Bluetooth Peripheral ADVERTISE_FAILED_DATA_TOO_LARGE

Question

I am trying to advertise in NEXUS 9 and getting the error of ADVERTISE_FAILED_DATA_TOO_LARGE. It was working perfectly fine when I was adding the service after successfully

Answer 1

I suspect that this is the line of code causing the trouble:

advertiseData.setIncludeDeviceName(true);

The advertisement will not have enough space for both the device name and a 16 byte service UUID. So if you include the above then add:

advertiseData.addServiceUuid(new ParcelUuid(serviceUUID)); 

You will get the error you describe. Try removing the first line.

Answer 2

Basically your data exceeds 31 bytes, so you need to trim it down.

Change this to false, then it will work:

advertiseData.setIncludeDeviceName(false);

Answer 3

You can either change your device's name to something shorter. Example: XYZ_Name_pic - > XYZ

Go to bluetooth -> settings - > rename device name

or you can pass false instead of true

advertiseData.setIncludeDeviceName(false); // pass false not true
