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. The user 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 the user configures the operating mode 4,（M0=0,M1=0）or the user configures 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

Chengdu Ebyte Electronic Technology Co,;Ltd E70-433NW30S user manual

No

Remarks

1

The user can decide the operating mode by the combination of M1 and M0

2

In any work mode, the user can configure the operating mode through the AT command

3

When M0=1,M1=1, the serial port parameters are 115200, 8N1(fixed)

sending data.

7.2.Normal node

If the user configures the operating mode 4, （M0=0,M1=1）or the user configures 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 userconfigured 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 wakeup 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.

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 2uA. 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.

When the configuration is complete, the coordinator restarts and the DIO11 pin is asserted low, indicating that the coordinator has started and is running. After an normal node device starts up, it will have a network access time of 10 to 20 seconds. When the network access is completed, the DIO11 pin will be set to low level, indicating that the network access is successful. After waiting for the device to access the network successfully, the coordinator enters to AT mode, enters the command "AT+DINFO=ALLNODE" with a newline character, the coordinator will return the short address and long address of all the nodes that have already entered the network and recorded. As shown in Figure 5-7:

AT+TLCFG Setting/Querying the concurrency performance parameter (reboot valid)

AT+TLCFG=？

Description: Gets the concurrency performance parameter

Response： TLCFG:0

AT+TLCFG=value

Description: Value:0~3 0：Low concurrency

1：Medium concurrency 2：High concurrency 3：Highest concurrency

Example: AT+ TLCFG =0 (Note: This parameter is mainly used to configure the concurrency performance of the module. That is, when various nodes concurrently transmit

data, the maximum number of nodes is supported. The higher the performance, the greater the number of concurrent systems, but the delay in sending data. The average power consumption of the nodes will increase; the lower the performance, the higher the real-time performance of the data sent by the nodes, but the data may be lost when the environment has large interference or multiple nodes transmit simultaneously.)

10. Hardware design

 It is recommended to use a DC stabilized power supply. The power supply ripple factor 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. Reverse

connection may cause permanent damage to the module；

 Please check the power supply to ensure it is within the recommended voltage otherwise when it exceeds the

maximum value the module will be permanently damaged；

 Please check the stability of the power supply, the voltage can not be fluctuated frequently；

Chengdu Ebyte Electronic Technology Co,;Ltd E70-433NW30S user manual

 When designing the power supply circuit for the module, it is often recommended to reserve more than 30% of the

margin, so 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 routing, high-frequency analog routing, and power routing 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(well grounded), it must be close to the digital part of the module and routed in the Bottom Layer；

 Assuming the module is soldered or placed over the Top Layer, it is wrong to randomly route over the Bottom Layer

or other layers, which will affect the module's spurs and receiving sensitivity to varying degrees；

 It is assumed that there are devices with large electromagnetic interference around the module that will greatly affect

the performance. It is recommended to keep them away from the module according to the strength of the interference. If necessary, appropriate isolation and shielding can be done；

 Assume that there are traces with large electromagnetic interference (high-frequency digital, high-frequency analog,

power traces) around the module that 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 such as TTL protocol at 2.4GHz , for example: USB3.0；  The mounting structure of antenna 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；

 The antenna must not be installed inside the metal case, which will cause the transmission distance to be greatly

weakened.

11 FAQ

11.1 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).

 The power supply low voltage under room temperature is lower than 2.5V, the lower the voltage, the lower the

transmitting power.

 Due to antenna quality or poor matching between antenna and module.

11.2 Module is easy to damage

 Please check the power supply source, ensure it is 2.0V~3.6V, voltage higher than 3.6V will damage the module.  Please check the stability of power source, the voltage cannot fluctuate too much.  Please make sure antistatic measure are taken when installing and using, high frequency devices have electrostatic

susceptibility.

 Please ensure the humidity is within limited range, some parts are sensitive to humidity.  Please avoid using modules under too high or too low temperature.

11.3 BER(Bit Error Rate) is high

 There are co-channel signal interference nearby, please be away from interference sources or modify frequency and

channel to avoid interference;

 Poor power supply may cause messy code. Make sure that the power supply is reliable.  The extension line and feeder quality are poor or too long, so the bit error rate is high;
