Decoded data not the same as transmitted data

[radio-satellites]

Hi!

I noticed that a lot of the questions are not being answered here... I hope this one will be different...

That being said, thank you for your wonderful software!

I need some help with decoding packets. I am using a custom SX1278 board with radiolib to transmit 255-byte long LoRa imagery packets. I can confirm that the right data is getting into the radio by printing the buffer out and converting it to binary (bitdump):

Here's the bitdump of the received frames (using gr-lora):

Not only are the frames obviously different, they do not decode.

Here are my settings:

To decode:

• GnuRadio LoRa realtime receive script in this repo

To transmit:

• Bandwidth 125KHz
• Spreading Factor 7
• Coding rate 4/8

I would appreciate any insight into this issue. Thank you!
