Power Saving:<br />
• Full support for all Bluetooth power saving modes (Park, Sniff and Hold).<br />
Data Integrity:<br />
• CQDDR increases the effective data rate in noisy environments.<br />
• RSSI used to minimize interference to other radio devices using the ISM band.<br />
Notes:<br />
1. The data rate is with respect to WT12 with basic data rate packets.<br />

Figure 25: WRAP THOR VM Stack<br />
In figure 26, this version of the stack firmware shown requires no host processor (but can<br />
use a host processor for debugging etc.). All software layers, including application<br />
software, run on the internal RISC processor in a protected user software execution<br />
environment known as a Virtual Machine (VM).<br />
The user may write custom application code to run on the BlueCore VM using BlueLab<br />
software development kit (SDK) supplied with the Casira development kit, available<br />
separately from Bluegiga or directly form CSR. This code will then execute alongside the<br />
