Multi Device Broadcast Network For Context And Awareness

A radio controller for a device, comprising:

• a radio controller configured to:
• receive a first scan interval from a primary host of the device and a second scan interval from a secondary host of the device;
• schedule primary host scan windows based on the first scan interval from the primary host;
• determine any secondary host scan windows overlapping any of the scheduled primary host first scan windows based at least in part on the second scan interval from the secondary host;
• and
• cancel any secondary host second scan windows determined to overlap any of the scheduled primary host first scan windows.

A method for supporting context broadcast networking by a device, comprising:

• determining, on a low power island of the device interfacing with a radio controller of the device, whether a broadcast message received from the radio controller indicates an account identity value matching a pre-calculated account identity value;
• determining, on the low power island of the device, whether the broadcast message received from the radio controller is a duplicate message in response to determining that the broadcast message received from the radio controller indicates an account identity value matching a pre-calculated account identity value;
• decrypting, on the low power island of the device, at least a portion of the broadcast message received from the radio controller in response to determining that the broadcast message received from the radio controller is not a duplicate message;
• generating, on the low power island of the device, one or more data elements from the broadcast message received from the radio controller in response to decrypting the at least a portion of the broadcast message received the radio controller;
• sending the one or more data elements from the lower power island of the device to a shared data cache of the device;
• and
• signaling or sending, from the low power island of the device to another processor of the device, an interrupt indicating the one or more data elements are available in the shared data cache.

A method for radio controller periodic scan scheduling for a device, comprising:

• receiving at a radio controller of the device a first scan interval from a primary host of the device and a second scan interval from a secondary host of the device;
• scheduling, by the radio controller, primary host scan windows based on the first scan interval from the primary host;
• determining, by the radio controller, any secondary host scan windows overlapping any of the scheduled primary host first scan windows based at least in part on the second scan interval from the secondary host;
• and
• cancelling any secondary host second scan windows determined to overlap any of the scheduled primary host first scan windows.
