I want to receive data from the serial port bluetooth device to android phone. But i don't know the UUID of that device how to find the UUID of that device?
回答1:
Extending what pwc said about the UUID being 0x1101, this is the 16 bit version of the UUID as far as I can tell. I could not work out how to instantiate an UUID with a 16 bit UUID. But as this post says you can do it by:
private static final UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805f9b34fb");
This worked for me to connect to a serial bluetooth module I bought from Deal Extreme
回答2:
If the device is using serial port profile, then yes, it is simply:
0x1101
For other pre-defined options, see the list of pre-defined UUIDs as listed in javax.bluetooth:
UUID.
回答3:
The UUID for the SPP Serial Port service is defined by the Bluetooth SIG to be 0x1101.
回答4:
Just open your device in adb shell type sdptool and browse you got your device UUID
回答5:
In the Android Bluetooth API documentation:
Create RFCOMM Socket to Service Record - UUID.
回答6:
From API level 15, you can query the supported features (UUIDs) of the remote device, use the method on the BluetoothDevice object obtained in the search:
public ParcelUuid[] getUuids ()
回答7:
you can get Device UID by simple Calling
perticulerDevice.getUuids()[0].toString()
