I received my RAK 831 ( 915 Mhz ) kit yesterday …
I was attempting to follow the Quick Start Guide, which uses the FTDI SPI USB Bridge. The guide instructs you on how to connect it to your linux box and verify the device is working over the bridge.
I was able to connect the RAK to my linux machine as documented and the program finds the unit fine. Everything worked up to the last step where you run the “test_loragw_rx” program which is supposed to test the units receive function and print out the RSSI, SNR etc.
I’m using my RN2903 which is set to 923.3 Mhz SF12 and sending some packets but the RAK never receives anything. I can see its PWR and RX lights are on, but no joy.
Has anyone used these test to verify the boards is working ? It seems like this was all set-up for 868Mhz kits…
I was hoping to verify this worked before buying the enclosure and pi board etc…
RAK831_LoRaGateway/lora_gateway/libloragw $ ./test_loragw_rx 923.3
Beginning of test for loragw_hal.c
