Wireless broadcast and detection of data availability

A mobile device for connecting temporarily to wireless devices indicating availability of updated data, comprising:

• at least one wireless transceiver;
• and
• at least one processor coupled to the at least one wireless transceiver, the at least one processor is adapted to execute code, the code comprising:
• code instructions to receive a device identifier of at least one wireless device broadcasted by the at least one wireless device via at least one wireless channel and intercepted by at least one wireless transceiver of the mobile device, the identifier comprising a fixed part uniquely identifying the at least one wireless device and an adjustable part indicative of data available at the at least one wireless device;
• code instructions to compare between the adjustable part of the intercepted device identifier and the adjustable part of a previously intercepted device identifier of the at least one wireless device identified by the fixed part;
• code instructions to establish a connection with the at least one wireless device via the at least one wireless channel in case the adjustable part of the intercepted device identifier is different from the adjustable part of the previously intercepted device identifier;
• code instructions to communicate with the at least one wireless device to receive updated data associated with the adjustable part of the intercepted device identifier;
• and
• code instructions to terminate the connection with the at least one wireless device.

A method of indicating availability of updated data by a wireless channel, comprising:

• using at least one processor of a wireless device for:
• collecting updated data;
• adjusting a device identifier of the wireless device, the device identifier comprising a fixed part uniquely identifying the wireless device and an adjustable part indicative of the updated data;
• broadcasting the adjusted fixed device identifier via at least one wireless channel;
• wherein, in response to interception of the adjusted device identifier, at least one mobile device establishes a connection with the wireless device via the at least one wireless channel to receive the updated data and terminates the connection after receiving the updated data.

A wireless device, comprising:

• at least one wireless transceiver configured to connect to at least one wireless channel;
• and
• at least one processor coupled to the at least one wireless transceiver, the at least one processor is adapted to execute code, the code comprising:
• code instructions to collect updated data;
• code instructions to adjust a device identifier of the wireless device, the device identifier comprising a fixed part uniquely identifying the wireless device and an adjustable part indicative of the updated data;
• and
• code instructions to broadcast the adjusted device identifier via at least one wireless channel;
• wherein, in response to interception of the adjusted device identifier, at least one mobile device establishes a connection with the wireless device via the at least one wireless channel to receive the updated data and terminates the connection after receiving the updated data.
