Other configuration State Instructions LED: P1_2 Model LED Display Status Slave Even slow flash (800ms-on,800ms-off) Waiting for matching Long bright connection 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.
DX-BT05 Bluetooth Module Page 7 of 7 . 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.
