Join Michael Lehman for an in-depth discussion in this video Exploring connectivity options, part of Android App Development: Internet of Things.
- We've talked about sensors.…We've talked about effectors.…Now let's talk about the kind of connectivity options…you can have in a thing…so that you can connect to it and connect to the internet.…So there's four basic kinds.…Wired TCP/IP or WiFi,…something I'm sure you're very familiar with.…Bluetooth Low Energy (BLE) which is a new kind of Bluetooth…that was just approved by the the Bluetooth SIG…in December 2013 that allows you to power devices…with very very small batteries…for very long periods of time.…Now its downside, unlike WiFi or Wired TCP/IP,…is that it's much slower and it also has a limited distance…so you have to be fairly close to the Bluetooth device…that you're connecting to.…
Cellular, you can have a thing…that actually has its own SIM card…and can send SMS, or text messages or MMS,…multimedia messages, or even make phone calls.…And finally, if you're building…a significantly custom enough thing…you can create your own RF protocol…so that only your devices can talk to each other.…But connecting up via TCP/IP you either use Wired or WiFI…
