Appendix B — Bluetooth Configuration Commands and Specifications
When using percent (%) to form hexadecimal character codes there
must be exactly two hex digits using characters: [0-9, A-F, a-f].
Characters outside of this range cause the command to fail.
• Commands that fail return the four character sequence
• Commands that are accepted return the four character sequence
ACK<CR>
• Commands that return payload data use the format:
<command character><command type><coCK61mmand
payload><CR>
<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
command.
The module interface has two modes:
• Bluetooth Link Active State
In this case the Serial Interface looks like a raw serial port (TxD,
RxD, CTS, etc. and GND). There is no intelligence in the
Bluetooth module from the serial interface perspective. This mode
does not support the command and control modes described
below.
• Bluetooth Link Inactive State
This mode exists when a Bluetooth link does not exist. In this case,
the serial interface looks like a serial port that supports a number
of command and control modes.
On reset, the unit comes up in Bluetooth Link Inactive state. After the
first Bluetooth connection, the unit goes into Bluetooth Link Active
state. It stays in this state until the link is lost because the Master
shuts it down or there is an out-of-range condition, it then returns to
the Bluetooth Link Inactive state.
NAK<CR>
