Official Observer Flasher Site
Connect your board via USB and go to https://observer.gessaman.com/ and flash your device with the necessary firmware. Follow the instructions on the page. Example config is for a heltec v3 setup as an observer/repeater with repeat off. Meaning it is only an observer.
While still connected via USB, setup observer via CLI.
