"Nice to meet you in this thread. Also, the info from Daniel @dl7ndr that the latest Direwolf supports IL2P. Previously, @alpha_adhito and me experimented with how to send and receive SSDV formatted image files using FM handheld to the Lapan A2 satellite (FM transponder).
We chose to use the AFSK 1K2 protocol because it’s the most feasible option. You can see the script here: a Python script to create audio for transmission and a script to decode as well. In AFSK, there is no Reed Solomon, so it really relies on RS inside SSDV. I just found out from Silversat post yesterday that there is an IL2P protocol that has a built-in Reed Solomon. With RS on I2LP fully supported by Direwolf, this is very helpful, no need to create a manual rs script anymore. It inspires me in the next time to update the file2afsk script to also support the IL2P protocol, allowing for more optimization in sending SSDV in terms of size and transmission duration time, which could be significantly shorter i guest.
i’m blessed, read and motivated from this thread, from zero knowledge about IL2P
and now have a more info about it and can decode and built the silversat script .
huray!
