RaspberryPi Gateway with SX1257

[kungfupizza]

Hello, I am using a LoRaWAN concentrator based on the design of Will Whang. I have set it up using this link which uses this as packet_forwarder.

The hardware connections are properly done with RESET on GPIO25 of the Rpi and SPI host but I am getting an error as below,

I have run various tests as in the packet forwarder and results as below,

Can someone please let me know what is going wrong?

Most Likely that's a problem with: https://github.com/Lora-net/lora_gateway have a look at the issues there and you are going to see your problems all over. Typical problems / fixes:

• Concentrator does not reset properly -> Change Reset pin if wrong Pin is used and insert a delay between the pin toggle of the reset
• The SPI frequency of 8MHz is way to high. Depending on the implementation 1-2MHz seem to be the "somewhat" stable configuration
• Sometimes the raspberries can have some odd behavior in regards of their SPI configuration.

The lora_gateway has a utility to test the SPI communication. Use it until (almost) no errors occur.

Edit will127534 has git repos with already patched forwarder and gateway.
