The module can transmit data through UART and remote low energy Bluetooth. When powered the module, it will enter in communication mode or configuration mode based on the level value of the ModeSW pin.
In communication mode, the module has 3 connection modes:
In configuration mode, the user can configure the module parameters, such as device name, baud rate, and power management mode. In configuration mode, the module cannot be found / connected, and is always in awake status.
The module has 2 power configurations, common power mode and low energy mode, and factory default is common power mode. In low energy mode, the device will greatly reduce power consumption level. For both modes, there is no difference of power consumption in search, connection and data communication. Only before the user transmits data through UART to the module, user should control awake pin to wake module. And after finish data transmission, user should control awake pin to make module sleep. In parameter configuration mode, the module is always in the common power mode.
The user can decide whether if they need to use low energy mode based on their application. And if the LED indicator is not needed, it can be shut down by parameter configuration, so that the module reaches the lowest power consumption level.

Note1: This refers to the data transfer rate between two modules, which is related to the connection parameters. The test is done when the connection interval is set to 6. If use different mobile phones and modules to transmit data, the speed may different.
Note2&Note3: This value varies with the connection parameters, and different master devices may have different values, such as using different mobile phone connection module, the power consumption of the module is different.
