Yes - I'm talking with the osmocom folks mostly on a daily basis to try to build in support. Slowly but surely we will get there. The software is full duplex and requires the timestamps to ensure the software can recover in the case of an underflow on the transmit side.

I have had a thought of trying to fake that part out for now, just to see if I could get it working but other developments have so far stopped me.

Getting a GSM basestation solution running out of the box is extremely important to us and is our top priority after getting the software platforms stable.

That's good news then. Is there anything I can help with?
I don't really have any experience in C++. Is there any indications on how long it will take?

Thanks
Ash

Any news regarding OpenBTS? I'd be happy to test it if there already some pre version has been built...

New FPGA code has been written which is a refactoring of what was currently in there. I like it better.

We're implementing the VRT/timestamps right now. We are targeting the end of December for timestamping working completely and OpenBTS being able to use them at that same time.

Sorry for the long delay. Things should hopefully be better during the winter and with all the holidays.

Great, looking forward to this!

Will it be integrated into the normal public repo at rangenetworks, or is some special BladeRF-OpenBTS fork established?

Would the same also apply to OpenBSC? Really looking forward to this!

Many thanks

I am not awfully familiar with OpenBSC but it seems like it needs some timestamping capabilities as well. I will try to clear it up with the Osmo folks as to what they need for that, but I would imagine whatever OpenBTS needs this would be able to leverage as well.

A BSC is a parent to multiple BTSs. So, with open BSC, people can setup more complicated cellular networks.

Hello,

the board has been pretty quiet on this front recently. How is the development going?

Many thanks

More on this, and full instructions for OpenBTS in early January.
Any news?

I'm also interested in the progress of OpenBTS functionality.

Status is that it's coming along but not quite there yet.

We have the timed FPGA image checked into the main bladeRF git repository under the dev-openbts branch and with the dev-libbladeRF_sync branch, we are able to remove complexity to the RadioDevice implementation for our board. We have a preliminary amount of the transceiver written but not tested.

When we have done enough internal testing that we're comfortable with, we'll probably look to contribute back to the other project and see what works and doesn't work for them.

I don't want to push out a fork of their code to our github since that just creates a lot of confusion.

I hope that has been insightful. Sorry for the long delay in status updates.

Brian
