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 any attempt to send or receive data appears to work but no data ever arrives in the input buffer.
The device I'm connecting to uses AT commands. ATI should respond with a device ID. That works fine when I run the app on my Moto Droid, but on the HTC droid, no data is ever present in the inputstream/buffer.
Personally, I'm feeling pretty sure it's a bug or limitation in this release for the HTC (because the app works great on my Moto A855 Droid).
Can anybody comment on the issue?
Obligatory code snippets:
Member variable defining my RFCOMM UUID
static final UUID UUID_RFCOMM_GENERIC = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");
Parts of my connect()
// make sure peer is defined as a valid device based on their MAC. If not then do it.
if (mBTDevice == null)
mBTDevice = mBTAdapter.getRemoteDevice(mPeerMAC);
// Make an RFCOMM binding.
try {mBTSocket = mBTDevice.createRfcommSocketToServiceRecord(UUID_RFCOMM_GENERIC);
} catch (Exception e1) {
msg ("connect(): Failed to bind to RFCOMM by UUID. msg=" + e1.getMessage());
return false;
}
msg ("connect(): Try to connect.");
try {
mBTSocket.connect();
} catch (Exception e) {
msg ("connect(): Exception thrown during connect: " + e.getMessage());
return false;
// there was a problem connecting... make a note of the particulars and move on.
}
msg ("connect(): CONNECTED!");
try {
mBTOutputStream = mBTSocket.getOutputStream();
mBTInputStream = new BufferedInputStream (mBTSocket.getInputStream(),INPUT_BUFFER_SIZE);
//msg ("Connecting non-buffered input stream...");
//mBTInputStream = mBTSocket.getInputStream();
} catch (Exception e) {
msg ("connect(): Error attaching i/o streams to socket. msg=" + e.getMessage());
return false;
}
resetErrorCounters();
setConnected(true);
return true;
}
Then I send "ATI
"
and expect something like "CAN OBD II" but I get nothing.
mBTInputStream.available(), it seems, is ALWAYS zero, even when data should be in the input buffer.
There are GOBS of trace messages being generated by the OS as viewed with adb logcat -v time
