To achieve quick pairing and connection of the Bluetooth lock using BLE HID attributes when the phone is within a certain range, it is necessary to combine the following key technical modules to create a “proximity automatic unlocking experience“. Objective Description •The lock is a BLE HID device (simulating input unlock commands) •When the phone … Read more
In smart padlocks, the design of switching between BLE HID + GATT + OTA/DFU protocols is a common multi-protocol multiplexing solution suitable for low-power smart devices, requiring flexible switching between HID input, standard BLE service communication (such as GATT), and OTA firmware upgrades. Design Objective:A three-state working mechanism of BLE HID + GATT + DFU, … Read more
In the design of BLE HID (Bluetooth Low Energy Human Interface Device) devices, power consumption is a critical technical indicator, especially for battery-powered devices such as wireless keyboards, mice, remote controls, headphone controllers, and game controllers. A good BLE HID design typically requires long standby time, quick wake-up, efficient transmission, and extremely low power consumption. … Read more
Although BLE HID (Bluetooth Low Energy Human Interface Device) has a simple structure and low power consumption during development, it often encounters tricky issues due to challenges in cross-platform compatibility, security certification, and connection stability. Below are common problems and corresponding solutions applicable to scenarios involving the development of BLE HID keyboards, mice, remote controls, … Read more
