[android-developers] Re: How make Bluetooth constantly discoverable
I gave up on bump a long time ago. It fails too often. There is a limit to how often I can ask the same person to bump again. After the third time, it is embarrassing how much easier it would have been to scan a physical business card.

Re: [android-developers] Re: How make Bluetooth constantly discoverable
Still an interesting concept, and P2P across different platforms is something that *should* work, there's just not a good technology available to do it (yet). ..., I guess this is why people are just using the internet as their backend. Like all things (in software?), this is something that will just take time to work.

It's not so much that t is hard, and you can vary the discovery time: http://stackoverflow.com/questions/3190623/make-bluetooth-on-android-2-1-discoverable-indefinitely The thing is though, it eats battery so you probably don't want to do it.

[android-developers] Re: How make Bluetooth constantly discoverable
All other devices? None of mine do. Nor do I want them to. As already pointed out, it is a drain on the battery. Nor is this the only problem. You can't do ANYTHING else with Bluetooth while your device is trying to do discovery. Twenty or thirty seconds should be enough. The user is doing something wrong if it takes longer than that.

Re: [android-developers] Re: How make Bluetooth constantly discoverable
I wanted to do this once. The answer is: Bluetooth probably isn't intended to be used for that thing you're trying to do. Kris (P.s., the reason people typically cite is that they want to randomly bond with other devices running their app so they can get a truly peer to peer app, but I think that this is kind of hacking BT.)
