2.3.20

S-,<string>

This command sets the serialized friendly name of the device, where <string> is up to

11 alphanumeric characters. This command automatically appends the last two bytes

of the Bluetooth MAC address to the name, which is useful for generating a custom

name with unique numbering.

Default:

N/A

Example:

2.3.21

S?,<0,1>

This command only applies to Bluetooth Classic.

The Role Switch command enables and disables the role switch, where 0 means

disable role switch and 1 means enable role switch. If the switch is set when a slave

mode device receives an incoming connection, the device tries to force a role switch,

which enables the slave to become the master.

This option is useful in situations where the local device sends high-speed data up to

the remote host, and can improve performance. While connected to this device, the

connecting host may not be able to make additional outbound (multi-point)

connections.

Default:

Example:

2.3.22

S$,<char>

This command sets the configuration detect character string, where <char> is a single

character. This setting configures the escape character to enter Command mode ($$$)

to a new character. Restoring the factory defaults returns the device to using $$$.

Default:

Example:

S-,MyDevice

// Set name to "MyDevice-ABCD"

S?,1

// Enable role switch

S$,#

// Set ### as string to go into Command mode
