JDY-18 High Speed Transparent Transmission Bluetooth Module Technical support QQ: 3411947569 email: 3411947569@qq.com Working current Description of JDY-18 sleep mode Sleep mode Instructions Function description Sleep mode 0 AT+STARTEN0 Mode 0 ：Wake up, users need sleep can be controlled by AT+SLEEP command, wake up can be controlled by PWRC pin wake-up. Sleep mode 1 AT+STARTEN1 Mode 1：Boot sleep, wake up after the connection, disconnect automatically into sleep, note: AT+SLEEP invalid mode 1, sleep controls sleep by Bluetooth module itself. Working mode Broadcast state current Remarks Wake up Broadcast 4mA Generally communicate with APP connection, which is suggested that broadcast should not set too long, for which will affect the connection time. The broadcast interval is generally recommended to be set between 100 to 500mS. If you need to connect fast and with no power requirement, the broadcast intervals can be set to the shortest. Deep no broadcast sleep No broadcast 1.38uA Light sleep broadcast 100mS broadcast interval 280uA Average power consumption 200mS broadcast interval 110uA 300mS broadcast interval 30uA 400mS broadcast interval The following currents are much lower 500mS broadcast interval 600mS broadcast interval 700mS broadcast interval 800mS broadcast interval 900mS broadcast interval 1000mS broadcast interval Wake up state Connected 4mA In connection state, the PWRC pin can be pulled down to send the AT command or directly set the operation mode, you can check the AT+STARTEN instruction. Sleep state Connected 50uA
JDY-18 High Speed Transparent Transmission Bluetooth Module Technical support QQ: 3411947569 email: 3411947569@qq.com FAQ Questions Question answer 1：How does MCU disconnect Bluetooth connection under connection state? In the connection state, the PWRC pin is pulled down, and the serial port sends AT+DISC to disconnect the connection IIC can disconnect the memory address: 0X15 writes 0X01 values to indicate disconnection 2：Can it write data to the module if the connection password is incorrect? No, it can’t. Only the correct password can write data to the module 3：How much data can the serial port write at one time? No byte limit, 100K can be sent once (master slave communication) 4：How fast can the fastest communication rate be reached? With mobile phone measured 8K Bytes per second, module master slave communication can achieve 115200 baud rate continuous transceiver, and the rate of 115200bps. 5：After configuring parameters by serial port or IIC, does it need to be restarted to take effect? It is recommended to restart when the module parameters are set. 6：Parameters of serial port or IIC configuration, is the power up stored next time? After saving, configuring, the next power up is the last configuration parameter. 7：How to test the deep sleep current of test module? It is recommended to connect the VCC and GND pins to test current.
