• 【beacon operation instructions】

  ①Beacon can be used directly when it is powered on, long press the button in the middle above the beacon, flash three times to power on, and flash once to power off.
  *The booting method of some models is: turn the switch to ON to turn it on, and the upper light will flash three times.

  If you need to modify the parameters, please use the configuration software and follow the examples in the software tutorial. *Please contact customer service for software usage tutorials

  ③beacon parameter configuration software:
  [Apple] App store search: RL Beacon Tool software (software developed by our company)
  [Android] Use nordic official website software
  *Please confirm that all APP permissions are turned on, then turn on Bluetooth and location at the same time, and adjust the rssi value to a suitable position (about one third)
  *The default password of the software to connect the device is 123456, if there is an error, please contact customer service
  *The software needs to enter the password successfully within 15 seconds to connect the device, otherwise an error will occur and you need to reconnect

  
  ④【Nordic official website software】
  Download the compressed package of nrf software in the network disk link
  The nrf software tutorial introduces the steps to modify the name, and you can refer to this operation for modifying other parameters.
  *To modify the name, you need to input: 11+ corresponding ASCII code.
  *Modify the UUID and MAC address, just enter the corresponding value directly, without hex conversion.
  *Since MAJOR and MINOR are a continuous decimal value, they need to be converted to hexadecimal during the hexadecimal conversion. For example: major=10002, converted to 2712, minor=31, converted to 001F. Then you need to enter: 14+2712001FD8. D8 is the dbm of rssi at 1 meter, so there is no need to modify it by default.

  ⑤【Common Error】: No signal, unable to connect
  Please check several reasons first:
  1. Is the beacon powered on? Are the lights flickering? (The light is flashing and the boot is successful)
  2. Can the Bluetooth of the mobile phone detect the beacon? (If yes, the beacon is working properly)
  3. Adjust the rssi range of the software to a suitable position, and the mobile phone is close to the beacon, can it receive the signal? (The rssi signal reception range is reduced to filter nearby interference signals)
  *If the above steps cannot be resolved, please contact customer service
