CC256x Service Packs - BTS Format

The CC256x Bluetooth Service Packs (SP) are mandatory initialization scripts that contain bug fixes and platform specific configurations. They must be loaded into the corresponding CC256x device after every power cycle. The CC256x SPs are delivered in the form of a Bluetooth Script (BTS) file. A BTS file is a scripted binary file which defines the actions that should be applied to the embedded HCI commands and HCI events within the file itself.

This page holds all the Service Packs (SP) required for proper operation by the different variants of TI Bluetooth device CC256x. As noted previously, the CC256x SP must be loaded first during initialization each time the device boots up.

CC256xB - Updated Fixes in Service Pack 1.0


Subject Description Comments

BT SIG

BT 4.1 support
No new features were added

Host I/F

Added new event "vs_reject_voice_link_event" upon remote attempting to establish 3rd voice connection (2 voice connections are already active)

ETSI

ETSI 300 328 version 1.8.1 might still have failed despite the fix in service pack 0.2

Stability

Remote name request during A2DP data streaming might have resulted in BT getting stuck

Stability

When running loop of BLE connect-disconnect (with page scan running in background), slave side might get stuck at establishment of BLE connection

Assisted A2DP

Add support for host flow control in assisted A2DP SNK

Assisted A2DP

Fix occasional drop outs in assisted A2DP SNK

BLE

BLE slave ignored "LL terminate" indication if was busy with other peer transaction

Current Consumption

High current draw due to slave exiting latency from reception of “LL channel map” or “LL connection update” until instant

Current Consumption

Device did not enter deep sleep in sniff mode after setting LSTO to 5 seconds



CC256xB - Updated Fixes in Service Pack 0.2


Subject Description Comments

ETSI

ETSI 300 328 version 1.8.1

Assisted A2DP

Assisted A2DP Sink - Audio Dropout Issue

Assisted A2DP

Update Codec Configuration API to support better frequency resolution
processors.wiki.ti.com/index.php/CC256x_VS_HCI_Commands#HCI_VS_Write_CODEC_Config_.280xFD06.29

Host I/F

Added support to host flow control during assisted A2DP
 BLE Fix BLE slave latency behavior during transactions



CC2560A/CC2564 - Updated Fixes in Service Pack 2.14

CC2560A/CC2564 - Updated Fixes in Service Pack 2.12


Subject Description Comments

ETSI

ETSI 300 328 version 1.8.1

Throughput

Data streaming throughput with peer 1 drops, and stays low after attempting to connect to peer 2, and canceling create connection

Voice

WBS Audio to peer 1 lost upon connection and disconnection with any peer 2 device

Voice

Device connected with WBS to peer 1 and to peer 2. After disconnecting peer 2, when disconnecting and reconnecting to peer 1, there is no audio on peer 1

IOP

When in Master role, response to peer initiated "LMP_Feature_Request" with "LMP_Not_accepted" and reason invalid parameter, peer device crashes and connection drops
