1.Configure Anchor0

• Open the get_range.ino by Arduino IDE. This program parses the AT instructions into JSON format and uploads them through the serial port.
• Use Type-C USB cable to connect the board and PC, and select the development board "ESP32 Dev Module" and the port.
• Verify the code and upload.

2.Configure other devices

• Open the esp32_at_t0.ino by Arduino IDE.
• Use Type-C USB cable to connect the board and PC, and select the development board "ESP32 Dev Module" and the port.
• Change module settings

  #define UWB_INDEX 0  //Device ID(Anchor 0-7，Tag 0-31)
  
  #define TAG
  // #define ANCHOR    //Device Role(Tag or Anchor)
  
  #define FREQ_850K
  // #define FREQ_6800K    //Equipment communication rate(850K or 6800k)

• Verify the code and upload.

Note configure at least three Anchors for positioning.
