 With the sensor and gateway nodes powered-up, you can check the RF. To do this you need a receiver for 869.5MHz. The cheapest solution is to use one of the RTL digital TV dongles with SDR Sharp software. If you have a FUNcube Dongle v1 or v2 they can also be used. Tune the receiver to 869.5MHz, set the receive mode to FM and change the bandwidth to 30kHz. If all is well, you should be seeing brief bursts of RF activity which is the transmissions from your nodes. If your using SDR software you will hear the signal just after it prints on the Raspberry Pi terminal. This is due to processing delays in the SDR software. With the sensor and gateway nodes powered-up, you can check the RF. To do this you need a receiver for 869.5MHz.
