If a Bluetooth sensor doesn't already have iOS support, pairing it up will often involve a patient wait for an official app or some not-quite-official tweaking, at best -- Apple won't allow just any old unauthenticated device through the gates. Byte Works' TechBASIC 2.3 update takes those barriers down. The mobile app lets those of us with a new iPad or iPhone 4S create programs that talk to, and read from, a wide range of Bluetooth LE devices without having to write any Objective C code on a Mac. Only a TI key fob has a fully ready example program, but large swaths of devices will communicate with help from intrepid programmers -- whether they're heart rate monitors, home theater gear or seemingly anything in between. Existing TechBASIC owners can add the Bluetooth LE support through a free update; it's a relatively pricey $15 to buy the app if you're new to Byte Works' world, although it may be worthwhile to give any unused sensors a new reason for being.
