Can't send using util_tx_test Plain LoRa to RF95 #119

Closed tibbis closed 5 years ago

tibbis commented 6 years ago

Hi! I don't know why I am not able to send anything from my RAK831 Gateway to my RF95 node using util_tx_test.c program as plain LoRa packets. Things I checked:

I can send from the RF95 node to the gateway using util_pkt_logger without any problems. I also tried with another Dragino-gateway that could send to the end node, so the end node is fine.

What could be wrong?

Thanks in advance!

Hey GitTibbe ! I have the exact same issue with the RAK831 LoRa Gateway. The node to node Tests have been successful(RF95<->RF95). The test_loragw_tx runs fine, but i just could not receive packets from the RAK831 gateway :(

I have tried all the config jazz that you have mentioned.

This is my Output for the following Linux command line:

sudo ./test_loragw_tx -f 433.0:433.0 -b 125 -p 23 -r 8 -z 20 -t 10 -x 3 -i

Sending 3 packets on 433000000 Hz (BW 125 kHz, SF 10, 20 bytes payload, 8 symbols preamble) at 23 dBm, with 10 ms between each Sending 3 packets on 433000000 Hz (BW 125 kHz, SF 10, 20 bytes payload, 8 symbols preamble) at 23 dBm, with 10 ms between each INFO: concentrator started, packet can be sent Sending packet number 1 ...OK OK Sending packet number 2 ...OK OK Sending packet number 3 ...OK OK Exiting LoRa concentrator TX test program root@B827EBFFFEFF8E0C:/home/pi/RAK831_LoRaGateway/lora_gateway/libloragw#

But i am unable to receive that using a RF95 module. Not even noise :(

Please Help /\

If you both have issue with the same hardware, you should contact the hardware provider.
