Wrong. What do you mean by 'device'?

I can only receive DL bursts for now.

As soon as I integrate TDMA scheduler, it will be possible
to decode raw bursts to L3 packets and forward them higher

layers.

What do you mean by 'standard stack'?

Some simple applications like ccch_scan already able

to tune SDR to required ARFCN and to start burst detection.

What for? You can tune to any of surrounding carriers, and

test the implementation against the real networks. Moreover

you can use RTL-SDR while we don't have TX capabilities.
