How to Deal with Failure to Pair Bluetooth LE Devices with Apps for Android？

Last Updated on：2022-09-20 02:44:04

Dear customers,

Compared with earlier Android versions, Android 13 provided by Google has differences in processing advertising data to find Bluetooth Low Energy (LE) devices. As a result, if your app users update to Android 13, certain legacy Bluetooth LE devices might not be paired or connected.

Legacy Bluetooth LE devices include devices developed with Tuya Bluetooth SDK v1.3.1 and earlier on BK3432 or Tuya Bluetooth SDK v1.2.1 and earlier on other chip platforms. These SDKs were released in March 2020 or earlier.

We are urging Google to optimize respective Android features regarding this failure. Before Google releases its official fix, take the following countermeasures:

[OEM apps]

For apps developed based on Tuya's OEM App, perform the following steps:

Step 1: Update to the latest App Template v4.3.0. For more information, visithttps://developer.tuya.com/en/docs/iot/tuyaiot?id=K989rswpivu4n.
Step 2: Rebuild the OEM app.
Step 3: Update the App version on Google Play. For more information, visithttps://developer.tuya.com/en/docs/iot/google-play-version-update?id=K989rt2uvcild.
