Charge-based peripheral device selection

1. A primary wireless communication device, comprising:

an output assembly;

a short-range communications assembly;

a pairing controller configured to:

send a discovery request for detection by a plurality of secondary wireless communication devices;

responsive to sending the discovery request, receive a plurality of discovery responses from respective secondary wireless communication devices, each discovery response containing a respective identifier of the corresponding secondary wireless communication device and respective charge data for the corresponding secondary wireless communication device;

compare the charge data from each of the discovery responses to a lower threshold and to an upper threshold greater than the lower threshold;

select a subset of the secondary wireless communication devices having charge data above the lower threshold;

control the output assembly to (i) present a list of respective identifiers and respective charge data of the secondary wireless communication devices in the subset, excluding the secondary wireless communication devices not in the subset, and (ii) indicate, in the list, the charge data that falls below the upper threshold;

obtain an instruction to establish a paired communication link with one of the secondary wireless communication devices selected from the list; and

responsive to obtaining the instruction, initiate a pairing stage to establish the paired communication link.

2. The primary wireless communication device of claim 1 , wherein the paired communication link is based on a Bluetooth standard;

wherein each of the discovery responses is an Extended Inquiry Response (EIR) message; and

wherein the respective charge data is contained within a manufacturer data field of the EIR.

3. The primary wireless communication device of claim 1 , further comprising an input assembly; wherein the controller is configured, in order to obtain the instruction, to receive a selection of the one of the secondary wireless communication devices from the list via the input assembly.

4. The primary wireless communication device of claim 1 , wherein the respective charge data includes a battery level.

5. A method, comprising:

sending a discovery request from a primary wireless communication device, for detection by a plurality of secondary wireless communication devices;

responsive to sending the discovery request, receiving a plurality of respective discovery responses at the primary wireless communication device from respective secondary wireless communication devices, each discovery response containing a respective identifier of the corresponding secondary wireless communication device and respective charge data for the corresponding secondary wireless communication device;

comparing the charge data from each of the discovery responses to a lower threshold and to an upper threshold greater than the lower threshold;

selecting a subset of the secondary wireless communication devices having charge data above the lower threshold;

controlling an output assembly of the primary wireless communication device to (i) present a list of respective identifiers and respective charge data of the secondary wireless communication devices in the subset, excluding the secondary wireless communication devices not in the subset, and (ii) indicate, in the list, the charge data that falls below the upper threshold;

obtaining an instruction to establish a paired communication link with one of the secondary wireless communication devices selected from the list; and

responsive to obtaining the instruction, initiating a pairing stage to establish the paired communication link.

6. The method of claim 5 , wherein the paired communication link is based on the Bluetooth standard, and wherein each of the plurality of discovery responses is an Extended Inquiry Response (EIR) message.

7. The method of claim 5 , wherein obtaining the instruction includes receiving a selection of the one of the secondary wireless communication devices from the list via an input assembly of the primary wireless communication device.

8. The method of claim 5 , wherein the charge data includes a battery level.
