[bluetooth][PTS] Getting Connection failed to be established ocasionally

[MariuszSkamra]

Trying to connect to PTS, Im getting connection failed to be established occasionally.

Reproducible 2/10
TestCase: GATT/CL/GAD/BV-03-C
IUT: Zephyr, nRF52840PDK

Reproduce with bt shell:

connect 00:1b:dc:08:e6:83 (public)
gatt-discover-include
disconnect

Procedure repeats few times

The sniffer trace that has been uploaded does not show a connection that disconnected with that error code, but there is a hole in the sniffer trace , so it might be that the sniffer missed it. Can we get a new sniffer trace?

Also could you provide some more information to help me reproduce the issue?

• Which device is central.
• which device is peripheral.
• a specific commit
• Any special configuration

So far I haven't been able to reproduce the frequency of connection failed that you describe. But in a noisy environment this behaviour is expected. A CRC error on the connect request could be the cause.

@MariuszSkamra Are you still seeing this with recent runs of PTS?

@cvinayak what is the status of this issue?

[cvinayak]

we should close this, as there has been no follow up on reproducing it since Sept 21 and I have run conformance tests as part of v1.14.0-rc1 testing that passes all conformance tests.

Closing as non-applicable anymore.
