Hi All, I hope to make a usable phone. Currently my plan is to dig into the MT6260 as started by the fernly/fernvale project. Current target is the SIM800H which contains the MT6260. I saw both that sysmocom has a $150 fernvale setup and Lime SDR has a USB bare-board for $250+ but I have to stick with something that is "phone" like and so am working on designing a small SIM800H/MT6260-based phone which can be expanded and/or used to experiment. If there was something like LimeSDR that was small and less expensive I would go that route. I imagine there will be before long. :) Meanwhile, I'd definitely like to contribute as I can to MS software/osmocom-bb. I will do what I can. Thanks,Craig github for my project... as yet it's just a "manifesto"/vapor-ware but I have a lot of half-done bits and pieces laying around... ;) https://github.com/craigcomstock/rockphone

Hi Vadim,

Fortunately, there are many SDR platforms available now. Especially interesting devices are USRP, UmTRX, bladeRF, and recently introduced LimeSDR. They can be easily programmed to support just about any type of wireless standard, of course, including some mobile telecommunication stacks. As well as for network side back-end, they can be used to perform MS side operations, excepting frequency-hopping and some phone specific features (like SIM I/O).
Btw, the first release of XTRX (http://xtrx.io) will have a SIM driver, so it'll be possible to connect it directly to a SIM card slot, as per the miniPCIe standard. If users will find this feature useful for users, it'll make it to the final release.
So, I think there is a way to bring a new live to, amazing child of the Osmocom umbrella, OsmocomBB. We can make one work on SDR hardware platforms implementing a 'bridge' between both already implemented L2/L3 and OsmoTRX.
Also note an 'ms' branch of osmo-trx. It's not a full functionality required for an MS and the code is pretty dated, but it's close enough to start.
I know that there already was some attempts (see sylvain/ms-sdr branch) to make described dreams come true, but development was stopped. And now I am going to start to work around this direction.
It was a combination of circumstances that work was not finished and I would totally support an effort to finish it.
