A method and system are described for proximity detection performed at an electronic device. In the described embodiments, an application is executing on the electronic device. The electronic device determines a target wireless signal strength based on a target distance. The electronic device receives a Bluetooth low energy (BLE) wireless signal from a second electronic device and generates a received wireless signal strength based on the received BLE wireless signal. The electronic device then compares the received wireless signal strength to the target wireless signal strength and on the condition that the received wireless signal strength exceed the target wireless signal strength, the electronic device performs one or more operations wherein the one or more operations include restricting a functionality of the application. |
