Android 12 Support

Question

Hey guys I’m wondering that if you have in plan to add support for Android 12 any time soon, cause I started to test how my app is working on Android 12 and I have some problems. When I’m disconnecting from the device I’m getting this error:

{
message: "Device ......... was disconnected"
errorCode: 201
attErrorCode: 0
iosErrorCode: null
androidErrorCode: null
reason: "Disconnected from ........... with status 0 (GATT_SUCCESS)"
name: "BleError"
}

which is good but attErrorCode is always 0 no matter what I do, I tried to go out of range, reset the device but the attErrorCode is not changing. I tested on a physical device Pixel 5 with Android 12 Beta 5. I couldn’t replicate this problem on any other device with any other version of android. I’m asking this question because I saw that Google made some changes around the Bluetooth permissions and I’m wondering if this might affect this library somehow. Currently, I’m running on: “react-native”: “0.63.3” “react-native-ble-plx”: “^2.0.2” So, can you please tell me if the Android 12 can impact you guys somehow and if you have anything planned to support Android 12?

@mciechanowicz @bor-ski, sorry to tag you here, but we would need some help with this, or some clarity on the maintenance of the repo.

Currently, react-native-ble-plx uses a version of https://github.com/dotintent/MultiPlatformBleAdapter which is not wrapping the latest RxAndroidBle library. Instead it wraps an old version of RxAndroidBle which does runtime checks on the permissions, requiring the Location permissions on Android 12 (with targetSdkVersion 31+) while it’s not needed, even if the new Bluetooth Permissions are granted. The latest version of RxAndroidBle doesn’t have this issue.

It looks like the update should go in two steps:

• Update the https://github.com/dotintent/MultiPlatformBleAdapter so it uses the latest RxAndroidBle library. (can be tricky because you move from RxJava 1 to 2)
• Then update react-native-ble-plx so it uses the updated MultiPlatformBleAdapter

Could you please clarify the status of the react-native-ble-plx project since .intent took ownership? Should we look at alternative libraries? Forking and fixing it ourselves could be a solution, but if the project is no longer maintained by a community, and if the fixes never land on the main branch, it may not be a viable long term solution.

Thanks

Hi @fabiendem and others

That’s exactly what we did here react-native-ble-plx We updated MultiPlatformBleAdapter to use the latest RxAndroidBle

We also pushed it to NPM

Not sure if it’s bulletproof, we didn’t go as far as using it in production yet but preliminary testing shows that it works well on Android 12.

It’s really sad that this library is no longer maintained.
