I am trying to decode S2LP transmission using software defined radio. I am able to transmit between S2LP devices but the message is not being decoded by my SDR. Any help from anyone with experience would be great.

The software I am using is SDR# and soundmodem.

Hello,

You need a plugin to decode your modulation, i couldn't find one

I used a GNU radio flowchart and was able to decode the messages sent.
