Getting Jiggy With it
So, about three years ago(!) I rigged up a controller for my roller doors, and my daughter mentioned that it would be cool if I could open them using my phone.
My initial thoughts were to use a Bluetooth to serial adaptor and just use a keyboard app to send an open command.
And after getting delivery from eBay of a great HC06 module, I realised I was screwed by Apple.
No my iPhone 4 wouldn't connect to the HC06 and I wasn't going to upgrade my phone to take advantage of Bluetooth Low Energy either.
So I went searching for a solution that would work, not just on my phone, but on any mobile device. This is part of the story as to how I got there....
This will not do at all...
