Now many people have bought a new pair of Bluetooth headsets because they lost one. Lentz Technology has put forward an anti-loss scheme for Bluetooth headsets, so that everyone can find the lost Bluetooth headsets themselves and avoid the loss of Bluetooth headsets.
Principle of anti-loss function of Bluetooth headset;
The wireless communication between mobile phone and Bluetooth headset is based on Bluetooth 5.2 protocol, which is basically based on the signal strength (RSSI) during communication, plus some filtering algorithms to measure the distance between mobile phone and Bluetooth headset. On the basis of RSSI ranging, after the loss alarm condition set by the user, the loss alarm function with Bluetooth headset is realized and collected. Through the buttons on the mobile phone or Bluetooth headset, you can control the sound of the other party sending books and realize the function of finding food.
Anti-lost search:
The relative distance between the mobile phone and the Bluetooth headset is beyond the warning range, and an alarm will be given immediately. At the same time, you can find Bluetooth headsets through your mobile phone.
Powerful and stable performance:
It has the functions of adjustable distance (0-50 meters), anti-lost, searching, alarm (or incidental vibration), automatic power saving, etc. It adopts advanced AES 128 coding technology and has reliable and stable performance.
Lentz technology bluetooth BLE5.2 anti-loss equipment scheme
Lentz technology adopts Bluetooth BLE5.2 technology, which has the advantages of low power consumption, two-way anti-loss and automatic alarm. But there are many kinds of products on the market, but its core components generally include: Bluetooth 5.2 chip, Bluetooth chip auxiliary circuit, Bluetooth antenna, buzzer, switch, power supply and so on.
Function description: Ble5.2 ultra-low power chip, TSSOP 16, FLASH 256K, internal space of 64K, supporting external EEPROM consumer chip.
Lentz Technology independently develops wireless RF and low-power Bluetooth BLE5.2 chips, which have global intellectual property rights. For the AIoT field and individual consumers, Lentz Technology provides "software and hardware * * * *" solutions and Bluetooth master fully integrated chip core devices to support customized development of all-round APP software platforms. The Bluetooth chip scheme is suitable for smart wearable devices, Bluetooth indoor navigation, smart home, medical health, physical exercise, data transmission, remote control, personal peripherals and AIoT.
The latest Bluetooth chip ST 17H66(SOP 16) with high performance and low power consumption 32-bit processor supports Bluetooth 5.2, and has Bluetooth LE and SIG MESH functions.
