1. Overview
E70-915NW14S is the star network module, operating at
915MHz, based on originally imported TI CC1310 and
15.4-Stack protocol, with coordinator and terminal as a whole.
There are long range, standard range and high-speed
transmission modes. Maximum 200 nodes can send data to
one coordinator. Use industry-standard AT commands for
operating configuration, which greatly simplifies user
operations.
E70-915NW14S is the first 915MHz wireless module
that solves a series of problems caused by traditional modules. Users will spend less effort to deal with complex network
protocols, which greatly reduces the difficulty of customer development and shortens the user's development period. The
protocol guarantees the stability and packet rate of the entire wireless communication system.
E70-915NW14S strictly follows design standards of FCC, CE, CCC and meets various RF certification
requirements for exporting.

● When designing the power supply circuit for the module,
it is often recommended to reserve more than 30% of the
margin, as the whole machine is conducive to long-term
stable work;
● The current required for the instant of launch is large but
often because the transmission time is extremely short, the
total energy consumed may be smaller;
● When customers use an external antenna, the degree of
impedance matching between the antenna and the module
at different frequency points will affect the magnitude of
the transmit current to varying degrees.

plurality of LRC components are used in the entire RF loop,
there is a case where error accumulation occurs, resulting in
a difference in transmission current of different modules;
● Reducing the transmit power can reduce power
consumption to some extent, but reducing the transmit

6.2 LINK description
The LINK pin indicates the current network status, after the node is connected to the network, the current pin is
pulled low. The external device can query the device network status through the pin level. In the coordinator mode, the
pin indicates if the module establishes the network normally.
6.3 ACK description
The ACK pin is used to indicate the status of the last user’s data transmission. Before transmitting, the pin is pulled
low. After the transmission is successful, the pin is pulled high. Users can use this pin state to judge if the data has
arrived successfully. This pin function cannot indicate the coordinator to send broadcast message.
Note: In 802.15.4 protocol, the device will use the CSMA/MA technology to access the channel before sending data.
When the receiving device receives the data, the returned ACK does not have this mechanism. This means that even if
the receiving device can receive data in extreme conditions, sending device ACK pin indicates that the last data
transmission failed.
7. Operating mode
7.1 Coordinator mode
If users configure the operating mode as 4,（M0=0,M1=0）or users configure the operating mode as 0, the module
works in the coordinator mode. In the coordinator mode, the coordinator can set up the network, coordinator is the
central node of the network, there must be a coordinator in the network.
The coordinator configurable data input mode is:
Broadcast transmission. When configured to broadcast, all non-dormant devices on the entire network will receive
data. The ACK pin indicates transmission successfully all the time.
Short address transmission, when configured to short address transmission, the user must specify the short address
before sending data.

Long address transmission. When configured to long address transmission, the user must specify the long address
before sending data.
7.2 Normal node
If users configure the operating mode 4, （M0=0,M1=1）or users configure the operating mode as 1, the module
works in the normal node mode. In the normal node mode, the data can be received and sent in real time. It is suitable for
application with low power consumption but high real-time requirement.
7.3 Dormant node
If the user configures the operating mode as 4, M0=1,M1=0, or the user configures the operating mode as 2, the
module works in the dormant node mode, the device request if there is data transmitted by coordinator according to the
user-configured sleep period , The non-broadcast data sent by the coordinator will be temporarily stored inside the
coordinator. The device is in low power consumption during the sleep period. If the sleep node wants to send data
actively, the user should send no more than two bytes to wake up the device. After the byte data is used to wake up the
device and the wake-up byte is sent, the user needs to wait for more than 100ms to send the real data. After the wake-up
byte is sent, the user needs to wait for 100ms to send the real data and the wake-up data will be discarded. After the
device was waken up, the module will open the serial port, receiving AT command, if more than 2 seconds, there is no
data input, the module will close serial port and go to sleep.The sleep node is suitable for applications where the user
requires high power consumption but does not require high real-time data. The input transmission format of the
coordinator cannot be broadcast mode when sending data to the sleeping node , instead, the AT + TFICFG = Value
command should be used to configure its input mode to short address or long address mode. Then Communicate with the
sleeping node according to the usage of this AT command.
7.4 Configuration mode
When M0=1,M1=1,the device will switch to configuration mode. In the this mode, the serial port parameters are:
115200, 8N1, and the average operating current is 4uA. In this mode, the module cannot send and receive data. When the
external AT instruction is configured, needs the serial port to send no more than two bytes data to wake up the
device .After the wake-up byte is sent, the user needs to wait for 100ms to send the real data and the wake-up data will be
discarded. After the device was waken up, the module will open the serial port, receiving AT command, if more than 2
seconds, there is no data input, the module will close serial port and go to sleep. The next AT command requires the user
to resend the wake-up byte.
7.5 Mode switching
No
Remarks
