As the country vigorously advocates and develops the new energy automobile industry, innovative technologies for the Internet of Vehicle are gradually being used in automobiles. More and more people have also put forward the demand for convenient travel, hoping that the car can be unlocked and started with a mobile phone.

Passive Entry Passive Start (PEPS) is a secure wireless communication system that enables a driver to access their car (unlocking the car and starting the engine) without physically using a key. This system uses RF signals for authenticating the key by sending signals between the car and key. PEPS has more intelligent access control management, higher anti-theft performance, and has become the mainstream of automotive electronic anti-theft system applications.

As the country vigorously advocates and develops the new energy automobile industry, innovative technologies for the Internet of Vehicle are gradually being used in automobiles. More and more people have also put forward the demand for convenient travel, hoping that the car can be unlocked and started with a mobile phone.

Therefore, Feasycom has launched a Bluetooth solution based on TI's automotive grade Bluetooth chip CC2640R2F, and cooperates with service providers that provide automobile manufacturers with automotive electronic systems. Through cross-technology integration, realizes a new Bluetooth PEPS solution: use the digital key to enter and start the car. Use the mobile phone APP to receive the Bluetooth broadcast signal, then judge the distance between the phone and the car, thereby executing functions such as unlocking or locking the car and starting the engine.
