n
N series: The module delays 200 milliseconds after power-on, and starts to detect the WKP pin
status. If a high level is detected, the system immediately goes to sleep. During this period, the
serial port cannot receive data and there is no RF transceiver operation. When the falling edge
of WKP hardware is detected, it will exit low-power mode. Note that the WKP pin has an input
level latch function. When a rising edge is detected, the internal pin is pulled up to enable the
pin to maintain a high state, otherwise after the falling edge is input, the internal pin is pulled
down to maintain the low status.
G series: invalid

Ordinary
N series: The module is delayed by 200 milliseconds after power-up is completed, and the
WKP pin status is detected. If a low level is detected, the system enters the normal working
state, the serial port function is enabled, and data or configuration commands can be sent, and
the wireless function is valid.
G series: Always keep this state awake, the wireless receiving function is turned on, and the
serial port prints out wireless data packets.
Special note: N series modules in normal mode, if data transmission is started, before a successful transmission (AUX
output low level) can be switched to low power mode through the WKP pin, system power consumption is reduced
compared to normal mode, but wireless Data transmission is not affected, and the system power consumption will
return to normal after the data transmission is completed.
5. Features Introduction
5.1 Network model
The E107-SC01 series of products, working under the star network structure, are composed of two parts: the center
E107-SC01-G and the node E107-SC01-N. There must be at least one center in a network responsible for centralized data
collection. There can be multiple nodes. In principle, the number of nodes in a network is not limited. In the open
environment, the maximum communication distance between the node and the center exceeds 100 meters.
The node sends data asynchronously. The host notifies the slave of the successful reception through a handshake
signal. If the node does not receive the notification message from the center in time, it will automatically start data
retransmission. At this time, the center will receive duplicate data packets.
5.2 Network ID
The network ID is used for logical network division. The center can only receive the network ID data. The network
IDs of the nodes and the center can be configured by instructions. In particular, when the number of nodes in the network
