Hi, Thanks for your code, it does help me a lot. I use the SX1278 + Arduino as the sender, and USRP N210 as the receiver. At the beginning, I set the parameter is: SF = 11, center freq = 434M, BW = 125k. And the transmitted message is "hello,world!"; But, I get a wrong result, as the figure 1 shows: image But when I change the SF to 8 or 10, the answer is correct. (Attention: only change SF!!!!) figure 2,3 show: image

1637201974(1) Set SF = 12 image

So, In this issue, just two things: 1: The rpp0-gr-lora also can work on SX1278+arduino and USRP N210 ( you can update the Hardware support section) 2: Can you explain why Sf = 11 or 12 can not work? Thank you very much!!!
