MF Put Device into Fast Data Mode<br />
This command forces the radio into Fast Data Mode on channel 00 only. In order for this to have an<br />

data. Ways to get out of this mode are to reset power on the radio or strobe PIO(4) while connected.<br />

Note: Strobe PIO(4) >5ms to take the device out of fast data into command mode and<br />
maintain the <strong>Bluetooth</strong> RF connection. If not RF connected, the device will be placed in<br />
command mode.<br />
Utilities – Cancel Command<br />
UCL Cancel<br />
The UCL command tells the radio to cancel inquiry or connect request commands and then place the<br />
radio in Idle Mode. This command can come in handy for a quick exit from commands like inquiry<br />
mode if there are no devices in the area and you do not want to wait for an automatic timeout. You<br />
can not issue a cancel command while RF connected.<br />
This command can also be used to break out of the auto-master connect mode. If executed while<br />
connected in this mode, the radio will disconnect and enter idle mode instead of attempting to<br />
connect again.<br />
