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
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
AT+DFU OK
AT+HELP
Displays a comma-separated list of all AT parser commands available on the system.

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 AT+NVMWRITE=16,INTEGER,32768 OK
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.
# Read an integer back from position 16 in user NVM AT+NVMREAD=16, 4, INTEGER 32768 OK
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
# Disable reomte '+++' mode switches AT+MODESWITCHEN=ble,0 OK
