuconfig.
GPS Uart Setting
The GPS module has TX and RX, but this project uses only TX.
WiFi Setting
- For AP Mode
- For ST Mode
TCP Server Setting

Press button A(Left button) again to stop the display.
When button B(Middle button) is pressed, a single message is displayed.
When button C(Right button) is pressed, Formatted-View is displayed.
GPS Server for u-center
u-center is a very powerful NMEA message analysis tool. You can use M5Stack as u-center's GPS Server. M5Stack acts as a router. The SSID of M5Stack is 'myssid'. Connect to this access point.
When button C(Right button) is pressed sometime, Network Information is displayed.
Start u-center and connect to M5Stack. Default port is 5000.
