Datasheet
General Purpose
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
AT+FACTORYRESET
OK
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
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
AT+DFU
OK
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
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
# Write 32768 as an integer starting at byte 16 in user NVM
