Commands that return payload data use the format:

<command character> is one character from the set: [a-z]

<command type> is one character for the set: [0-9]

<command payload> is variable in length.

<CR> is the command terminator.

The command character is the “lower case” version of the local host com-

mand.

Operating Modes

Themoduleinterfacehastwomodes:

S Bluetooth Link Active State : I n this case the Serial Interface looks like a

raw serial port (TxD, RxD, CTS, etc. and GND). There is no intelli-

gence in the B luetooth module from the serial interface perspective.

This mode does not support the command and control modes described

below.

S Bluetooth Link Inactive State : This mode exists when a Bluetooth link

is not existent: In this case, the serial interface looks like a serial port

that supports a number of command and control modes.

Upon reset, the unit comes up in “Bluetooth Link I nactive S tate.” After

the f irst Bluetooth connection, the unit goes into “Bluetooth Link A ctive

State.” It stays in this state until the link is lost because the Master shuts it

down or there is a n out-of-range condition. At this point, it returns to the

“Bluetooth Link Inactive State.”
