2.3.9

SM,<value>

This command sets the mode, where <value> is a number as shown in Table 2-2.

Default:

0

Example:

2.3.10

SN,<string>

This command sets the device name, where <string> is up to 16 alphanumeric

characters.

Default:

N/A

Example:

2.3.11

SO,<string1>[,<string2>]

This command sets the extended status string, where <string1> and <string2> are up

to four alphanumeric characters each. Setting these strings to from one to four

characters permits status messages to be sent to the RN4677 UART port. The first

string is the prefix to the message, and the optional second string is the postfix to the

message. For instance, when a Bluetooth Classic connection is established, the device

sends the string <string1>CONNECT<string2>.

If the first parameter is a space, then both prefix and postfix are cleared, and no

extended status string becomes an output.

Default:

%,%

Example:

2.3.12

SP,<string>

This command sets the security pin code, where <string> is either a 4-digit or a 6-digit

pin. The 4-digit pin is used for legacy pin code pairing, while the 6-digit pin is used for

SSP authentication in BLE if a fixed pin is desirable. The fixed 6-digit pin code in BLE

is not supported by many of the Bluetooth Low Energy implementations.

Default:

1234
