Unable to pair Bluetooth Smart Lights

[a1y1ng]

I compiled and run successfully the source code from github at https://github.com/tuya/tuya-home-andro ... ample-java. However, I could not pair the Bluetooth Smart Lights with the following product parameters:
Base: E27 E26 B22
RGB: 2700K-6500K

When I tried Bluetooth scanning, specifically from these lines:
ThingHomeSdk.getBleOperator().startLeScan(scanSetting, bean -> {
Log.d(TAG, "扫描结果:" + bean.getUuid());
scanDeviceBeanList.add(bean);
getDeviceInfo(bean);
});

It doesn't print out anything though the debug mode is turned on with ThingHomeSdk.setDebugMode(true).
May I know if I need to set any configuration in Tuya development platform? Or do I have to activate official edition in order to do device pairing?

Bluetooth scanning requires necessary permissions. You can refer to the guidance document to determine whether the necessary permissions have been granted.

see:
https://developer.tuya.com/en/docs/app- ... v7r2ju4c21

Another situation is that even if all the permissions have been granted, the device needs to be in the state of activation before it appears in the callback, and the callback returns nearby devices in the activation state.

Based on the log, the bluetooth scan is enabled. Please take a look:

Based on the log, can you find the root cause?

And also, I can actually add the light bulb using official tuya app. So I'm not sure if the source code in tuya-home-android-sdk-sample-java is really working.

[hackill]

If the tuya app works, it indicates that the device is working properly.

There was no error detected in the logcat output. I'm now checking if the demo code is working as intended.

[hackill]

I checked the code in the demo and ran it again, and it works normally. Looking at the log you provided, it can be seen that the scan has worked. Then you can assist with other operations.

1. The targetSdkVersion of the demo is lower than 31, and the demo is not compatible with android 12.

2. Install the Bluetooth debugging tool nrf-connect, use this tool to see if your light bulb device is scanned, and make sure that the device is not connected by other apps or mobile phones when the light bulb is using the demo.

3. If none of the above works, can you provide a video? The video includes scanning to the device using the Tuya app and do not click. Use the demo to scan at this time.

Hi! Is there any update on this one? Did it work for you?
