2.5.11 CFR
This command causes the device to connect and immediately go into Fast Data mode
using the stored remote address.
Example:
2.5.12 F,<0, 1>
This command puts the RN4677 into Fast Data mode.
If the parameter is
1, Fast Data mode is enabled; otherwise, Fast Data mode is dis-
abled. Fast Data mode improves data transfer throughput by disabling check for
escape characters to enter Command mode.
When RN4677 is connected to another device, enabling Fast Data mode exits Com-
mand mode immediately and puts the device into Fast Data mode; when RN4677 is
not connected to another device, enabling Fast Data mode puts RN4677 into Fast Data
mode once it connects to another device.
Example:
2.5.13 H
The Help command displays a list of commands and their basic syntax.
Example:
2.5.14 I,<value 1>,<value 2>
This command only applies to Bluetooth Classic.
This command performs an inquiry scan, where <value 1> is the scan time in seconds
and <value 2> is the optional COD of the device class being scanned. The default time
is 10 seconds, and the maximum is 48 seconds. If <value 2> is unused or set to
0, the
device looks for all device classes. When entering a COD, all six hex characters must
be provided. For example, enter
0040F0 for COD 0x40F0 value. The scan returns a
maximum of nine devices. As devices are found, they are displayed in the following
format:
<Bluetooth address>,<Bluetooth name>,<COD>
00A053000123,MySerial-Port,72010C
Default:
10 seconds, no COD
Example:
2.5.15 IL[,<H8>,<H16>,<H16>]
This command only applies to BLE.
This command scans the neighborhood for BLE devices. This command can take up
to three parameters.

Note: Once in Fast Data mode, it is impossible to enter Command mode unless
the remote side drops the connection or hardware Reset is invoked to
reboot the module.
F,1 // Leave Command mode and enter Fast Data mode
H // Display help
I,20,0040F0 // Scan for 20 seconds using the COD 0x40F0
