Methods and apparatus for improved low energy data communications

A system comprising:

• a first device;
• and
• a second device,
• wherein the first device includes a controller having memory operative to store instructions executable on the controller, the instructions operative to:
• determine a reference value on the first device, wherein the reference value is not an actual or literal indication of status of the first device,
• broadcast the reference value from the first device,
• connect the first device to the second device if the second device requests data from the first device,
• transmit any new data if the second device requests data from the first device,
• generate and broadcast a new reference value if the first device has new data, wherein the new reference value is not an actual or literal indication of status of the first device, and
• broadcast the reference value from the first device again if the first device does not have new data;
• wherein the second device includes a controller having memory operative to store instructions executable on the controller, the instructions operative to:
• receive the reference value in the second device from the first device,
• wait for the new reference value if the received reference value matches a stored reference value,
• transmit a request from the second device for new data from the first device if the received reference value does not match the stored reference value,
• receive new data from the first device into the second device if the received reference value does not match the stored reference value, and
• store the received reference value as a new stored reference value if the received reference value does not match the stored reference value.

A wireless device comprising:

• a controller;
• and
• a memory coupled to the controller, the memory operative to store instructions executable on the controller and operative to:
• determine a reference value, wherein the reference value is not an actual or literal indication of status of the wireless device;
• broadcast the reference value;
• and
• connect to a smart device if the smart device requests new data from the wireless device after receiving the broadcast reference value and determining that the broadcast reference value does not match a stored reference value.
