I am using a concentrator board based on Semtech SX1301 along with a Raspberry. My goal is to use it as a gateway to receive packet from nodes. These nodes are esp32 boards connected with a SX1276 LoRa radio.
For while I am just trying to test the communication between one node and the concentrator. So I found a whole library who implements the HAL (Hardware Abstraction Layer) and also has also some utilities like “tx test, packet logger”, these utilities are pre compiled programs to test a transmission or a reception for example.
This is the link for all this: https://github.com/Lora-net/lora_gateway
When I tried to run util_packet_logger on the concentrator, I ran also a code sending a constant byte in loop on my node.
The result was the followings:
The logger file in the concentrator did catched packets and if I turn off the node it stops logging. This is a proof that the GTW is receiving something.
The logger file has a topic “payload” that was full of non sense bytes. The Byte I sent was not there. I think it was garbage.
I am just starting with LoRa and it all, does someon could give me a hint about what is happening?
