Android Gatt Error Code 133(0x85).

[NikhilSavaliya]

Hey,

I am facing a common issue in which I have seen multiple users. When I try to connect Gatt Server I got disconnection with Error code 133(0x85). and also we also have enabled compatibility mode 2 in our Firmware which is mentioned in the following reference. The issue with connection is happening more frequently with android only as it is working fine with iOS. I have tested with various android devices with different manufactures also. Tested Devices Moto g6(Android 9), Xiaomi Redmi 3S (Android M), Oneplus Nord(Android 10), Google Pixel(Android 10), Samsung Galaxy S7 (Android  8.0.0).

Please share a solution or problem which needs to address either the android side or firmware side.

We need a sniffer trace of a failing connection. 

I have tested with various android devices with different manufactures also.

 Do you see the same issue with BLE devices other than Nordic's?
