Part Number:CC2564B
Hello TI-Support Team,
We tried to upgrade our BTS and discovered a new issue.
Based on the file: initscripts-TIInit_6.7.16_bt_spec_4.1.bts downloaded from:
http://processors.wiki.ti.com/index.php/CC256x_Downloads#CC256xB_-_Updated_Fixes_in_Service_Pack_1.6
Issue:
- The CC2564B tells the mobile device to support BT Core Spec 4.1.
- The mobile device send a LL_SLAVE_FEATURE_REQ command
- The CC2564B device answers with Unknown Operation
I also logged the HCI interface between µC and CC2564B.
As you can see in the attached logs there is no traffic on the HCI interface between slave feature request and unknown operation answer.
So I suppose the issue concern only the CC2564B and the BTS pack.
It seems that the BTS does not really support BT Core Spec 4.1 (LL_SLAVE_FEATURE_REQ was introduced in 4.1).
TI told us the feature delta between 4.0 and 4.1 is only optional.
It seems that some required commands are not supported.
Is there an actual BTS with Core Spec 4.0 available?
Regards Tobias
