Installation
Necessary Software
Necessary Hardware
- Computer (I used a Raspberry Pi Zero 2 W)
- ESP8266
- uBlox 6m GPS module
- External Power Supply
Setup
Serverside
Compile the recipient Golang program on the computer with
go build gps.go
Nodeside
Open the sketch and user the Arduino IDE to upload to the ESP module Connect the GPS module; pinout is given in Arduino sketch, must check against pinout image
Running
Serverside
Run the recipient with
./gps &
When the path is received, it will be stored in a file named with the received date. It can be viewed with
cat YYYYMMDD.path
Nodeside
Compile and download the sketch to the ESP
Usage
Connect the ESP and GPS to the external battery. Once the GPS warms up, it will get a location reading every 2 seconds. Power does not need to be continuously supplied, as the location is written to the EEPROM. To get the location data, reset/power cycle ESP.
