of 9 devices will be returned. As devices are found, they are displayed in the format

below:

00A053000123,MySerialPort,72010C

IN<time>,<cod> 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.

IS<time> Performs an inquiry scan, with a COD of 0x001F00, which is the default COD for

Roving Networks Serial adapters and modules.

IR<time> 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”.

H Help, will print out a list of commands and their basic syntax

K, Kill (disconnect) from the current connection. The characters KILL<cr><lf> will be

echoed to the local UART once the connection is broken.

L 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:

RSSI =ff,e6

P,<char> Passes thru any characters up to a CR or LF while in command mode.

Q 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.

R,1 Forces a complete reboot of the device (similar to a power cycle).

T,<0,1> Pass receive data (from UART or BT) while in command mode. Returns (T=0 , T=1

based on input).

W 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.
