E220-400T30S User manual 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. 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 5.4 Monitor address monitor is realized. 5.5 Reset 5.6 AUX description 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. 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 Copyright 20122018Chengdu Ebyte Electronic Technology Co.,Ltd. 10 Chengdu Ebyte Electronic Technology Co., Ltd. E220-400T30S User manual 5.6.2 Indication of wireless transmitting Buffer (empty): the internal 256 bytes data in the buffer are written to the RFIC (Auto sub-packaging). When AUX=1, the user can input data less than 256 bytes continuously without overflow. Buffer (not empty): when AUX=0, the internal 256 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 5.6.4 Notes for AUX 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. Copyright 20122018Chengdu Ebyte Electronic Technology Co.,Ltd. 11 No. 1 2 3 4 5 1 2 3 Chengdu Ebyte Electronic Technology Co., Ltd. E220-400T30S User manual 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. Due to the characteristics of the LoRa modulation method, the information transmission delay is much longer than that of FSK. For example, at 2.4kbps airspeed, the 100-byte transmission delay is about 1.5 seconds. It is recommended that customers do not transmit large amounts of data at low airspeeds, so as to avoid communication abnormalities caused by data loss due to data accumulation. 6 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 UART and wireless channel are open, transparent transmission is on Can be defined as WOR transmitter and WOR receiver Supports wake up over air 0 Normal mode 1 WOR transmitting 2 WOR receiving mode mode 0 0 1 1 0 1 0 1 6.1 Mode switching 3 Deep sleep mode For parameter configuration Only work as WOR receiver
No. Remark Users can combine M1 and M0 with high and low levels to determine the 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. 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. 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. Copyright 20122018Chengdu Ebyte Electronic Technology Co.,Ltd. 12 Chengdu Ebyte Electronic Technology Co., Ltd. E220-400T30S User manual 4 5 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. 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. Transmitting Users can input data through the serial port and the module will start wireless transmission. Receiving The module wireless receiving function is turned on, and after receiving the wireless data, it will be output through the serial port TXD pin. 6.2 Normal modeMode 0 Type M0 = 0M1 = 0 6.3 WOR transmitting modeMode 1 Type M0 = 1M1 =0 Transmitting Wireless data transmitting is enabled Receiving Wireless data receiving is enabled 6.4 WOR receiving modeMode 2 Type M0 = 0M1 = 1 Transmitting Wireless transmitting off Receiving Wireless receiving on Copyright 20122018Chengdu Ebyte Electronic Technology Co.,Ltd. 13 Chengdu Ebyte Electronic Technology Co., Ltd.

Note When from the sleep mode to other modes, the module will reconfigure the parameters. During the configuration process, AUX will remain low; After configuration, it outputs high level, we suggest that user test rising edge T_BUSY.

E220-400T30S User manual 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. 10 FAQ 10.1 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.

The modular transmitter must have its own RF shielding. Answer from applicant Yes The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with Part 15 requirements under conditions of excessive data rates or over-modulation. The modular transmitter must have its own power supply regulation. The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204(b)(c). The antenna must either be permanently attached or employ a unique antenna coupler (at all connections between the module and the antenna, including the cable). The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. 6. The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number in accordance with 15.212 (a)(1)(vi)(A) / (B). 7. The modular transmitter must comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. For example, timing requirements that must be met before a transmitter is authorized for operation under Section 15.231. For instance, data transmission is prohibited, except for operation under Section 15.231(e), in which case there are separate field strength level and timing requirements. Compliance with these requirements must be assured. there are very strict operational and 2. 3. 4. 5. 8. The modular transmitter must comply with any applicable RF exposure requirements. For example, FCC Rules in Sections 1.1310, 2.1091, 2.1093, and specific Sections of Part 15, including 15.319(i), 15.407(f), 15.253(f) and 15.255(g), require that Unlicensed PCS, UNII and millimeter wave devices perform routine environmental evaluation for RF Exposure to demonstrate compliance. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF Exposure compliance. Modular transmitters approved under other Sections of Part 15, when necessary, may also need to address certain RF Exposure concerns, typically by providing specific installation and operating instructions for users, installers and other interested parties to ensure compliance. Yes Yes Yes Yes Yes Yes Yes Items to be covered by Split modular transmitters. 1. The modular transmitter must comply with all requirements of a single modular transmitter except for items (1) & (5) of the above single modular approval requirements. Answer from applicant 2. Only the radio front end must be shielded. The physical crystal and tuning capacitors may be located external to the shielded radio elements. The interface between the split sections of the modular system must be digital with a minimum signalling amplitude of 150 mV peak-to-peak. 3. Control information and other data may be exchanged between the transmitter control elements and radio front end. 4. The sections of a split modular transmitter must be tested installed in a host device(s) similar to that which is representative of the platform(s) intended for use. 5. Manufacturers must ensure that only transmitter control elements and radio front end components that have been approved together are capable of operating together. The transmitter module must not operate unless it has verified that the installed transmitter control elements and radio front end have been authorized together. Manufacturers may use means including, but not limited to, coding in hardware and electronic signatures in software to meet these requirements, and must describe the methods in their application for equipment authorization. Note: A limited modular approval (LMA) may be granted for single or split modular transmitters that comply partially with the requirements above.
