Hello, I want to use Android 2.1 to connect to an external Bluetooth device, wich is offering an SPP port to me. In this case it is an external GPS unit. When I'm trying to connect I can't connect an established socket while being in the "client" mode. Then if I try to set up a socket (being in the server role), to RECEIVE text from my P...

I have several apps which I wrote using the standard SDK. They all connect to RFCOMM devices using bluetooth, so at present, I can only support devices which are 2.0 or newer. What options are available for backporting a bluetooth app to pre-2.0 apps while re-writing as little code as possible? Thank you. ...
Yesterday we received OTA Android 2.1 on my wife's HTC Droid - HOORAY!!! I am finally able to load my carputer app on her phone. Well we loaded it, but it doesn't work. Specifically, it connects but sees no I/O!!! I paired, re-paired, and re-paired again, every time its the same problem: connect() says we connected successfully, but a...

I'm trying to open a bluetooth server socket on an Android (2.1-update1 on a GT-I5700) phone and it fails. I have run out of ideas. Some pointers on what I am missing would be welcome. Bluetooth is on, so that shouldn't be a problem. I'm also pretty sure permissions are ok: <uses-permission android:name="android.permission.BLUETOOTH">...

I've been having an issue with data integrity using an RFCOMM socket over Bluetooth in Android. I don't have any issues connecting, but the data I receive is garbled and not the same as the data that is sent. The data is sent by an RS232 device over a Bluetooth adapter, which the phone connects to. There isn't a problem with the adapter ...
