Central priority advertisement for medical devices
Techniques are disclosed for enabling a first central device to connect with a medical device with an existing connection to a second central device by broadcasting a “central priority” advertisement packet that causes the second central device to discontinue attempts to connect with the medical device (for a period of time), granting the first central device the ability to establish communication with the medical device.

wirelessly receive, during the period of time, a second advertisement packet via the wireless communication interface, the second advertisement packet sent from a medical device; and
in response to receiving the second advertisement packet, establish a wireless communication session via the wireless communication interface between the central device and the medical device.
9. The central device of claim 8 , wherein the central device is further configured to receive, prior to receiving the second advertisement packet, an acknowledgment from the other central device via the wireless communication interface that the other central device received the first advertisement packet.
10. The central device of claim 8 , wherein the processing unit is further configured to cause the central device to include, in the first advertisement packet, information indicating a length of the period of time.
11. The central device of claim 8 , wherein the processing unit is further configured to cause the central device to include, in the first advertising packet, an identifier of the medical device.
12. The central device of claim 11 , further comprising a camera, wherein the processing unit is further configured to cause the central device to obtain the identifier of the medical device using the camera.
13. The central device of claim 8 , wherein the processing unit is configured to determine the triggering event has occurred by being further configured to determine a user input has been received by the central device.
14. The central device of claim 8 , wherein the processing unit is configured to determine the triggering event has occurred by being further configured to determine a location of the central device is within a particular locale.
15. An apparatus for operating as a first central device, the apparatus comprising:
means for determining a triggering event has occurred, wherein the triggering event is a user-initiated action at a medical device;
means for wirelessly broadcasting a first advertisement packet in response to determining the triggering event has occurred, wherein the first advertisement packet is configured to cause a second central device to enter a hold off state for a period of time;
means for wirelessly receiving, during the period of time, a second advertisement packet, the second advertisement packet sent from the medical device; and
means for establishing a wireless communication session between the first central device and the medical device in response to receiving the second advertisement packet.
16. The apparatus of claim 15 , further comprising means for receiving, prior to receiving the second advertisement packet, an acknowledgment from the second central device that the second central device received the first advertisement packet.
17. The apparatus of claim 15 , further comprising means for including, in the first advertisement packet, information indicating a length of the period of time.
18. The apparatus of claim 15 , further comprising means for including, in the first advertisement packet, an identifier of the medical device.
19. The apparatus of claim 18 , further comprising image-capturing means configured to obtain the identifier of the medical device.
20. The apparatus of claim 15 , wherein the means for determining the triggering event has occurred comprises means for determining a user input has been received by the first central device.
21. The apparatus of claim 15 , wherein the means for determining the triggering event has occurred comprises means for determining a location of the first central device is within a particular locale.
22. An non-transitory computer-readable medium having instructions embedded thereon, the instructions including computer code for:
determining, with a first central device, a triggering event has occurred, wherein the triggering event is a user-initiated action at a medical device;
wirelessly broadcasting a first advertisement packet in response to determining the triggering event has occurred, wherein the first advertisement packet is configured to cause a second central device to enter a hold off state for a period of time;
wirelessly receiving, during the period of time, a second advertisement packet, the second advertisement packet sent from the medical device; and
establishing a wireless communication session between the first central device and the medical device in response to receiving the second advertisement packet.
23. The non-transitory computer-readable medium of claim 22 , further comprising computer code for receiving, prior to receiving the second advertisement packet, an acknowledgment from the second central device that the second central device received the first advertisement packet.
24. The non-transitory computer-readable medium of claim 22 , further comprising computer code for including, in the first advertisement packet, information indicating a length of the period of time.
25. The non-transitory computer-readable medium of claim 22 , further comprising computer code for including, in the first advertisement packet, an identifier of the medical device.
26. The non-transitory computer-readable medium of claim 25 , further comprising computer code for obtaining the identifier of the medical device using a camera of the first central device.
27. The non-transitory computer-readable medium of claim 22 , wherein the computer code for determining the triggering event has occurred comprises computer code for determining a user input has been received by the first central device.
28. The non-transitory computer-readable medium of claim 22 , wherein the computer code for determining the triggering event has occurred comprises computer code for determining a location of the first central device is within a particular locale.
