# Connect via 900 MHz Radio

It is possible to establish a connection to rover via a serial connection with our Long Range UAV Telemetry 900 MHz radios. This method only works to connect to the rover in real-time and must be used with SpatialExplorer.

Our long range UAV telemetry 900 MHz radio communicates with rover via a serial port. The transmitters are pre-programmed to communicate via a specific baud rate.

Make sure the transmitter attached to rover is connected **PRIOR** to powering rover. During the first initial boot sequence, rover will query the long range 900 MHz radio receiver and will automatically retrieve the transmitter’s system path. This will only occur during the initial boot sequence. If the long range receiver is connected to rover after the initial boot sequence, rover will be unable to detect it.
