Hi Craig, good to hear that you're working on something as exciting as MTK support of OsmocomBB.

I would strongly encourage you not to spend time in designing more hardware rather than working on the software side of things. Understanding the DSP/ARM interface of mediatek baesband chips is the primary key into creating a L1 adaptation of OsmocomBB that works on such hardware. > If there was something like LimeSDR that was small and less expensive I would > go that route. I imagine there will be before long. :) I don't think a General Purpose SDR solution will lead to a usable phone. The GP SDR is too large and power hungry to begin with, and then you need a host processor that can do all the signal processing, and you're suddenly talking more about an embedded PC rather than a battery powered phone. > Meanwhile, I'd definitely like to contribute as I can to MS software/ > osmocom-bb. I will do what I can. Pleaes do so. I'm happy to review and give feedback. -- - Harald Welte <lafo...@gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
