5 Operating mode

5.1 Low power mode

In any case, Pin P06 input high enters sleep mode and reduces the whole power consumption. Now the serial port stops receiving
any data while the transparent transmission of the Bluetooth remains unaffected. In this mode the output function of the serial port is
still valid and data received in Bluetooth port can output via serial port.
Description:
1) If Bluetooth is connected, after entering the low power mode, you can command <BKTOSLPON>/<BKTOSLPOFF > to select
whether to disconnect the current connection. This function can be used to quickly disconnect the Bluetooth connection and enter the
low power mode after the external MCU is sent and received.

Input power
Module inputted a high level enters hardware reset state
and module inputted a low level come back to normal
operating state, which is used for restoration in emergency
-
To indicate connection state of Bluetooth, when connected
the pin output a low level; when interrupted the pin output a
high level.
-
To configure the role of the module and it is a slave when a
high level is inputted and it is a master when a low level is
inputted. (It contains internal pull-up resistance and
operates as a slave by default. See more on 5.5 Role
