Hello Folks,

Using Bluez 5.30 based controller acting as Slave Role, I would like to prevent/delay the send Connection Parameter Update Request just after successful connection. 

Steps of Communication b/w Host and Controller:
1. Contoller prepared in connectable mode by issuing command:  hciconfig hci0 leadv
2) Below is the communication sequence:
        (H -> C): Type: Command opcode: 0x200d - Create Connection
        (C -> H): Type: Event   opcode: 0x200d - Command Status
        (C -> H): Type: Event                  - LE Connection Complete
        (C -> H): ACL Data:  Connection Parameter Update Request

Is it possible to disable/delay controller to send Connection Parameter Update Request or send it with any delay?


Some Info on the Modes set on Controller:
