Monitoring system and method for a mobile device

A non-transitory storage medium storing a set of instructions, the set of instructions capable of being executed by a first mobile device to cause the first mobile device to perform a method for wirelessly monitoring a second mobile device, the method comprising:

• setting at least one prompting file for prompting a user of the first mobile device, a time interval for monitoring the second mobile device, and a name of a second communication module of the second mobile device;
• enabling a first communication module of the first mobile device, and controlling the first communication module to search for one or more discoverable devices within a predetermined coverage area of the first mobile device;
• entering a name of each found discoverable device in a device list of the first mobile device;
• determining whether the second communication module is found according to the presence or absence of the name of the second communication module in the device list;
• starting timing the time interval, if the second communication module is found;
• controlling the first communication module to search for the discoverable devices within the predetermined coverage area after the time interval has elapsed, in order to update the device list;
• determining whether the second communication module is in the updated device list;
• and
• outputting the at least one prompting file using an output device of the first mobile device for prompting the user that the second mobile device has moved too far away from the first mobile device, if the second communication module is found to be absent from the updated device list.

A mobile device, comprising:

• a first communication module;
• a storage system;
• at least one processor;
• an output device;
• and
• one or more programs that are stored in the storage system and executed by the at least one processor, the one or more programs comprising:
• a setting module that sets at least one prompting file for prompting a user of the mobile device, a time interval for monitoring a second mobile device, and a name of a second communication module of the second mobile device;
• a starting module that enables the first communication module;
• a control module that controls the first communication module to search for one or more wirelessly discoverable devices within a predetermined coverage area of the mobile device, and enters a name of each found discoverable device in a device list of the mobile device;
• a first determination module that determines whether the second communication module is found according to the presence or absence of the name of the second communication module in the device list;
• a timer that starts timing the time interval;
• a second determination module;
• and
• an output module;
• wherein the control module also controls the first communication module to search for the discoverable devices within the predetermined coverage area in order to update the device list, when the time interval has elapsed;
• the second determination module determines whether the second communication module is in the updated device list;
• and
• the output module outputs the at least one prompting file using the output device for prompting the user that the second mobile device has moved too far away from the mobile device, if the second communication module is found to be absent from the updated device list.
