I have a Samsung SM-G950F which supports BLE advertising but after a few advertisements, it starts throwing error code 2 (ADVERTISE_FAILED_TOO_MANY_ADVERTISERS) in which the android documentation says "Failed to start advertising because no advertising instance is available." and the only way to make it work again for a while is to restart the device. Another device, the HTC 10 has a similar issue, it works just fine at the start and eventually it ends up slowly missing say 1 in every ten or 20 transmissions but quickly degrades to sending say 1 in every 50. Finally, the device needs restarting to make the app work again.
My use case is as follows:
- call bluetoothLeAdvertiser.startAdvertising(...)
- Call that method for say approximately 100 times every 300ms (works just fine until a certain point)
- Then at one point the AdvertiseCallback onStartFailure(int errorCode) starts getting called and returns error code 2
- restart the phone (closing the Bluetooth and turning back or closing the app does not fix the issue)
- repeat the process
Is this an issue specifically for Samsung S8 device or am I doing something wrong with my implementation? is there a way to clear/reset the advertisers programmatically?
Also, if you are aware of any other devices with a similar issue it would be nice if you could share to help others be aware of them.
Note: the same code works just fine on my Samsung S5 SM-G900F running android 6.0.1
code snippets
public void startAdvertising() {
// making sure that the advertiser object was initialised, it is null if the user opened the app
// without having the bluetooth enable
if (bluetoothLeAdvertiser == null) {
bluetoothLeAdvertiser = bluetoothChecker.getBluetoothAdapter().getBluetoothLeAdvertiser();
// if it's still null it means the bluetooth of the device is off
if (bluetoothLeAdvertiser == null) {
bluetoothLeAdvertiserWrapperCallback.onBleAdvertiseIsNull();
return;
}
}
stopAdvertising();
bluetoothLeAdvertiser.startAdvertising(advertiseSettings, advertiseData, bleAdvertiseCallback);
}
and
public void stopAdvertising() {
isAdvertising = false;
bluetoothLeAdvertiser.stopAdvertising(bleAdvertiseCallback);
bluetoothLeAdvertiserWrapperCallback.onBleAdvertiseStoppedOrTimeout();
}
