# 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
This project can be used as a GPS Server for u-center.
# Operation
When button A(Left button) is pressed, the display starts.
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](https://www.u-blox.com/en/product/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.
