General question: What devices were used for testing?

[amasuke55]

Hello,

I am currently trying to use flutter_ble_peripheral with two devices: Samsung A72 and S20.
both can not seem to advertise data despite other apps like LightBlue stating that the phones should have that BLE feature.
No other app worked for testing, so I tried to use this but it also just does not advertise the data.
I have a feeling it might be the Samsung devices so it would be helpful to know what devices were used to test flutter_ble_peripheral.

I/BluetoothLeAdvertiser(15672): startAdvertising is called
I/BluetoothAdapter(15672): isLeEnabled(): ON
I/BluetoothLeAdvertiser(15672): startAdvertisingSet, calling package name = dev.steenbakker.flutter_ble_peripheral_example
I/BluetoothAdapter(15672): isLeEnabled(): ON
I/FlutterBlePeripheral(15672): onStartSuccess() mode: 2, txPOWER 1
I/BLE Peripheral state (15672): advertising
I/BluetoothLeAdvertiser(15672): stopAdvertising is called
I/BluetoothLeAdvertiser(15672): stopAdvertisingSet, calling package name = dev.steenbakker.flutter_ble_peripheral_example
V/AudioManager(15672): querySoundEffectsEnabled...
I/BluetoothLeAdvertiser(15672): stopAdvertising is called

does it appear like this in your debug console? as soon as advertising started, stop advertising is called.
tested on both Samsung A52, and Samsung S23 Ultra.... not working

feel free to contact me at [email protected] so that we can discuss this further. thank you.

For me it looks similar - like this when I try to Start advertising with the example code:

4 I/BluetoothAdapter( 9136): STATE_ON

D/BluetoothLeAdvertiser( 9136): onAdvertisingSetStarted(0, -15, 0)

I/FlutterBlePeripheral( 9136): onStartSuccess() mode: 2, txPOWER 1

I/BLE Peripheral state ( 9136): advertising

2 I/BluetoothAdapter( 9136): STATE_ON

D/BluetoothLeAdvertiser( 9136): Stop AdvertingSet

D/BluetoothLeAdvertiser( 9136): onAdvertisingSetStopped(0)```

so obviously, something is stopping the advertisement, as soon as advertisement started...

I have the same issue!

/BluetoothLeAdvertiser( 5681): Start AdvertisingSet
D/BluetoothLeAdvertiser( 5681): onAdvertisingSetStarted(1, -15, 0)
I/FlutterBlePeripheral( 5681): onStartSuccess() mode: 2, txPOWER 1
I/BLE Peripheral state ( 5681): advertising
I/BluetoothAdapter( 5681): STATE_ON
I/BluetoothAdapter( 5681): STATE_ON
D/BluetoothLeAdvertiser( 5681): Stop AdvertingSet
D/BluetoothLeAdvertiser( 5681): onAdvertisingSetStopped(1)

I resolved the issue by setting the timeout to 0.
AdvertiseSettings({
this.connectable = false,
this.timeout = 0,
this.advertiseMode = AdvertiseMode.advertiseModeLowLatency,
this.txPowerLevel = AdvertiseTxPower.advertiseTxPowerLow,
});
