Pairing and Connection parameters

[KV]

Are there any dependencies between the connection parameters configuration and pairing?

I am using nRF52840 and SDK 14.0.2 and ATT_MTU example. I am trying to add pairing to this code base using peer manager. Bonding is not enabled at this stage.

When I try to run this throughput test at max speed I get 0x3D (MIC failure) error on the client (central) side. The parameters for this test case is 2M PHY and conn_interval = 7.5ms

When I change the conn_interval to 400ms or if I run at 1M PHY, I don't see this 0x3D error and test completes normally.

Can you help me in understanding this behavior?

Not that I'm aware. Could you share your complete project or let me know how to reproduce? You always get 0x3D? Just after pairing? Do you have a sniffer trace?

[KV]

No. I don't always get 0x3D. Sometimes the test completes, but on other times the test stops midway. Currently, the portal does not allow me to login into the My Page account. Is there any other way to share my complete project?

[Petter Myhre]

MyPage is the best way. What happens when you try to log in? Let's try to fix it What is your email address? (Send me a PM here with it)

I have PM'ed you. I am still having problems logging in. Let me know.

I have forwarded your information to the administrator, but it seems he is away atm. You can of course share it here as well. Just edit your question and upload it. I just assumed you had some confidential code in there.
