"Automatically beacon" will turn off when you're making changes; you will have to re-enable it after you're done making changes on the setting screen. | |||
With an external radio and a phone of adequate processing power, this application can receive beacons over RF, decode them, and plot them on the map. That allows us to track balloons to figure out where they're going so we can retrieve them. | |||
The "vox delay" is a HDLC NO-OP tone that gets played before the transmitted beacon. | The "vox delay" is a HDLC NO-OP tone that gets played before the transmitted beacon. This allows a radio to be configured in VOX mode to start its transmitter after it detects noise, and still transmit the whole packet. Otherwise we would have to activate the push-to-talk (PTT) pin of the radio in order to start transmitting, and the G1 does not have easily accessible GPIO (general purpose IO) pins available | ||
