Performs an inquiry scan. Default time is 10 seconds, maximum is 48. COD
parameter is optional, 0 or no entry looks for all device classes. When entering a
COD you must provide all six characters, i.e. 0040F0 for COD 0x40F0. A maximum
of 9 devices will be returned. As devices are found, they are displayed in the format
below:
Performs an inquiry scan like the I command but does not return the Bluetooth name
so it returns much faster since getting the name requires a remote lookup for each
device found.
Performs an inquiry scan, with a COD of 0x001F00, which is the default COD for
Roving Networks Serial adapters and modules.
Performs an inquiry scan, with a COD of 0x0055AA, which is the special COD used
By Roving Networks Serial adapters and modules to enable “instant cable
replacement”.
Help, will print out a list of commands and their basic syntax
Kill (disconnect) from the current connection. The characters KILL<cr><lf> will be
echoed to the local UART once the connection is broken.
Link Quality. Returns real-time streaming link quality values at 5Hz. Value
returned is a two bytes separated by a comma. A value of “ff” is the highest value.
The first byte is the current reading the second byte is the low water mark.
Example output:
Passes thru any characters up to a CR or LF while in command mode.
Causes device to be non-discoverable and non-connectable (temporarily). Does not
survive a power cycle or reset. Used with the Z command below. Use the “W”
command to re-enable.
This command will return “Quiet” as a response.
To get the lowest power mode, first issue a Q, then a Z. Use the SNIFF settings to
get lowest power while connected.
Forces a complete reboot of the device (similar to a power cycle).
Pass receive data (from UART or BT) while in command mode. Returns (T=0 , T=1
based on input).
Re-enables discovery and connection. This command reloads the stored value of the
Inquiry and Page Window to re-enable. For example, to turn off Discovery but still
allow connections, send an “SI,0000” command, and follow it with “W” command.
This command returns “Wake” as a response.
