Cannot Connect to more than 9 - Android 13

[scott-olero]

Describe the bug We have been able to connect to 12 slaves but after Android 13 update we can only get a maximum of 9 slaves.

To Reproduce Steps to reproduce the behavior:

1. Connect to more than 9 slaves

Expected behavior The 10th slave wont connect , seems to be blocked by the Android 13 OS.

• [ ] I tried doing the same with a general BLE scanner application (e.g. nRF Connect) and it exhibits the expected behavior as described above

Smartphone / tablet

• Device: [Samsung Active TAB 3]
• OS: [ Android 13]
• Package version: [e.g. 1.1]

Peripheral device

• Vendor, model: [ CUSTOM - Silicon labs bgm210]
• Does it run a custom firmware / software: yes

did you receive an error message in the logs? As far as I know we do not limit the amount of subsequent connections power I know that connecting to > 9 devices is a discouraged use case.

Hi @remonh87 we did not get any errors . We optimized the app to connect reliably with 12 sensors, but its seems like the issue is an Android 13 OS issue rather than a Library issue.
