conn_params_init() is not called when MIN_CONN_INTERVAL=7.5

[Deepak Kumar]

Hi all,

I want to update my connection parameter as follow because I want to connect with both apple and windows devices. By sniffing in Wireshark I found that my IPad device accept connection interval 15ms. And my windows device accepts 7.5ms.

In order to make successful connection in both these devices I tried to put my MIN_CONN_INTERVAL=7.5 and MAX_CONN_INTERVAL=40.

I am not getting L2CAP Connection Parameter Update Request in Wireshark when my MIN_CONN_INTERVAL=7.5. But if I put my MIN_CONN_INTERVAL>=20 then I am receiving L2CAP Connection Parameter Update Request in Wireshark.

Can someone please guide me what wrong I am doing here. Because I want my connection parameter update request 7.5 and also my connection interval should be MIN_CONN_INTERVAL=7.5 and MAX_CONN_INTERVAL=40.

Thanks!!

Hello, has someone looked into this issue? Is the problem clear for you Nordic guys? Should I provide more information? Thanks

Do you know what the actual connection interval was when the CPU request wasn't sent? I believe the Connection Parameters Negotiation module only will send a CPU request if the actual connection interval is outside min and max.
