Bluetooth serial adapters
View Patent ↗A Bluetooth serial adapter comprising a Bluetooth connection module ( 21 ) for conducting Bluetooth communication with another Bluetooth enabled device, a serial connector SP allowing connection of a serial cable between the adapter and a device having a serial port, and a serial to Bluetooth interface ( 23 ) arranged for: receiving serial connection control commands input via the serial connector; mapping received serial connection control commands to Bluetooth connection control events; and outputting the so determined Bluetooth connection control events to the Bluetooth connection module. The interface ( 23 ) may be implemented by making use of a virtual machine provided on the Bluetooth chip.
1. A Bluetooth serial adapter comprising a Bluetooth connection module for conducting Bluetooth communication by transmitting and receiving Bluetooth radio frequency signals with another Bluetooth enabled device, and a first serial port which allows connection of the adapter to a device having a second serial port,
wherein the serial adapter further comprises a serial to Bluetooth interface arranged for:
receiving serial connection control commands input via the first serial port;
mapping received serial connection control commands to Bluetooth connection control events; and
outputting the so determined Bluetooth connection control events to the Bluetooth connection module, wherein the serial connection control commands form a set that is smaller than an array formed by the events provided in Bluetooth.
2. A Bluetooth serial adapter as claimed in claim 1 , wherein the first serial port has a serial connector which allows connection of a serial cable between the adapter and a device having a second serial port.
3. A Bluetooth serial adapter according to claim 1 in which each serial connection control command is mapped to a corresponding Bluetooth event but there is at least one Bluetooth event that has no corresponding serial connection control command.
4. A Bluetooth serial adapter according to claim 1 in which the serial connection control commands comprise a command set having commands which are one of:
analogous to, directly related to, and substantially identical to, commands used in an industry standard command set used in controlling Modem connections.
5. A Bluetooth serial adapter according to claim 1 in which the serial connection control commands comprise a set of AT commands.
6. A Bluetooth serial adapter according to claim 1 in which the Bluetooth connection module comprises a Bluetooth chip carrying a programmable virtual machine programmed to act as the serial to Bluetooth interface.
