7.2 Coordinator model

If the user-configured system operating mode is 4 and the M0M1 combination is 01 or the user-configured system mode

is 1, the module works in the normal node mode. In the normal node mode, it can receive and send data in real time,

which is suitable for application scenarios that do not have high requirements for power consumption but require timely

response.

If the user-configured system operating mode is 4 and the M0M1 combination is 10 or the user-configured system mode

is 2, the module will work in low-power node mode, in low-power node mode, the device will wake up regularly

according to the user-configured hibernation period to ask the coordinator whether there is data sent, the coordinator

sends the non-broadcast data will be stored temporarily inside the coordinator, during the hibernation week the system is

in the Low power consumption, if the low-power node wants to send data actively, the user serial port needs to send any

data no more than two bytes to wake up the device, after the wake-up byte is sent, the user needs to wait for more than

100ms to send the real data, and the wake-up data will be discarded, after waking up the device, the module will open the

serial port to receive the user's data, and after receiving, it starts to send the data wirelessly to the coordinator, if it takes

more than 2 seconds, the device serial port has no data input, and no data is sent to the coordinator. If there is no data

input from the device serial port for more than 2 seconds, the module will turn off the serial port and enter into

low-power mode. The low-power node is suitable for applications where users have high requirements for power

consumption but not high requirements for real-time data.

At any moment in any mode, as long as the M0M1 combination is set to 11, the system will switch to configuration mode

3, in configuration mode, the module serial port parameters are: 115200, 8N1. in this mode, the module can not send to

receive data, external AT instructions to configure the module, you need to user serial port to send any no more than two

bytes of data to wake up the device, wake up bytes sent, the user has to After the wake-up byte is sent, the user needs to

wait for more than 100ms to send the real data, the wake-up data will be discarded, after waking up the device, the

module will open the serial port to receive the AT command, if more than 2 seconds, the device serial port has no data

input, the module will close the serial port to enter into hibernation. The next AT command, the user needs to re-send the

wake-up byte
