BLE
Generic
The following general purpose BLE commands are available on Bluefruit LE modules:
AT+BLEPOWERLEVEL
Gets or sets the current transmit power level for the module's radio (higher transmit power equals better range, lower
transmit power equals better battery life).
Codebase Revision: 0.3.0
Parameters: The TX power level (in dBm), which can be one of the following values (from lowest to higher transmit
power):
-40
-20
-16
-12
-8
-4
0
4
Output: The current transmit power level (in dBm)
# Get the current TX power level (in dBm)
AT+BLEPOWERLEVEL
0
OK
# Set the TX power level to 4dBm (maximum value)
AT+BLEPOWERLEVEL=4
OK
# Set the TX power level to -12dBm (better battery life)
AT+BLEPOWERLEVEL=-12
OK
# Set the TX power level to an invalid value
AT+BLEPOWERLEVEL=-3
ERROR
AT+BLEGETADDRTYPE
Gets the address type (for the 48-bit BLE device address).
The updated power level will take affect as soon as the command is entered. If the device isn't connected to
another device, advertising will stop momentarily and then restart once the new power level has taken affect.
