Cannot connect with sample project "smp_svr" on Android App

[moeBabazadeh]

When trying to connect to a device using the "smp_svr" sample from the Nordic Connect SDK on an Android app, the connection doesn't hold. After briefly connecting, it immediately disconnects, showing reason code 0x08. This happens consistently across my two Android 8 devices.

Steps to Reproduce:

• Burn the "smp_svr" sample on a "NRF52840 dongle".
• Connect to the device using the Android app.
• Notice that the connection gets established but quickly disconnects with reason code 0x08.
• Repeat these steps on various Android devices to see the same result.

Expected Behaviour:

• The connection should stay stable without disconnecting immediately after being established.

Additional Information:

• Connecting to the same device works fine with the nRF Connect mobile app on both Android and iOS.
• Device Manager app on iOS can also connect and perform DFU successfully.
• Logs from the device show successful connection followed by immediate disconnection, then advertising restarts.

Environment:

• Android Devices Used: [Huawei Nova 2, Huawei Mate 10 light]
• Nordic Connect SDK Version: [2.5.0, 2.5.1]

Attempted Solutions:

• Tried reconnecting multiple times without success.
• Confirmed the issue occurs on different Android devices.
