SET CONTROL CD
This command enables or disables the carrier detect signal (CD) in iWRAP.
Carrier detect signal can be used to indicate that iWRAP has an active
Bluetooth
connection. With “
SET CONTROL CD
” command, one PIO line can be configured to act as
a CD signal.
6.15.1
Syntax
Synopsis:
SET CONTROL CD {
cd_mask
} {
datamode
}
Description:
cd_mask
This is a bit mask, which defines the GPIO lines used for CD signaling
For example, value 20 (HEX) must be used for PIO5.
20 (HEX) = 100000 (BIN)
For PIO6, the value is 40
40 (HEX) = 1000000 (BIN)
datamode
This parameter defines how the carrier detect signal works.
0
CD signal is driven high if there are one or more connections.
1
CD signal is driven high only in data mode.
Events:
SYNTAX ERROR
This event occurs if incorrect parameters are given
List format:
SET CONTROL CD {
cd_mask
} {
datamode
}
