action is taken (in addition to the actions explained above). The special
action involves saving the currently configured device information to
Flash. This will allow the possibility for the device to automatically boot
into this mode when restarted. This is useful if the host does not want to
reconfigure the device or further interact with the device. It should be
noted that when this happens, the device will boot directly into data
mode, and the host will have to perform one of the methods listed above
to re-enter command mode. If the store to Flash setting has not been
enabled for the automatic mode setting then this special processing does
not occur.
The final (optional) parameter, the connection period, allows a
mechanism for the device to conserve power. Power is conserved
because the device can be told to delay (sleep) for a specified duration
when attempting to connect to the remote device (if the prior attempt
failed). This is only useful in automatic mode where the device will not
return to command mode and will always attempt to reconnect to a
device when it is disconnected. By specifying a non-zero period (in
seconds) the device can wait for the specified duration and re-attempt a
connection. If this period is zero, the device will continually attempt to re-
connect when a connection attempt fails. When power consumption
should be as low possible, the continuous connection attempt scenario is
not very optimal. When the device is not in automatic mode, the
connection period is ignored (only the connection attempt parameter is
used).
Format:
AT+BTCLT=<BDADDR>, <Port>, <Attempts>, <Period>
where,
<BDADDR> is the 12 digit ASCII coded hexadecimal Bluetooth
Device address of the remote Bluetooth device to connect with.
This value is required to be 12 digits (note that this value is not
preceded with the “ \x ” or the “ \X ” prefix).
<Port> is an integer value that represents the Bluetooth
RFCOMM port number that is to be connected (1-30). This
parameter can either be an integer value or a hexadecimal value
(preceded by “ \x ” or “ \X ” without the quotation marks 0x01 –
0x1E). This value is required. This value can be determined (if
not known in advance) by performing a Service Discovery
Protocol (SDP) search. See the AT+BTSDP command for more
information.
<Attempts> is an optional integer parameter that specifies the
number of connection attempts that are to be attempted before
either returning to command mode or sleeping for the specified
period. This value can be either an integer value (1-255) or a
hexadecimal value (preceded by “ \x ” or “ \X ” without the quotation
