Branches – OsmocomBB
Using this branch you can dump the burst sequences (even encrypted) from the network. It is possible through the Sylvain's DSP patch which forwards the raw bursts to host apps without any processing from its side. Note that isn't hacking tool and is only meant as a quick tech demo. See Sniffing. This branch provides a menu application which allows you to choose and run one application of several others stored on flash. For details, see Flashing tutorial. This is not a real IMSI Catcher as you might think...
multi-voltage USB UART board released - multi-voltage USB UART - Open Source Mobile Communications
But for ever more and more unusual voltages I always had to build a custom cable or a custom. In 2016, I finally couldn't resist any longer and built a multi-voltage USB UART adapter. This board exposes two UARTs at a user-selectable voltage of 1.8, 2.3, 2.5, 2.8, 3.0 or 3.3V. It can also use whatever other logic voltage between 1.8 and 3.3V, if it can source a reference. Rather than just building one for myself, I released the design as open hardware under CC-BY-SA. For more information see mv-uart.
