JDY-22 sleep mode description
Sleep Mode Command Function Description
Power-on wake-up AT+STARTEN1 Mode 1: wake-up after power-on, the user can control the sleep through AT+SLEEP command, and wake-up can be wake-up through PWRC pin low level
Power-on sleep AT+STARTENO mode 0: The power consumption is very low in this mode. The connection call pass-through current is 900uA, and the disconnection current is 200uA (the broadcast interval current can be set as low as 30uA). In this mode, the PWRC leads After the pin wakes up, if the serial port does not send data or is not connected within 10 seconds, it will automatically go to sleep again
FAQ
Questions Answers
1: How does the MS disconnect the Bluetooth connection in the connected state Pull the PWRC pin low in the connected state, and the serial port sends AT+DISC to disconnect the connection
2: What is the current when the module wakes up? The working current of all modes does not exceed 1mA
3: How much data can be written to the serial port at one time There is no byte limit at 9600 baud rate
4: Whether the serial port configuration parameters need to be reworked to take effect? It is recommended to restart after setting the module parameters.
5: How to test the deep sleep current of the test module? It is recommended to connect the VCC and GND pins to test the current
