Wiring:

• PiSugar3 connected to board
• GPS on serial UART (physical pins 1, 8, 9, 10)
• Radiacode 103 on micro USB

On a clean install of Raspbian 9:

• raspi-config:
  • Interfacing: Serial: Disable console, enable hardware (for gps)
  • Interfacing: Enable I2C (for PiSugar RTC)
• if prompted, restart
• install PiSugar battery management: wget https://cdn.pisugar.com/release/pisugar-power-manager.sh; bash pisugar-power-manager.sh -c release
• update PiSugar firmware: curl https://cdn.pisugar.com/release/PiSugarUpdate.sh | sudo bash
• enable PiSugar rtc by appending dtoverlay=i2c-rtc,ds3231 to /boot/firmware/config.txt
• restart
• git clone this repo into /home/pi/heliadae git clone https://github.com/sshchicago/heliadae.git
• run install.sh cd heliadae; ./install.sh

Notes

• Get PiSugar3 battery life: echo "get battery" | nc -q 127.0.0.1 8423
• Get uptime (seconds): cat /proc/uptime
• Check heliadae rc service logs: sudo journalctl -u heliadae-rc
• Stop heliadae gps service: sudo systemctl stop heliadae-gps
