Fired at a fixed point

Broadcast emission 
- အသံလွှင့်လိပ်စာ
- Example: set module A address to 0xFFFF and channel to 0x04.
- When module A is used as a transmitter (same mode, transparent transmission method), all receiving modules under channel 0x04 can receive the data for the purpose of broadcasting.
 
- နားထောင်ရမည့်လိပ်စာ
- Example: set module A address to 0xFFFF and channel to 0x04.
- When module A is used as a receive, it can receive all the data under channel 0x04 to achieve the purpose of listening.
 
- မော်ဂျူးကို ပြန်လည်သတ်မှတ်ပါ။
- After the module is powered on, AUX will immediately output a low level, and carry out hardware self-test, as well as set up the working mode according to user parameters; During this process, AUX will keep low level, and when finished, AUX will output high level, and start to work normally according to the working mode combined by M1 and M0; Therefore, the user needs to wait for the rising edge of AUX as the starting point of normal operation of the module.
 
- AUX in detail
- AUX is used for wireless transceiver buffer indication and self-test indication.
- It indicates whether the module has data that has not yet been transmitted out through the wireless, or whether the wireless data that has already been received has not yet been sent out in full through the serial port, or whether the module is in the process of initializing the self-test.
 
- Serial data output indication
- is used for waking up an external MCU in hibernation;
 

ရေဒီယို ထုတ်လွှင့်မှု ညွှန်ပြချက်
- Buffer Empty: the data in the internal 512 byte buffer are written to the wireless chip (automatic packetization).
- When AUX=1 when the user continuously initiates less than 512 bytes of data, will not overflow. When AUX=0 when the buffer is not empty: the internal 512-byte buffer data, not yet all written to the wireless chip and open the launch, at this time the module may be waiting for the end of the user’s data timeout, or are wireless sub-packet launch.
- [Note]: AUX=1 does not mean that all the serial data of the module have been launched through the wireless, or the last packet of data is being launched.

သတိထားပါ။
| မရှိ | AUX မှတ်စုများ | 
| 1 | For function 1 and function 2 above, the output low level is prioritized, i.e.: when any of the output low level conditions are satisfied, the AUX outputs a low level; When all low level conditions are not satisfied, AUX outputs high level. | 
| 2 | When AUX outputs low level, it indicates that the module is busy, and no working mode detection will be performed at this time; When the module AUX output high level within 1ms, will complete the mode switching work. | 
| 3 | After the user switches to a new operating mode, at least 2ms after the rising edge of AUX is required for the module to actually enter that mode; If AUX stays high, then the mode switching will take effect immediately. | 
| 4 | The module resets the user parameters when the user enters from mode 3 (sleep mode) or during a reset, during which the AUX output goes low. | 
| 5 | Due to the characteristics of LoRa modulation, the information transmission delay is much longer than FSK, such as in 2.4kbps air speed, 100 bytes of transmission delay is about 1.5 seconds, it is recommended that customers do not carry out the transmission of large amounts of data at low air speeds, so as to avoid data loss due to the accumulation of data caused by the communication anomaly. |

| 0 General Mode | 0 | 0 | Serial open, wireless open, transparent transmission | The receiver must be mode 0, 1 | 
| 1 Wake-up mode | 0 | 1 | Serial port open, wireless open; The only difference with mode 0: before the packet is transmitted, the wake-up code is automatically increased so as to wake up the receiver working in mode 2 | Receiver can be mode 0 Receiver can be mode 1 Receiver can be mode 2 | 
| 2 ပါဝါချွေတာ mode ကို | 1 | 0 | Serial port reception is off, wireless is in Wake-on-Air mode, and when wireless data is received, the serial port is opened to send out the data. | Transmitter must be in mode 1 |

General mode (mode 0)
| ရိုက်ပါ။ | When M0 = 0 and M1 = 0, the module operates in mode 0 | 
| transmitter | Module receives user data from the serial port, the module transmits wireless data packet length of 58 bytes, when the amount of data input by the user reaches 58 bytes, the module will start the wireless transmission, at this time, the user can continue to input the data that need to be transmitted; when the user needs to transmit bytes less than 58 bytes, the module waits for the 3 bytes of time, if there is no user data continue to input, it is considered to be the termination of the data, at this time, the module will be all the data packets | 
| through the wireless sent; when the module receives the first user data, will AUX output low level, when the module puts all the data into the RF chip and starts to transmit, AUX output high level; | |
| လက်ခံသူ | The module always turns on the wireless receive function and can receive packets sent from mode 0 and mode 1; After receiving the packet, the module AUX outputs a low level, and after a delay of 5ms, it starts to send out the wireless data through the TXD pin of the serial port, and after all the wireless data are output through the serial port, the module outputs the AUX to a high level. | 
WOR မုဒ် (မုဒ် 1)
| ရိုက်ပါ။ | When M0 = 1 and M1 = 0, the module operates in mode 1 | 
| transmitter | The conditions for the module to start packet transmitting and the AUX function are equivalent to mode 0; the only difference is: the module will automatically add a wake-up code before each packet, and the length of the wake-up code depends on the wake-up time set in the user’s parameter; the wake-up code is intended to be used to wake up the receiver module working in mode 2; so the data transmitted in mode 1 can be received by modes 0, 1 and 2. | 
| လက်ခံသူ | မုဒ် 0 နှင့် ညီမျှသည်။ |

| ရိုက်ပါ။ | When M0 = 0 and M1 = 1, the module operates in mode 2 | 
| transmitter | The module is in hibernation state, the serial port is closed and cannot receive the serial data from the external MCU, so this mode does not have the wireless transmitting function. | 
| 
 
 
 လက်ခံသူ | In Mode 2, the transmitter is required to work in Mode 1; listen to the wake-up code at regular intervals, once a valid wake-up code is received, the module will continue to be in the receiving state and wait for the whole valid packet to be received; then AUX outputs a low level, and after a delay of 5ms, it opens the serial port and sends out the received wireless data through TXD, and after that, it outputs a high level from AUX; the module continues to enter the “sleep – listen” operating state (polling); by setting different wake-up times, the module has different receiving response delays (maximum 2s) and average power consumption (minimum 30u The wireless module continues to enter the “sleep-listening” working state (polling); by setting different wake-up times, the module has different reception response delays (up to 2s) and average power consumption (minimum 30uA); the user needs to achieve a balance between the communication delay time and the average power consumption. |

Serial Port Upgrade Firmware Notes 
If customers need to upgrade the firmware, they need to find the corresponding BIN file provided by the official, and then use the upper computer provided by the official to upgrade the firmware, generally users do not need to upgrade the firmware, please do not use the “AT+IAP” command.
The necessary pins for upgrading must be pinned out (M1, M0, AUX, TXD, RXD, VCC, GND), and then send “AT+IAP” command to enter the upgrade mode in the configuration mode, if you need to exit the IAP upgrade mode, you need to keep powering up and wait for 60 seconds, and the program will be automatically exited, or else it will enter the upgrade mode indefinitely even if it is rebooted. If you need to exit IAP upgrade mode, you need to keep power on and wait for 60 seconds, the program will exit automatically, otherwise, even if you reboot, it will enter upgrade mode indefinitely. After entering the upgrade mode, the baud rate will be automatically switched to 115200 until it exits automatically, during which a log will be output.

- High-frequency digital alignment, high-frequency analog alignment, power supply alignment must be avoided below the module, if you really need to go through the module below, assuming that the module is welded in the Top Layer, the Top Layer in the contact part of the module to lay the ground copper (all paved with copper and a good ground), it must be close to the digital part of the module and alignment in the Bottom Layer;
- Assuming that the module is soldered or placed in the Top Layer, it is also wrong to randomly route the module in the Bottom Layer or any other layer, which will affect the spuriousness of the module as well as the reception sensitivity to varying degrees;
- Assuming that there is a large electromagnetic interference around the module device will also greatly affect the performance of the module, according to the intensity of the interference is recommended to stay away from the module, if the situation permits you can do appropriate isolation and shielding;
- Assume that there is a large electromagnetic interference around the module alignment (high-frequency digital, high-frequency analog, power supply alignment) will also greatly affect the performance of the module, according to the intensity of the interference is recommended to be appropriate away from the module, if the situation permits you can do appropriate isolation and shielding;
- Communication line if you use 5V level, must be connected in series with 1k-5.1k resistor (not recommended, there is still a risk of damage);
- Try to stay away from some TTL protocols where the physical layer is also 2.4GHz, e.g. USB3.0;
- The antenna mounting structure has a big impact on the module performance, make sure the antenna is exposed and preferably vertically upward;
- When the module is installed inside the chassis, use a good quality antenna extension cable to extend the antenna to the outside of the chassis;
- The antenna must not be installed inside the metal shell, which will lead to a great weakening of the transmission distance.

အဆင်မပြေသော ဂီယာအကွာအဝေး
- When there are linear communication barriers, the communication distance will decay accordingly;
- Temperature, humidity, and co-channel interference, which will lead to higher communication packet loss rate;
- The ground absorbs and reflects radio waves, and the test results are poorer near the ground;
- Seawater has a strong ability to absorb radio waves, so the effect of the seaside test is poor;
- အင်တင်နာအနီးရှိ သတ္တုပစ္စည်းများ သို့မဟုတ် သတ္တုခွံတစ်ခုတွင် ထားရှိပါက အချက်ပြမှု လျော့ပါးမှုသည် အလွန်ပြင်းထန်လိမ့်မည်;
- Wrong power register setting, air rate setting is too high (the higher the air rate, the closer the distance);
- အသံအနိမ့်tage of power supply at room temperature is lower than the recommended value, the lower the voltage the lower the hair power;
- The use of antenna and module matching degree is poor or the antenna itself quality problems.
