Abstract

Example implementations relate to beacon sensor device state transition. In some examples, a beacon sensor device can include a communication resource and a processing resource. In some examples, the beacon sensor device can include a memory resource storing machine readable instructions to cause the processing resource to perform at particular, non-uniform time intervals, a plurality of scans of a same duration of other beacon sensor devices within a same network as the beacon sensor device for a state transition notification. In response to the communication resource detecting the state transition notification, the beacon sensor device can be transitioned to a state corresponding to the state transition notification in some examples.

Claims

1. A Bluetooth low energy (BLE) device comprising:

a communication resource;

a processing resource;

a memory resource storing machine readable instructions to cause the processing resource to;

perform at particular, non-uniform time intervals, a plurality of scans of a same duration of other BLE devices within a same network as the BLE device for a state transition notification, wherein the particular non-uniform time intervals comprise at least two or more of one minute, two minutes, four minutes, and eight minutes, wherein the first duration of time is 133 milliseconds and the second duration of time is 200 milliseconds; and

in response to the communication resource detecting the state transition notification, transition the BLE device to a state corresponding to the state transition notification.

2. The BLE device of claim 1, further comprising the memory resource to cause the processing resource to perform the plurality of scans for a dormant-to-active state transition notification.

3. The BLE device of claim 1, further comprising the memory resource to cause the processing resource to perform the plurality of scans for an active-to-dormant state transition notification.

4. The BLE device of claim 1, wherein the same duration is 150 milliseconds.

5. A Bluetooth low energy (BLE) device comprising:

a communication resource;

a processing resource; and

a memory resource storing machine readable instructions to cause the processing resource to iteratively;

perform for a duration, a first scan of a neighboring BLE device for a state transition notification;

perform, subsequent to the first scan, a plurality of scans of the neighboring BLE device for the state transition notification until a sum of scan intervals reaches a threshold, wherein each of the plurality of scans is performed for a particular duration at non-uniform time intervals that comprise at least two or more of one minute, two minutes, four minutes, and eight minutes, wherein a first duration of time is 133 milliseconds and a second duration of time is 200 milliseconds; and

in response to the communication resource detecting the state transition notification during the first scan or one of the plurality of scans, transition the BLE device to a state corresponding to the state transition notification.

6. The BLE device of claim 5, wherein the threshold scan interval sum is fifteen minutes.

7. The BLE device of claim 5, further comprising the memory resource to cause the processing resource to perform, subsequent to the first scan, a plurality of scans of the neighboring BLE device for the state transition notification until a cumulative scan duration reaches a threshold.

8. A non-transitory machine readable storage medium having stored thereon machine readable instructions to cause a computer processor to:

scan for a particular state transition notification, by a first plurality of Bluetooth low energy (BLE) devices, a network of BLE devices at a first time interval for a first duration of time;

scan for the particular state transition notification, by a second plurality of BLE devices, the network at a second time interval for the first duration of time;
