The module is completely restored to factory defaults. All settings are reset to default values.
All certificates and Bluetooth bonding information will be removed.


Notes:
Requires AT&W and a reboot before taking effect.

Reset all settings to default values.
Certificates and Bluetooth bonding information will be left untouched.


Notes:
Requires AT&W and a reboot before taking effect.

Configure new UART settings that will be used after restart. Baudrates above 4000000 bps can be set, but are unsupported. If the flow_control parameter is omitted then no flow control will be used. If change_after_confirm is not provided the baudrate will be changed only after a store and reboot.

Notes:
Can be stored using AT&W.

change_after_confirm

integer

0: Switch baudrate after reboot. When set AT&W must be called.
1: Switch baudrate directly after status OK have been sent.

Write escape character. This settings change the decimal value of the escape character used by some modes, such as transparent mode for example, to detect an escape sequence and exit.

Notes:
Can be stored using AT&W.

Write line termination character. This setting changes the decimal value of the character recognized by the DCE from the DTE to terminate an incoming command line. It is also generated by the DCE as part of the header, trailer, and terminator for result codes and information text along with the S4 parameter. The previous value of S3 is used to determine the command line termination character for entry of the command line containing the S3 setting command. However, the result code issued shall use the value of S3 as set during the processing of the command line. For example, if S3 was previously set to 13 and the command line “ATS3=30” is issued, the command line shall be terminated with a CR, character (13), but the result code issued will use the character with the ordinal value 30 instead of the CR.

Notes:
Can be stored using AT&W.

Write response format character. This setting changes the decimal value of the character generated by the DCE as part of the header, trailer, and terminator for result codes and information text, along with the S3 parameter. If the value of S4 is changed in a command line, the result code issued in response to that command line will use the new value of S4.

Notes:
Can be stored using AT&W.

Writes backspace character. This setting changes the decimal value of the character recognized by the DCE as a request to delete from the command line, the immediately preceding character.

Notes:
Can be stored using AT&W.
