In this chapter, we discussed the options and limitations of connecting the BeagleBone to a mobile device. We started by looking at the TCP/IP connection options versus non-TCP/IP options. The TCP/IP options can allow simple network interfaces similar to what we used for the LED flasher to work with minimal to no changes, whereas a non-TCP/IP option is likely to require, at the very least, application-level changes and possibly systemsoftware-level changes.

Then, we looked at options that require additional hardware on the BeagleBone and options that did not. We also covered Bluetooth wireless technology as a way of connecting to both Android- and iOS-based mobile devices. An important detail is that mobile devices are highly varied and connecting to different devices will most likely require multiple connection strategies.

In the next chapter, we will look at something more practical, such as recovering from mistakes. While no user would want their device to break, mistakes do happen...
