Abstract

The invention discloses a method and device compatible with wireless charging and NFC. The method includes: setting an antenna dedicated to receiving wireless charging signals and near-field communication NFC signals on a communication terminal; Whether the antenna is currently receiving a wireless charging signal or an NFC signal is judged; if it is determined that the current receiving is a wireless charging signal, the judging circuit module transmits the charging signal received by the antenna to the wireless charging receiving circuit module of the communication terminal to receive wireless energy; If it is determined that the current received signal is an NFC signal, the determination circuit module enables the NFC module of the communication terminal to communicate via the antenna. The present invention can effectively realize the coexistence and compatibility of wireless charging and NFC, and can solve the problem that wireless charging and NFC share the same coil.

Description

technical field [0001] The invention relates to the fields of wireless charging and NFC (Near Field Communication), in particular to a method and device compatible with wireless charging and NFC. Background technique [0002] At present, mobile terminals are used more and more widely, and the functions of the terminals are very powerful, full of rich entertainment, such as listening to music, watching TV, surfing the Internet and so on. In the process of using the mobile terminal, due to the limitation of the battery capacity, people find that the power of the battery is used up soon, and the battery often needs to be charged. The emergence of wireless charging technology represented by electromagnetic induction has brought convenience to consumers. The wireless charging device can conveniently charge the mobile phone, freeing consumers from the shackles of wires. [0003] Near field communication NFC, also known as short-range wireless communication, is a short-range wire...
