GARS HF Solar Monitor Programming How To

Install

Plug the ESP32 into a USB port, click the button, and choose its serial port. Tick “Erase device” only for a first install, because erasing also removes saved Wi-Fi and settings.

First-time set-up

1. After flashing, the GARS logo shows for 5 seconds, then the device creates a Wi-Fi network called SolarMonitor-Setup.
2. Join it from your phone or PC. If no setup page appears, browse to 192.168.4.1.
3. Choose Configure WiFi. Select your network and enter the password. Also enter your latitude and longitude (north and east are positive), and optionally your callsign for the DX page and up to 6 characters of top-line text. Then save.
4. The monitor restarts and joins your Wi-Fi. When asked, swipe a finger left to right across the screen, then top to bottom, to set up the touch screen. Settings are remembered.

Using it

• Swipe left or right to change page: Solar, Weather, Tides, Moon, Sun & Moon, Meteor showers, Equinoxes, DX spots.
• DX spots: swipe up or down to scroll, tap the top strip to change the band filter.
• Settings page: the device’s address is shown at the bottom of the solar page (for example http://192.168.1.50). Open it in a browser to change your location, callsign, top-line text, DX bands, optional tide key and to re-calibrate touch.
• Wi-Fi reset: power-cycle the board 3 times, switching it off again within 4 seconds each time.
