We received a lot of mails stating that the flowgraph we wanted can not completed within the budget or in time.
You are right if we would request a CCSDS implementation from scratch. In fact what we were asking for is already completed for USRP and it is here: https://github.com/dcajacob/gr-ccsds
Our problem is that we could not get the example working with LimeSDR (too many frame drops). It is either us or the Osmocom blocks but we needed another one to check it. Thats why we decided to hire someone to fix it.
