Wireless digital transmission module X616

The X616 is a wireless transmission module that operates in the ism band or national metering band; it uses customised communication frequencies and its chip, the sx1278, uses "lora" direct sequence spreading technology to outperform existing gfsk modules in terms of stability, anti-interference capability and reception sensitivity. The module operates in the 410-510mhz frequency band, without changing any user data or protocols, and uses a half-duplex transparent transmission mechanism to achieve the function of wireless substitution, lowering the threshold of wireless applications. It has the advantages of concentrated power density, long transmission distance and strong anti-interference capability. The lora direct sequence spread spectrum technology will bring even longer distances. The module has a software fec forward error correction algorithm, which has high coding efficiency and strong error correction capability, and can actively correct the interfered packets in case of sudden interference, greatly improving reliability and transmission distance. In the absence of fec, such packets can only be discarded. The module has data encryption and compression capabilities. The data transmitted by the module over the air, which is random in nature, is rendered meaningless by tight encryption and decryption algorithms that make data interception meaningless. The data compression function has the potential to reduce transmission times and reduce the probability of interference, increasing reliability and transmission efficiency. The module can operate from 2.3 - 12v to meet battery power requirements. The module has four operating modes, which can be switched freely during operation. In power saving mode, the current consumption is only a few tens of ua, making it ideal for ultra-low power applications.

Caution:
1. Wireless module sle is the hardware hibernation console, when it is suspended or high, the module is in normal working state, when it is low, the module is in hibernation state.
2. wireless module ch is the channel switching console, ch foot overhang or high level, the module channel in the factory default, low level trigger into the channel state, trigger the foot channel (1 ~ 8) can be cyclic switching, ch foot long press more than 3 seconds channel to restore the factory default state 5 channels. Channel switching when the module needs to be in standby mode (not recommended when working normally)
3. Laptop usb interface and module connected, need to pass usb to ttl/rs232/rs485 module in order to communicate.
4. Desktop computers basically come with their own com terminal, whose standard is the rs232 interface, and the rs232 interface module can be connected directly, such as the interface is ttl/rs485 will need to be converted to the appropriate level in order to communicate.

Product working modes

Description of the module normal operation indicator

The wireless digital module has 2 led working indicators, the red light will flash twice when power is applied; the red light will be on when transmitting data and the green light will be on when receiving data

Hibernation mode of operation of the module
1. Conventional mode

In a normal operating state, the user device just sends data to the serial port of the module and the module can send data to the air normally. It can also receive data over the air and output it to the serial port with an operating current of <30ma.

2. Serial port sleep mode

When data is received on the serial port of the module, the module is able to send and receive data normally. It can also receive data over the air and output to the serial port. The operating current is <16ma

3. Hardware hibernation mode

The module cannot send data or receive data over the air when the sle pin is left open or high, if you want to send and receive data, enable sle to be low and switch to the regular module. The module will receive the module 10ms after enabling. The operating current is <1ua.

4. Air hibernation mode

The duty cycle can be set at the customer's request.
