LX Serial Data Format T2

Simple packet and protocols easy to use. UART, Bluetooth, WiFi, Ethernet, etc.


  • Extremely simple packet and easy to use.
  • Multi channel real time stream transmission.
  • Different type of Tx and Rx.
  • LXSDF T2 can be used with embedded UART(RS-232), Bluetooth, WiFi, Ethernet, etc.
  • COM port auto search. ( Automatic detecting the device to communicate.)


LXSDF T2 is a general purpose serial communication standard which is able to transmit the real-time multi channel stream data and the low speed data in one packet. A typical example of multi channel stream is the time series data converted by the multi channel ADC(Analog to Digital Converter). T2 can be used in any serial communication system using UART (Universal Asynchronous Receiver & Transmitter), windows PC’s com port, android host’s serial port , wifi, bluetooth and ethernet  etc.

UART(com port, serial port) is the most commonly used serial communication. UART can transmit one byte sequentially, but it rarely happens that sends only one byte of data element needed in Communication in real applied process. For example, when transmitting 12 bit AD converted data,  must transmit serial communication 2 bytes dividing  4 bits and 8 bits and unify them into one 12bits data in receiver. If there are various kinds of data to transmit, it is in need of  packet concept. LXSDF T2 can handle several bytes as one packet, transmitting and receiving sides use the data by separating according to the standard LXSDF T2.

As the following picture, the left side is device and the right side is host. In general, the devices have many cases that they transmit a lot of data to the host side, while the host side has the cases that they usually transmit simple orders.  The data type transmitting from device to host (receiving from device as host) is named LXSDF T2 Tx  and  the data type receiving  from host to device is named  LXSDF T2 Rx.
