I doubt, they make their own chipset -- it may be possible to flush > the same firmware into a much cheaper dongle with the same chipset... hmm... i don't see it. sorry. may be i'm looking in the wrong place. so, yes, they have custom firmware that is flashed onto ubertooth-zero or ubertooth-one dongle. my understanding is that those are not off-the-shelf dongles. https://www.sparkfun.com/products/10573 is $120 (ubertooth-one) https://www.amazon.com/Great-Scott-Gadgets-WRL-10573-Ubertooth/dp/B007R9UPHA (Amazon) yes, they are not making completely custom chip, they are reusing some off-the-shelf components. however, final board it custom. in fact, i'm not even 100% sure that ubertooth-one is a complete bluetooth dongle. according to schematics they use CC2400 Single-Chip 2.4 GHz ISM Band Transceiver and CC2591 2.4 GHz Range Extender strapped to LPC175x ARM Cortex-M3 microcontroller. it may be just designed for the purpose of scanning and may be injecting packets. there are references to a modded CSR firmware that can be flashed onto off-the-shelf CSR dongle. however, even with modded firmware, it will not act as full scanner. according to the posts it will sniff traffic for known BD_ADDR. as far as porting it, i don't see what's the big deal. it seems like it should be possible to port this. thanks! max
