Bluetooth Implementation Considerations
The following considerations should be taken into account when implementing this technology:
- Only one Bluetooth controller is supported.
- L2CAP links over unreliable channels are not supported.
- Flush Time-out is not supported by L2CAP. Upper layers are supposed to fail the connection when Flush Time-out is not set to the default value or negotiated down to the default value.
- L2CAP does not support dynamic reconfiguration, which allows the system to enter CONFIG mode when a connection has already been opened.
The following table shows the Sysgen variables that control the listed Bluetooth features.
| Sysgen variable | Feature |
|---|---|
| SYSGEN_BTH_GATEWAY | When this variable is set, the Bluetooth Gateway Configuration Utility feature is included in the OS image. This feature is an application that provides a sample configuration of Bluetooth as a LAN Access Point (Gateway). It is available only in headless devices. |
| SYSGEN_BTH_MODEM | When this variable is set, the Bluetooth Modem Gateway Support feature is included in the OS image. A Microsoft® Windows® CE–based device can use this feature to look like a dial up modem to other Bluetooth-enabled devices. |
| SYSGEN_BTH_CSR_ONLY | When this variable is set, the Built-in CSR Chipset Support feature is included in the OS image. This feature excludes all chipset support except for CSR in the image. |
