WisNode-SPI

1.Product introduction

WisNode-SPI module is based on the RAK439 module design of an Arduino-compatible development board, which inherited the RAK439 the SPI interface, supporting STM32F4, STM32F1 chip can be the fastest to 8Mb / s throughput speed, used for large data communications Suitable, of course, RAK439 low-power mode will allow the module does not need to transmit data, reduce the overall power consumption, saving electricity.

3.Quick to use

The sample code is the NOS code, mainly to test the module's sending speed, you can modify the module in the code set to AP mode or STA, you can choose to establish the type of SOCKET is TCP or UCP, Sever or Cliect. (Note that it is best to test the STA mode by connecting the module to a separate router, which may affect the real speed of the module)

Here the example code, for example, the module to do STA connection in a separate router, the module to establish TCP server, the computer set up TCP client connected, the test speed as shown below: (speed is variable, the maximum can reach 8Mb / S)
