CC2564C: ACL connection and disconnection issue

Jonathan Wang

Part Number: CC2564C

There are two chip issues:

1. From frame 624, the host wants to disconnect the ACL link, but the controller tells that Unknown Connection Identifier at frame 626. But in fact, the ACL connection is valid.

2. From frame 633, the host wants to create connection again, but the controller tells that the ACL connection already exists. So why? The controller send event to show that the previous connection has been disconnected at frame 627.

So it seems that there is some problem with the cc2564c chip?

That is strange. Can, you please provide the following details:

a) Which host is being used and which stack (Bluetopia or Bluez)

b) Do, you see this issue consistently?

Also, can you please take FW logs along the HCI dump logs to correlate..

Thanks

Thanks for your attention.

Here is my reply on your questions:

a) The host chip is Accordo5 from ST and the stack is bluego from cybercom

b) No, this issue does not happen with 100% opportunity. But if this issue has happened, then local controller cannot make connection with

the same remote cell phone, but can make connection with another remote cell phone.

I had tried for many times to reproduce this issue, but cannot reproduce sadly.

The firmware I used is the latest version which released on 22-Oct-2019.

Without FW logs, it is difficult to diagnose what is wrong. It appears, due to some reason the FW things the connection is still up.. May be the remote side has not acked a termination etc?

Thanks
