No peripheral connection after disconnect with Android App Nordic Uart Service until mac-address of smartphone changes

[qwertynoon]

No connection after disconnect with Android App Nordic Uart Service until mac-address of smartphone changes

Multilink multirole software developed in SES studio.

Other smartphone can connect without reset of NRF52 or I should wait until first phone changes its mac-address.

No feedback (from any handle) from NRF52... just no connection

What Android devices are you having trouble with, and which one is working? Some Android devices does have issues no matter what Android version is on it I'm afraid. Some of the lower-end Samsung devices are prone to this for example. Unfortunately I don't have an extensive list of what devices specifically.

Best regards,

I use Blackview4900 and Xiaomi 9.

Anyway.

Sequence...

nrf52840 connect (central) to other nrf52833.

Android1 connect to nrf52840 (peripheral).

nrf52833 disconnect (manualy) from nrf52840

Android1 disconnect from nrf52840

Then if nrf52833 connect (central) to nrf52840 - Android1 can not connect to nrf52840 (until it mac address change. it have to pass 5 - 10 minute)without any calback.(error 0x85)

And Android2 can connect to nrf52840.(any Android. I tried 5 different phones)

But when I disconnect nrf52833 - then Andorid1 can connect.

Sorry. It is hard to explain. But I have lost a lot of time and cannot fix it
