Function description

5.1 Fixed transmission 5.2 Broadcasting transmission 5.3 Broadcasting address

• For example: Set the address of module A as 0xFFFF or 0x0000, and the channel as 0x04;
• When module is the transmitter (transparent transmission), all modules under channel 0x04 will receive the data, the purpose of broadcast is realized.

5.4 Monitor address

• For example: Set the address of module A as 0xFFFF or 0x0000, and the channel as 0x04;
• When module A is the receiver, it can receive the data sent from all modules under channel 0x04, the purpose of monitor is realized.

5.5 Reset

When the module is powered, AUX outputs low level immediately, conducts hardware self-check and sets the operating mode based on user’s parameters. During the process, the AUX remains low level. After the process completed, the AUX outputs high level and starts to work as per the operating mode combined by M1 and M0. Therefore, users need to wait the AUX rising edge as the start of module’s normal work.
5.6 AUX description

• AUX Pin can be used as indication for wireless send & receive buffer and self-check.
• It can indicate whether there are data that are not sent yet via wireless way, or whether all wireless data has been sent through UART, or whether the module is still in the process of self-check initialization.

5.6.1 Indication of UART output

• To wake up external MCU

5.6.2 Indication of wireless transmitting
Buffer (empty): the internal 1000 bytes data in the buffer are written to the RFIC (Auto sub-packaging). When AUX=1, the user can input data less than 1000 bytes continuously without overflow. Buffer (not empty): when AUX=0, the internal 1000 bytes data in the buffer have not been written to the RFIC completely. If the user starts to transmit data at this circumstance, it may cause overtime when the module is waiting for the user data, or transmitting wireless sub package. When AUX = 1, it does not mean that all the UART data of the module have been transmitted already, perhaps the last packet of data is still in transmission. 5.6.3 Configuration procedure of module

• Only happened when power-on resetting or exiting sleep mode

to the one with low level output, which means if it meets each of any low level output condition, AUX outputs low level, if none of the low level condition is met, AUX outputs high level.
2| When AUX outputs low level, it means the module is busy & cannot conduct operating mode checking. Within 1ms since AUX outputs high level, the mode switch will be completed.
3| After switching to new operating mode, it will not work in the new mode immediately until AUX rising edge lasts for 2ms. If AUX stays on the high level, the operating mode switch can be effected immediately.
4| When the user switches to other operating modes from mode 3 (sleep mode) or it’s still in reset process, the module will reset user parameters, during which AUX outputs low level.

Operating mode

There are four operating modes, which are set by M1 and M0, the details are as follows: Mode(0-3)| M1| M0| Description| Remark
---|---|---|---|---
0 Normal mode| 0| 0| UART and wireless channel are open, transparent transmission is on| Supports configuration over air via special command
1 WOR mode| 0| 1| Can be defined as WOR transmitter and WOR receiver| Supports wake up over air
2 Configuration mode| 1| 0| Users can access the register through the serial port to control the working state of the module|
3 Deep sleep mode| 1| 1| Sleep mode|

6.1 Mode switching

operating mode. Two GPIOs of the MCU can be used to control mode switching;
• After changing M1 and M0: If the module is idle, after 1ms, it can start working according to the new mode;
• If the serial port data of the module has not been transmitted through the wireless, the new working mode can be switched after the transmission is completed;
• If the module receives the wireless data and transmits the data through the serial port, it needs to finish transmission before switching the new working mode;
• Therefore, mode switching can only be valid when AUX output is 1, otherwise it will delay switching.
---|---
2| • For example, users continuously inputs a large amount of data and simultaneously performs mode switching. At this time, the switching mode operation is invalid; the module will process all the user data before performing the new mode detection;
• Therefore, the general recommendation is to detect the output state of the AUX pin and switch after 2ms when the output is high.
3| • When the module is switched from other modes to sleep mode, if the data has not been processed yet;
• The module will process these data (including receiving and sending) before entering sleep mode. This feature can be used for fast sleep, which saves power; for example, the transmitter module works in mode 0, the user transmits the serial port data “12345”, and then does not have to wait for the AUX pin to be idle (high level), and can directly switch to sleep mode. And the user’s main MCU immediately sleeps, the module will automatically transmit the user data through the wireless, and automatically enters sleep within 1ms;
• This saves MCU’s working time and reduces power consumption.
4| • Similarly, any mode switching can use this feature. After the module processes the current mode event, it will automatically enter the new mode within 1ms; thus eliminating the need for the user to query AUX and achieve the purpose of fast switching;
• For example, switching from the transmit mode to the receive mode; the user MCU can also enter sleep before the mode switch, and use the external interrupt function to acquire the AUX change, thereby performing mode switching.
5| • This operation mode is very flexible and efficient, and is designed according to the user’s MCU’s operation convenience, and can reduce the workload of the entire system as much as possible, improve system efficiency, and reduce power consumption.

• The module recognizes the first three bytes of the serial data as: address high + address low + channel and takes it as the wireless transmitting target.
• After the reply function is enabled, if the target address is not the module itself, the module will forward it once.• In order to prevent data return- back, it is recommended to use it in conjunction with the fixed point mode. That is: the target address is different from the source address.
• When enabled, wireless data will be monitored before it is transmitted, which can avoid interference to a certain extent, but may cause data delay.
• Valid only for mode 1.
• After the WOR receiver receives the wireless data and outputs it through the serial port, it will wait for 1000ms before entering the WOR again. Users can input the serial port data and return it via the wireless during this period. Each serial byte will be refreshed for 1000ms. Users must transmit the first byte within 1000ms.
• Valid only for mode 1.
• Period T = (1 + WOR) 500ms, maximum 4000ms, minimum 500ms
• The longer the WOR monitoring interval period, the lower the average power consumption, but the greater the data delay
• Both the transmitter and the receiver must be the same (very important).

Repeater networking mode

and the repeater starts working.
2| In the repeater mode, ADDH, ADDL are no longer used as the module address, but is correspondingly paired with the NETID. If the data of one of the networks is received, it is forwarded to another network. The network ID of the repeater itself is invalid.
3| In repeater mode, the repeater module cannot transmit and receive data, and cannot perform low-power operation.
4| The user enters the other mode from mode 3 (sleep mode) or during the reset process, the module resets the user parameters during which the AUX outputs low level.

Repeater networking rules:

1. Forwarding rules, the repeater can forward data in both directions between two NETIDs.
2. In repeater mode, ADDH\ADDL is no longer used as the module address, and it is used as a NETID forwarding pairing flag.

Figure:

1. Primary repeater
   “Node 1” NETID is 08.
   “Node 2” NETID is 33.
   Primary repeater 1‘s ’ADDH\ADDL are 08，33.
   So the signal sent by node 1 (08) can be forwarded to node 2 (33)
   At the same time, node 1 and node 2 have the same address, so the data transmitted by node 1 can be received by node 2.

2. Secondary repeater
   Secondary repeater’s ADDH\ADDL are 33，05.
   Therefore, Repeater 2 can forward the data of Repeater 1 to the network NETID:

3. Thus node 3 and node 4 can receive node 1 data. Node 4 outputs data normally, and node 3 has a different address than node 1, so no data is output.

4. Two-way repeater
   As shown in the figure: the data sent by node 1, the nodes 2, 4 can receive the data sent by node 2, 4, and node 1 can also receive it.

Configuration instructions on computer

• The following figure shows the E22-230T22S configuration host computer display interface, the user can switch to the command mode through M0M1, and quickly configure and read the parameters on computer.
  

• In the configuration on computer, the module address, frequency channel, network ID, and key are all in decimal mode. The range of values of each parameter is:
  Network address: 0-65535
  Frequency channel: 0-64
  Network ID: 0-255

• When the user configures the repeater mode using the host computer, special attention must be paid. Since the parameters are in decimal mode in the host computer, the module address and network ID need to be converted into hexadecimal. For example, if the network ID input by the transmitting end A is 02, and the network ID input by the receiving end B is 10, when the repeater end R sets the module address, the hexadecimal value 0X020A is converted into the decimal value 522 as the repeater end R. Module address. That is, the module address value of the repeater terminal R is 522 at this time.

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；
• 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.

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 in right range, voltage higher than maximum value 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;
