Re: [Discuss-gnuradio] TDMA on Gnu Radio

[Jawad Seddar]

Yes I am using only stock GNU Radio blocks.

I don't mind creating my own block for this, I just want to be sure that there is no easier way that already exists say in GRC or through a python wrapper (maybe using pmt).

Are you only using stock GNU Radio blocks?

If you have your own blocks, it's really simple: Just insert a tx_sob on
the first sample of any burst, and a tx_eob on the last.
