E32-A user manual 5 Function description 5.1 Fixed transmission 5.2 Broadcasting transmission 5.3 Broadcasting address For example: Set the address of module A as 0xFFFF, and the channel as 0x04;
When module is the transmitter (transparent transmission), all modules under channel 0x04 will receive the data, the 7 Pro-Lite, Inc. E32-A user manual purpose of broadcast is realized. 5.4 Monitor address monitor is realized. 5.5 Reset For example: Set the address of module A as 0xFFFF, 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 When the module is powered, AUX outputs low level immediately, conducts hardware self-check and sets the operating mode based on users 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 modules 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 512 bytes data in the buffer are written to the RFIC (Auto sub-packaging). When AUX=1, the user can input data less than 512 bytes continuously without overflow. Buffer (not empty): when AUX=0, the internal 512 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 8 Pro-Lite, Inc. E32-A user manual When AUX = 1, it does not mean that all the UART data of the module have been transmitted already, perhaps the transmitting wireless sub package. 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 5.6.4 Notes for AUX No. 1 2 3 4 Description For function 1 & function 2 mentioned above, the priority should be given 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. 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. 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. When the user switches to other operating modes from mode 3 (sleep mode) or its still in reset process, the module will reset user parameters, during which AUX outputs low level. 9 Pro-Lite, Inc. E32-A user manual 6 Operating mode 0 Normal 2 wake up 3 power saving 4 sleep 0 1 0 1 0 1 1 6.1 Mode switch There are four operating modes, which are set by M1 and M0, the details are as follows:
Mode0-3 M0 M1 Mode introduction Remark UART and wireless channel are open, transmission is on transparent The receiver must work in mode 0 or mode 1 The receiver could be 0,1 or 2 the only UART and wireless channel are open, difference with mode 0 is that before transmitting data, increasing the wake up code automatically, so that it can awake the receiver under mode 3. UART close, wireless is under air-awaken mode, after receiving data, UART open and send data. transmitter must be mode 1, unable to transmit in this mode. sleep mode, receiving parameter setting command is available. details more specification. on parameter The user can decide the operating mode by the combination of M1 and M0. The two GPIO of MCU can be used to switch mode. After modifying M1 or M0, it will start to work in new mode 1ms later if the module is free. If there are any serial data that are yet to finish wireless transmitting, it will start to work in new mode after the UART transmitting finished. After the module receives the wireless data & transmits the data through serial port, it will start to work in new mode after the transmitting finished. Therefore, the mode-switch is only valid when AUX outputs 1, otherwise it will delay. For example, in mode 0 or mode 1, if the user inputs massive data consecutively and switches operating mode at the same time, the mode-switch operation is invalid. New mode checking can only be started after all the users data process completed. It is recommended to check AUX pin out status and wait 2ms after AUX outputs high level before switching the mode. If the module switches from other modes to stand-by mode, it will work in stand-by mode only after all the remained data process completed. The feature can be used to save power consumption. For example, when the transmitter works in mode 0, after the external MCU transmits data 12345, it can switch to sleep mode immediately without waiting the rising edge of the AUX pin, also the users main MCU will go dormancy immediately. Then the module will transmit all the data through wireless transmission & go dormancy 1ms later automatically, which reduces MCU working time & save power. Likewise, this feature can be used in any mode-switch. The module will start to work in new mode within 1ms after completing present mode task, which enables the user to omit the procedure of AUX inquiry and switch mode swiftly. For example, when switching from transmitting mode to receiving mode, the user MCU can go dormancy before mode-switch, using external interrupt function to get AUX change so that the mode-switch can be realized. This operation is very flexible and efficient. It is totally designed on the basis of the user MCUs convenience, at the 10 Pro-Lite, Inc. E32-A user manual same time the work load and power consumption of the whole system have been reduced and the efficiency of whole system is largely improved. 6.2 Normal mode (mode 0) When M1 = 0 & M0 = 0, module works in mode 0 Transmitting The module can receive the user data via serial port, and transmit wireless data package of 58 bytes. When the data inputted by user is up to 58 byte, the module will start wireless transmission. During which the user can input data continuously for transmission. When the required transmission bytes are less than 58 bytes, the module will wait 3-byte time and treat it as data termination unless continuous data inputted by user. Then the module will transmit all the data through wireless channel. When the module receives the first data packet from user, the AUX outputs low level. After all the data are transmitted into RF chip and transmission start , AUX outputs high level. At this time, it means that the last wireless data package transmission is started, which enables the user to input another 512 bytes continuously. The data package transmitted from the module working in mode 0 can only be received by the module working in mode 0 or 1. Receiving The wireless receiving function of the module is on, the data packet transmitted from the module working in mode 0
& mode 1 can be received. After the data packet is received, the AUX outputs low level, 5ms later the module starts to transmit wireless data through serial port TXD pin. After all the wireless data have been transmitted via serial port, the AUX outputs high level. 6.3 Wake-up mode (mode 1) When M1 = 0 & M0 = 1, module works in mode 1 Transmitting The condition of data packet transmission & AUX function is the same as mode 0. The only difference is that the module will add preamble code before each data packet automatically. The preamble code length depends on the wake-up time set in the user parameters. The purpose of the preamble code is waking up the receiving module works in mode 2. Therefore, the data package transmitted from mode 1 can be received by mode 0, mode1 and mode 2. Receiving The same as that in mode 0. 6.4 Power-saving mode (mode 2) When M1 = 1 & M0 = 0, module works in mode 2 Transmitting UART is closed, the module cannot receive any serial port data from outside MCU. Hence the function of wireless transmission is not available for the module working in this mode. 11 Pro-Lite, Inc. E32-A user manual Receiving In mode 2, it is required the data transmitter works in mode 1. The wireless module monitors the preamble code at regular time. Once it gets the preamble code, it will remain as receiving status and waiting for the completion of receiving the entire valid data package. Then the AUX outputs low level, 5ms later the serial port is open to transmit received wireless data through TXD. Finally, AUX outputs high level after process completed. The wireless module stays in power-saving monitoring working status (polling). By setting different wake-up time, the module will have different receiving response delay (2s in maximum) and average power consumption (30uA in minimum). The user needs to achieve a balance between communication delay time & average power consumption. 6.5 Sleep mode (mode 3) When M1=1, M0=1, module works in mode 3 N/A N/A Transmitting Receiving Parameter setting Notes This mode can be used for parameter setting. It uses serial port 9600 & 8N1 to set module working parameters through specific instruction format. (pls refer to parameters setting for details) When the mode changes from stand-by mode to others, the module will reset its parameters, during which the AUX keeps low level and then outputs high level after reset completed. It is recommended to check the AUX rising edge for user. 7 Command format In sleep modeMode 3M1=1, M0=1, it supports below instructions on list. No.

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 17dBm 14dBm 10dBm 15 Pro-Lite, Inc. E32-A user manual 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. still a risk of damage) If the communication line uses a 5V level, a 1k-5.1k resistor must be connected in series (not recommended, there is 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. 9 FAQ 9.1 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 The power supply low voltage under room temperature is lower than 2.5V, the lower the voltage, the lower the distance). transmitting power. Due to antenna quality or poor matching between antenna and module. 16 Pro-Lite, Inc. E32-A user manual 9.2 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. 9.3 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;
