Default:

Example:

2.3.2

SC,<H16>

This command only applies to Bluetooth Classic.

This command sets the service class field in the Class of Device (COD). The service

class consists of the 11 Most Significant bits in the COD. This command sets the most

significant word (msw) to create the 24-bit device class number. The inquiring device

interprets the service class to determine the service. A complete listing of available

Bluetooth service classes is referenced on the Bluetooth SIG web site at

www.bluetooth.org.

Default:

0000

Example:

2.3.3

SD,<H16>

This command only applies to Bluetooth Classic.

This command sets the class of device (COD) least significant word (lsw). The COD is

a 24-bit number that is made up of the device class with major 8-bit and minor in a

16-bit word. This command is used with the Service Class command.

Default:

1F00

Example:

To set the COD to 0x1F0123, use the following commands:

SC,001F

SD,0123

SSP Pin Code Input mode

If this mode is set when authenticating the link, a 6-digit pin is displayed at the

remote device and the local RN4677 device is required to input the pin. For BLE, if

the command

SP sets the 6-digit pin code, the pin code is automatically provided.

Ensure that the remote device supports fixed pin codes; otherwise, the

authentication fails.

Legacy Pin Code mode

This Security mode is defined in Bluetooth specification 2.0. Only Bluetooth Classic

supports this Security mode. This mode requires a fixed 4-digit pin code that is

configurable using command

SP.

SA,2

// Enable "Just Works" security mode

SC,0002

// Set service class to 0002
