HI,

What are you pairing against?

Hi,

I am paring with BLE Scanner and nRF connect App on Android phone 

Asus Zenfone Max Pro (M1), bluetooth 5.0

Thanks !

Hi,

Can you provide a sniffer trace of the communication between the devices? If not, on Android devices it is often possible to save the Bluetooth HCI communication to a file, you'll have to google how to do that on your phone.

The connection settings are completely unrelated to pairing. What are your pairing settings? What is your BLE SDK version?

Best regards,
Aslak

Hi,

Thanks for your replies.

I am able to resolve this issue by setting DEFAULT_ENABLE_UPDATE_REQUEST to FALSE. 

In the example code it was already set to TRUE.

But i do not understand what effect does it have?

Why setting this to FALSE it is not disconnecting anymore.

Kindly let me know?

Thanks in Advance

Update request is relating to connection parameter update request. When you turn it off, the device will not automatically ask for updated parameters.
