A while ago, I picked up a Sony Smartwatch (the first one) to go with my Android phone, and I used the hell out of it. I unfortunately had to get rid of my phone, which left me with a useless smartwatch.
I'm a programmer (20 years or so of experience, so not just a hobbyist) and I figured I might be able to pair the watch with my Windows tablet's bluetooth and develop apps for it in order to squeeze out more usefulness.
No such luck, the tablet refuses to 'see' the watch and vice versa, so I suspect that the host app for Android has something to do with the pairing process, but I have no idea what.
My first hurdle is to figure out if the two are capable of pairing. I have to assume so, since they both seem to use a standard bluetooth radio (at least the phone had to). And the tablet picks up my bluetooth keyboard just fine.
Does anyone know any details about this, or know where I can find more information? No, the Sony website has no useful information. In fact, it is absolutely useless other than the scant information it has on some of the watch components, a problem I will have to deal with later (eg, it tells me the bluetooth module is 'on pin 3' which at this time tells me nothing about it). I am able to build and upload sketches to the watch using a custom toolchain a third party put together 2 years ago, but that project has apparently long since been abandoned.
I've decompiled the smartwatch app and will be reading through the code literally line by line to see if I can find anything specific to bluetooth and pairing with the watch. I suspect the app does some custom stuff behind the scenes in order to pair with the watch.
I think in the end, I will end up shopping around for a new smartwatch that the community has specifically found to be hackable, and have fun that way. Also, I ran across the Arduino while trying to get this all to work, and fell in love. I'll be getting a Mega next month to start playing with
Thanks in advance for any information.
