I am developing and app to Send BLE Advertisement packet in android. I have use AdvertiseData and AdverstiseSettings classes to generate the advertise packet. But when i do the StartAdvertising it always gives me an error with Error Code "2" , "ADVERTISE_FAILED_TOO_MANY_ADVERTISERS", "Failed to start advertising because no advertising instance is available."

Below is my code for MainActivity.JAVA

Could you please let me know what I am doing wrong and how can I solve this error?


From my experience there are 4 types of Android devices in regard BLE advertisement:

  1. Devices with Android pre-5.0 - LE Advertisement not supported
  2. Devices with Android 5+ that don't support LE Advertisement and return null from getBluetoothLeAdvertiser(). Those devices return false from isMultipleAdvertisementSupported(). They do this even with Bluetooth ON (see Note below).
  3. Devices with Android 5+ that return the BluetoothLeAdvertiser object, but each try of advertising ends with ADVERTISE_FAILED_TOO_MANY_ADVERTISERS error (this is the case you have). Those devices return true from isMultipleAdvertisementSupported() which as you see is not true. So far I've seen only one phone from this category: Sony xperia z1 compact, but if there is one, there are more.
  4. Devices with Android 5+ that support LE Advertisement. Those return true from isMultipleAdvertisementSupported() but ONLY when Bluetooth is ON.

Note: in the 2., 3. and 4. the BluetoothLeAdvertiser object is returned ONLY when Bluetooth is ON. Otherwise null is returned, so you actually have no clue whether the device supports LE Advertisement or not until Bluetooth is enabled.

Check the nRF Connect app: Disable Bluetooth, install the app, open and select Advertiser tab or Navigation menu -> Device information. It will ask you to turn Bluetooth ON before the status will be shown.

How to read advertisement package from ble device in android app , Migrated:. Contribute to googlearchive/android-BluetoothAdvertisements development by creating an account on GitHub. Bluetooth 5 advertising extension Android 8.0 supports Bluetooth 5, which provides broadcasting improvements and flexible data advertisement for BLE. Bluetooth 5 supports BLE Physical Layers (PHYs) that retain the reduced power consumption of Bluetooth 4.2 and let users choose increased bandwidth or range.

googlearchive/android-BluetoothAdvertisements: Migrated, The BLE Peripheral Simulator is an Android app that allows developers to try out new features of Web Bluetooth without the need for a BLE Peripheral Device. MATCH_MODE_STICKY is useful in filtering out advertising BLE devices that are too far away from the Android device, since it requires a higher threshold of signal strength and number of sightings before that BLE device is surfaced as a scan result to our app.

  • I'm currently testing on a device that does not fall in any of those types, Huawei Mate 20 lite: isMultipleAdvertisementSupported() returns false even though it does allow advertisement, but only one at a time (hence it is sort of correct, as it does not allow multiple).
  • I check for the Bluetooth LE Feature and it's available on my device. PackageManager manager = getApplicationContext().getPackageManager(); boolean featureAvailable = manager.hasSystemFeature(PackageManager.FEATURE_BLUETOOTH_LE); if(!featureAvailable) Toast.makeText(this, "Bluetooth LE feature is not available", Toast.LENGTH_SHORT).show();
  • Just the Bluetooth LE feature isn't enough. The advertisement is not supported on all devices that have Bluetooth LE. There's a list of compatible devices and you test if your device can advertise if you try out this app from Radius.
  • Actually, I am using Qualcomm eval kit for Android, APQ 8084 and it has Bluetooth 4.1, which means it supports the LE mode.
  • Did you check out the App @Markus Kauppinen suggested?
  • I checked it, but every time when click on the the Beacon Transmitter it crashes. Also, through my code I am seeing a ToastMessage of "Multiple advertisement not supported", so does it means that I am not able to transmit the beacon?
