Low power

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

Copyright ©2012–2019，成都亿佰特电子科技有限公司 2-7
is particularly large, in order to improve the data reception efficiency of the center, the number of network centers can be
increased, that is, multiple central devices with the same network ID number are set, and each central device can be
responsible for completing part of the node data receive.
5.3 center
After receiving the node data, the center E107-SC01-G will output the data through the serial port, including the effective
length of the data, the node device address, the node wireless signal strength, and the effective data. The data packet
format is as follows.

5.4 Node
Before sending data to the center through node E107-SC01-N, you need to first ensure that the node is in normal mode.
In sleep mode, the WKP input remains low, and the system enters normal mode after about 100 milliseconds. The data
transmission format is as follows.

Payload
After the node initiates the data transmission, it needs to wait for the handshake response from the center. If the
transmission timed out, the node will automatically resend it. During data transmission, AUX will keep low level and
output high level after successful transmission.
After the node initiates data transmission, before the successful transmission, that is, AUX remains low, and goes to sleep
through the WKP high level, wireless data transmission will not be affected.

7. Hardware Design
It is recommended to use DC stabilized power supply to supply power to the module. The power supply ripple
coefficient is as small as possible, and the module needs to be reliably grounded.
Please pay attention to the correct connection of the positive and negative poles of the power supply. If the reverse
connection is connected, the module may be permanently damaged.
Please check the power supply to ensure that between the recommended supply voltage, if exceeding the maximum,
the module will be permanently damaged.
Please check the stability of the power supply, the voltage can not be significantly frequent.
When designing the power supply circuit for the module, it is often recommended to reserve more than 30% of the
margin, and the whole machine is beneficial for long-term stable operation.
The module should be as far away as possible from the power supply, transformers, high-frequency wiring and other
parts with large electromagnetic interference.
High-frequency digital traces, high-frequency analog traces, and power traces must be avoided under the module. If
it is necessary to pass through the module, assume that the module is soldered to the Top Layer, and the copper is
spread on the Top Layer of the module contact part(All copper-covered and well grounded), and must be close to
the digital part of the module and routed in the Bottom Layer.
Assuming the module is soldered or placed in the Top Layer, it is also wrong to randomly route the Bottom Layer or
other layers, which will affect the module's spurs and receiving sensitivity to varying degrees.
Assuming that there are devices with large electromagnetic interference around the module, the performance of the

Chengdu Ebyte Electronic Technology Co., Ltd E107-SC01User manual
Copyright ©2012–2019，成都亿佰特电子科技有限公司 7-10
module will also be greatly affected. According to the intensity of the interference, it is suggested to stay away from
the module appropriately. If circumstances permit, appropriate isolation and shielding can be done.
Assume that there are traces with large electromagnetic interference around the module (high-frequency digital,
high-frequency analog, power trace), which will greatly affect the performance of the module. It is recommended to
stay away from the module according to the strength of the interference. If necessary, appropriate isolation and
shielding can be done;
If the communication line uses a 5V level, a 1k-5.1k resistor must be connected in series (not recommended, there is
still a risk of damage).
Try to stay away from some physical layers and also have a 2.4GHz TTL protocol, for example: USB3.0.
The antenna mounting structure has a great influence on the performance of the module. It is necessary to ensure
that the antenna is exposed, preferably vertically upward. When the module is mounted inside the case, use a good
antenna extension cable to extend the antenna to the outside of the case.
The antenna must not be installed inside the metal case, which will greatly reduce the transmission distance.
8. FAQ
8.1 Communication range is too short
The communication distance will be affected when obstacle exists.
Data lose rate will be affected by temperature, humidity and co-channel interference.
The ground will absorb and reflect wireless radio wave, so the performance will be poor when testing near ground.
Sea water has great ability in absorbing wireless radio wave, so performance will be poor when testing near the sea.
The signal will be affected when the antenna is near metal object or put in a metal case.
Power register was set incorrectly, air data rate is set as too high (the higher the air data rate, the shorter the
distance).
When the power supply at room temperature is lower than the recommended low voltage, the lower the voltage is,
the lower the transmitting power is.
Due to antenna quality or poor matching between antenna and module.
8.2 Module is easy to damage
Please check the power supply and ensure it is within the recommended range. Voltage higher than the peak will
lead to a permanent damage to the module.
Please check the stability of power supply and ensure the voltage not to fluctuate too much.
Please make sure anti-static measures are taken when installing and using, high frequency devices have electrostatic
susceptibility.
Please ensure the humidity is within limited range for some parts are sensitive to humidity.
Please avoid using modules under too high or too low temperature.

8.3 High bit error rate
There are co-channel signal interference nearby, keep away from interference sources or modify frequency, channel
to avoid interference.
Unsatisfactory power supply may also cause garbled characters, and ensure the reliability of the power supply.
If the extension cable or feeder is of poor quality or too long, the bit error rate will be high.
