Cannot scan Eddystone service UUID on Android with versions > 2.0.3

The bug has been confirmed and we are working on it.

Contact me if you need a beacon to test this.

Note: This problem persists with or without legacyScan: false

Could this issue be related to dotintent/MultiPlatformBleAdapter#102 ?

Hi @pwellner,
We have worked on the RN side of the issue, but we will also have to engage the Android team. This is planned for next week, so we will get back to you with an update as soon as possible.
I appreciate your patience!

[pwellner]

Good news, Thanks. Let me know if there's anything I can do to help.

@EmmaZachara, Any update? I noticed this issue appears even with v2.0.3 after upgrading to expo 50.0.11 and react-native 0.73.4.

I'll be glad to upgrade the example ble-plx-scan-bug repository if that that helps.

More info:
With expo 50.0.11 and react-native 0.73.4 on Android, the old react-native-ble-plx 2.0.3 startDeviceScan() is able to scan Eddystone beacons with uuid = null, but the new react-native-ble-plx 3.1.2 is never able to find them, even with uuid = null

Hi @pwellner
Thank you for the additional info. Our Android dev will get back to working on that tomorrow. He will write his status and further approach.

@dominik-czupryna-withintent, would you consider accepting a PR to fix this bug? I would like to fix this if you or your colleagues are open to it. To get me started, could you point me to the Android dependency repository that you think will need attention?

Hi @pwellner,
of course, feel free to open new PR, we merge smaller PRs with each release. For more complex PRs we make a release for them. Unfortunately, I wasn't able to solve this issue, and our BLE Android developer is focused on another project (at the moment the task is still in progress and unfortunately, I am not able to tell a date when it will be ready). On branch https://github.com/dotintent/react-native-ble-plx/tree/bugfix/Issue-1155 you will find your code moved to the example app (react-native-ble-plx/example/), which uses directly the code from the main directory and allows you to build the app with the changes made. Under the hood for Android, we use https://github.com/dariuszseweryn/RxAndroidBle, and our iOS is based on https://github.com/Polidea/RxBluetoothKit.

If you have any additional questions, feel free to ask, I will help if I can.
