normal mode, the data is stored to small iWRAP buffers and received when the

connections become active (data mode of the connection enabled).

The next figure illustrates the host-iWRAP-host communications in multiplexing mode.

Figure 4:

Host-iWRAP-Host communication

The figure below illustrates host-iWRAP-remote device communication when multiplexing

mode is in use. The key thing is that the remote device does not need to know anything

about the multiplexing communication and frame format, but it sees the connection as a

standard

Bluetooth

connection.

Host-iWRAP-remote device communications

At the moment, four (4) simultaneous connections can be used in multiplexing mode.

Tips:

In MUX mode the processor of the module is highly utilized and on the edge of its

performance. This may be seen as a instability of

Bluetooth

connections, especially if 3 or

more connections are used or data rate is high. There are however a few tricks how the

stability of the

Bluetooth

connections can be improved:

Use SNIFF mode: Using sniff mode reduces the rate the master device needs to poll

the active connections are leaves more time for the processor to parse or generate

the multiplexing protocol. Therefore as aggressive as possible sniff mode should be

used.

Optimize

Bluetooth

packet size by using MTU option in CALL command: Using

smaller

Bluetooth

packet size improves the multiplexing performance.

On the next page, there is a simple C-code example on how to create a simple

multiplexing frame containing an iWRAP command.
