after the wake-up signal, and the host computer needs to write to the serial port within this time. command or
transparently transmit data. At present, there are the following 3 ways to realize serial wake-up in low power
mode.
3.2.1 delay method
Send a serial port command to the sleep node, first send a single byte of 0x00, and then send a HEX
command or AT command or a transparent message within 1ms~200ms.
3.2.2 continuous click
This method is suitable for manually operating the upper computer to send HEX commands or AT commands
to the dormant node. First operate the host computer to send a command to the module, this command is used to
wake up the module, but the command is not received completely and the module receives an error command. It
then needs to issue a second command to the sleep module within 200 milliseconds. This method is not suitable for
transparent data transmission, because there is no error detection for transparent data transmission, which will
cause wrong data packets to be sent out.
3.2.3 insertion method
This method is suitable for HEX command mode, AT command mode, and data transparent transmission
mode. Insert several bytes of 0x00 before the command or data to wake up the serial port. The number of 0x00
inserted is determined by the serial port baud rate, and the accumulated baud rate is 0.5ms. Because the RX starts
to take effect 0.5ms after the module wakes up, if it is in AT mode or transparent transmission mode, neither more
nor less 0x00 can be inserted.
3.3 ZCL Standard Specification for Modules
The E180-ZG120A/B module has 4 APS layer ports. Port 1 is for transparent transmission control, and ports 2, 3,
and 4 are for PWM output control. The specifications are as follows.
Because professional, so choose!
WiFi, Bluetooth, Zigbee, PKE, digital radio, etc.
