BLE Smart Home Solution

Home appliance upgrades,
make your home smarter!

With the continuous advancement and popularization of IoT technology, smart home appliances are empowered by technology, combining traditional home appliances with microcontrollers, wireless communications, sensors and other technologies, allowing users to communicate through the Internet or other communication technologies, such as BLE and Zigbee. Realize functions such as device status acquisition, remote device control, and intelligent adjustment.

As a short-range wireless communication technology, BLE technology is widely used in mobile devices. Its biggest advantage is that it can communicate without any network or infrastructure, which makes it ideal for connecting personal mobile devices such as mobile phones, tablets and smart home appliances. Bluetooth communication technology also has high security. After the connection is established, the communication devices will verify each other's identities and security keys to ensure the security of the communication process.

Feature Highlights

Reliability and Stability

Smart home appliance systems must be stable and reliable during use to provide a good user experience. This requires ensuring that BLE devices, as wireless communication links, have stable and reliable connections in complex electromagnetic environments.

Multiple Connection Support

During the use of smart home appliances, there are often multiple operating users. For example, multiple family members can control a smart fan from a mobile device. This requires BLE devices to support multiple connections at the same time.

Master-slave Integrated Support

Some smart home appliances also need to be linked with other devices. For example, a smart air conditioning system can obtain information such as ambient temperature and humidity by connecting to sensor nodes. At the same time, mobile devices such as mobile phones need to be connected to the air conditioner to control it.

Safety

Smart home appliance systems need to have good security to protect devices from hackers or malicious network applications.

Solution Technical Specifications

It uses a 32-bit ARM Cortex®-M0 core with a maximum operating frequency of 64MHz. There are 256KB Flash and 48KB SRAM integrated on the chip. Integrated advanced BLE5.1 radio frequency transceiver, compliant with BLE5.1 specification, can be configured as standard 1Mbps BLE mode, 2Mbps enhanced BLE mode, 125kbps BLE long range mode (S8), 500kbps BLE long range mode (S2). Supports Bluetooth mesh, supports AOA (angle of arrival) and AOD (angle of departure), and supports RSSI (receiver signal strength indication). Can support master-slave mode at the same time, support multiple connections, and support data packet length expansion. It integrates a wealth of peripheral units, supports KEYSCAN, IRC, 10-bit 1.33Msps ADC (configurable to 16-bit 16Ksps), supports basic, general, advanced TIMER, RTC, WWDG, LPUART, USART, SPI, I2C and other peripherals.

User Binding

When using it for the first time, car owners need to perform device binding operations through the App on their mobile phones.

BLE Automatic Connection

When the owner approaches the vehicle, the keyless entry system automatically connects with the owner's smartphone via Bluetooth. Only authorized user mobile phones can establish a normal connection.

Authentication

Once the Bluetooth connection is established, the keyless entry system will further verify identity.

Distance Calculation

The keyless entry system calculates the distance between the vehicle and the user by judging the signal strength.

Automatically Unlock

Once the user's identity is successfully authenticated and the user is within unlocking range, the system will unlock the vehicle's handlebar lock or electronic lock. Owners can easily push the vehicle or start the motor using the starter button.

Automatic Lock

When the user moves away from the vehicle, the keyless entry system will automatically perform a locking operation.
