3.1 Command Mode
The command mode is the default mode when iWRAP is powered up. In command mode,
ASCII commands can be entered to iWRAP to perform various functions.
Note:
 In command mode if there are active Bluetooth connections, the data from remote
devices is buffered into iWRAP buffers.
 Because of the embedded nature of iWRAP, buffering capabilities are low and only
small amounts of data can be received to buffers. The amount of data which can be
buffered depends on the firmware version and the state of iWRAP. Usually, it is
around 1000 bytes, but may vary radically.
 LIST command shows active connections, as well the amount of buffered data.
3.2 Data Mode
Data mode is the default mode when there are one or more Bluetooth . In data mode, all
data is sent transparently from UART interface to the Bluetooth link and vice versa.
Note:
 When iWRAP enters command mode, a “ READY ” event occurs, unless events are
masked away with “
4
SET CONTROL ECHO ” command.
 DTR pin can be used instead of escape sequence to switch from data mode to
command mode and it allows much faster mode switching so no guard time is
needed. DTR pin can be enabled with “
SET CONTROL ESCAPE ” command.
 The escape character can also be changed by with “ SET CONTROL ESCAPE ”
command.
 Carrier Detect (CD) pin can also be used to indicate either a Bluetooth connection
or data mode. CD pin can be enabled with “ SET CONTROL CD ” command.
