2.3 Changes from CC2560A and CC2564 to CC2560B and CC2564B Devices
The CC2560B and CC2564B devices include the following changes from the CC2560A and CC2564
devices:
• From a hardware perspective, both devices are pin compatible. From a software perspective, each
device requires a different service pack. When operating with the two devices using the supported
Bluetooth stack, the devices are integrated seamlessly and use remains identical for each device.
• Assisted mode for the HFP1.6 (WBS) profile or the A2DP profile to enable more advanced features
without using host processing or power
• Support for the H5 protocol in the UART transport layer using 2-wire UART
• Enable 10 Bluetooth LE connections
