                  Product introduction:

                  The JDY-17 transmission module is based on the Bluetooth 4.2 protocol standard, the working band is 2. 4GHZ range, the modulation mode is GFSK,  the maximum transmission power is Odb, the maximum launch distance is 60 meters. The import original chip is designed to support the user to modify the equipment name, service UUID, transmit power, match the password and so on through the AT command. Czechoslovakia is flexible.
                  JDY-17 Bluetooth module can realize data transmission of module and cell phone or module and module, and can choose UART or IIC communication mode through I0, and BLE Bluetooth can be used for product application quickly through simple configuration.

                  Working mode Broadcast state Current Remark
                  Awaken Broadcast 4. 9mA Generally speaking with APP, it is  suggested that broadcasting should not be too long and too long to affect connection time. It is generally recommended between 100 and 500mS, such as fast connection and no demand for power consumption. The broadcast interv al can be set to the  shortest possible.

                  SELECT boot for low power, this pin function is IIC DC
                  21 SELECT UART or IIC selection pin
                  Open low level: IIC communication mode
                  Open high level: UART communication mode
                  The default SELECT is suspended to high level: UART communication mode. When the user needs IIC, the SELECT pin should be grounded.
                  22 PWRC Down wake-up, when the AT command needs to be sent in the  connection state, the AT instruction mode can be expressed by keeing this pin low level, and the pin is AT instruction mode at high and low levels in the unconnected state.
