== Commandes générales ==
The following general purpose commands are available on all Bluefruit LE modules:
The following general purpose commands are available on all Bluefruit LE modules:
== AT+FACTORYRESET ==
Clears any user config data from non-volatile memory and performs a factory reset before resetting the Bluefruit module.
* Codebase Revision: 0.3.0
* Parameters: None
* Output: None
<nowiki>AT+FACTORYRESET
OK</nowiki>
{{ambox-stop|text=As of version 0.5.0+ of the firmware, you can perform a factory reset by holding the DFU button down for 10s until the blue CONNECTED LED lights up, and then releasing the button.}}
== AT+DFU ==
Forces the module into DFU mode, allowing over the air firmware updates using a dedicated DFU app on iOS or Android.
* Codebase Revision: 0.3.0
* Parameters: None
* Output: None
{{ambox-stop|text=The AT parser will no longer responsd after the AT+DFU command is entered, since normal program execution effectively halts and a full system reset is performed to start the bootloader code.}}
<nowiki>AT+DFU
OK</nowiki>
== AT+HELP ==
Displays a comma-separated list of all AT parser commands available on the system.
* Codebase Version: 0.3.0
* Parameters: None
* Output: A comma-separated list of all AT parser commands available on the system.

OK</nowiki>
== AT+NVMWRITE ==
Writes data to the 256 byte user non-volatile memory (NVM) region.
* Codebase Version: 0.7.0
* Parameters:
** offset: The numeric offset for the first byte from the starting position in the user NVM
** datatype: Which can be one of STRING (1), BYTEARRAY (2) or INTEGER (3)
** data: The data to write to NVM memory (the exact payload format will change based on the specified datatype).
* Output: Nothing
<nowiki># Write 32768 as an integer starting at byte 16 in user NVM
AT+NVMWRITE=16,INTEGER,32768
OK</nowiki>
== AT+NVMREAD ==
Reads data from the 256 byte user non-volatile memory (NVM) region.
* Codebase Version: 0.7.0
* Parameters:
** offset: The numeric offset for the first byte from the starting position in the user NVM
** size: The number of bytes to read
** datatype: The type used for the data being read, which is required to properly parse the data and display it as a response. The value can be one of STRING (1), BYTEARRAY (2) or INTEGER (3)
* Output: The data read back, formatted based on the datatype argument.
<nowiki># Read an integer back from position 16 in user NVM
AT+NVMREAD=16, 4, INTEGER
32768
OK</nowiki>
== AT+MODESWITCHEN ==
Enables or disables mode switches via the '+++' command on the BLE peripheral of BLE UART side of the connection.
* Codebase Version: 0.7.1
* Parameters:
** location: This can be a string, either 'local' or 'ble' indicating which side should have the '+++' command enabled or disabled, 'local' being the Bluefruit peripheral and 'ble' being the phone or tablet.
** state: '0' to disable '+++' mode switches, '1' to enable them.
** Output: None
{{ambox|text=By default, '+++' is enabled locally, and disabled in BLE}}
<nowiki># Disable reomte '+++' mode switches
AT+MODESWITCHEN=ble,0
OK</nowiki>
