2.5.20 K,1
The Kill command disconnects the current connection. The characters KILL <cr><lf>
are echoed to the local UART once the connection is broken.
Example:
2.5.21 N,<address>
This command removes a device from the paired device list. The RN4677 is able to
store up to four devices. The paired device list can be displayed by issuing command
Y.
This command expects one parameter. The parameter can be letter
Z, indicating to
remove all devices from the paired device list, or the parameter can be hex value of a
MAC address. This command removes the device with the input MAC address from the
paired device list. If input MAC address is not associated with one of the devices in the
paired device list, an error information is displayed.
Example:
2.5.22 O
This command displays other settings such as the configuration character.
Example:
2.5.23 Q
This command puts the device into Quiet mode, which means it is temporarily not dis-
coverable or connectable. When this command is issued, the device responds
Quiet.
This command does not survive a power cycle or Reset.
The
Q command settings with different responses include:
• Q - The module is undiscoverable for both Bluetooth Classic and BLE
• Q,0 - The module is discoverable and able to connect for both Bluetooth Classic
and BLE. Response is AOK.
• Q,1 - The module is not discoverable and not able to connect for both Bluetooth
Classic and BLE
• Q,2 - The module is able to connect but is not discoverable in Bluetooth Classic
• Q,3 - The module is not discoverable in BLE
• Q,? - Displays the current quiet mode
Example:
2.5.24 R,1
This command forces a complete device reboot (similar to power cycle).
Example:
K,1 // Disconnect the current connection
N, 00A053112233 // Remove device with MAC address
// 00A053112233 from paired device list
N,Z // Clear paired device list
O // Show the other settings
Q // Make module undiscoverable
Note: Any changes to the device configuration using the Set commands do not
take effect until the device is rebooted.
R,1 // Reboot device
Command Reference

2.5.25 T,<H16>,<H16>,<H16>,<H16>
This command only applies to BLE.
This command adjusts the connection parameters after establishing the BLE
connection.
The first parameter is a 16-bit hex value for minimum connection interval with unit of
0.625 ms.
The second parameter is a 16-bit hex value for maximum connection interval with unit
of 0.625 ms.
The third parameter is slave latency.
The fourth parameter is supervision timeout with unit of 10 ms.
Example:
2.5.26 V
This command displays the firmware version.
Example:
2.5.27 W
This command is the same as command Q,0. It is implemented for backward
compatibility.
This command enables discovery and connection after it has been disabled with the
Q
command. It reloads the stored value of the inquiry and page window to re-enable.
Example:
2.5.28 X
This command is a combination of commands D, E and O to display configurations.
Example:
2.5.29 Y[,1]
Command Y displays the MAC addresses of devices in the paired device list. Option-
ally, if parameter
1 is provided, the indexes of the MAC address of devices in the paired
device list are also displayed. The index is useful if the user plans to use command
C<1-4> to reconnect device in the stored device list.
Example:
T,0010,0020,0000,0100 // Adjust the connection parameter to be
// min_conn_interval: 10 ms
// max_conn_interval: 20 ms
// slave_latency: 0
// supervision timeout: 2.56 seconds
V // Display the firmware version
W // Turn on discovery and connections
X // Display configurations
Y // Display MAC addresses of devices in
// the stored device list

2.5.30 Z
This command only applies to BLE.
Command
Z cancels attempt to establish a BLE connection by C command before a
connection is established.
Example:
Z // Cancel attempt to establish a BLE
// connection.
