Module dormancy set
Is only meaningful in from dormancy mode module, from the mode via a serial port
to send "AT + SLEEP", if no accident, the module will return "OK" and enter a
dormant state, this state to be found and connection status.
Wake up the module Settings
There are two ways:
Method one: you can send the length of the string is greater than or equal to 80 to
activate the module. Send the activated string cannot contain the AT command,
success after WAKE up, a serial port will output "+ WAKE OK" string.
Method 2: short press the system button SW1.

System key SW1(P1_3)
P1_3 for input pin, short press control, can realize the following functions:
1, the module is in a state of dormancy:
Module will be awakened to the normal state, the success after WAKE up, a serial
port will output "+ WAKE OK" string.
2, the module is in a state of connection:
Disconnected module will initiate the request.
10.Layout Announcements
1, DX-BT05 bluetooth module serial level should be 3.3 V, if the connection and
5V level system need to increase the level conversion chip.
2, Bluetooth signal is highly affected by the surrounding,such as trees, metal, wall can
have certain absorption on the bluetooth signal or block, so the installation is not
recommended in the metal case.
3, Due to metal will weaken the function of antenna, it is suggested that Lay in the
module board, don't lay GND and a line under the antenna module, it is best to hollow
out.
