Connection and service discovery for fine ranging applications
Various systems and methods for providing discovering smart card slots in a device are described herein. A server device for discovering smart card slots in a client device may be implemented with a processor subsystem; and memory including instructions, which when executed by the processor subsystem, cause the processor subsystem to perform operations comprising: receiving, at the server device from the client device, over an established Bluetooth connection, smart card connector parameters, the client device having a plurality of smart card slots; iterating through the plurality of smart card slots; at each slot of the plurality of smart card slots, using a smart card protocol to attempt to access an application at each slot, the application pre-associated with the server device; and in response to identifying the application exists in a slot of the plurality of smart card slots, connecting with the application.
1. A server device for discovering smart card slots in a client device, comprising:
a processor subsystem; and
memory including instructions, which when executed by the processor subsystem, cause the processor subsystem to perform operations comprising:
receiving, at the server device from the client device, over an established Bluetooth connection, smart card connector parameters, the client device having a plurality of smart card slots;
using the smart card connector parameters, iterating through the plurality of smart card slots, over the Bluetooth connection, by interrogating each slot of the plurality of smart card slots using a smart card protocol to attempt to access an application at each slot, the application pre-associated with the server device; and
in response to identifying the application exists in a slot of the plurality of smart card slots, connecting with the application.
2. The server device of claim 1 , wherein the smart card connector parameters include at least one of a buffer size or a flag indicating whether the client device supports multiple open slots.
3. The server device of claim 1 , wherein iterating through the plurality of smart card slots includes:
identifying smart card types of each of the plurality of smart card slots;
filtering the plurality of smart card slots based on smart card types to produce filtered results; and
iterating through the filtered results.
4. The server device of claim 3 , wherein the smart card types include embedded Secure Element (eSE) and host card emulation (HCE).
5. The server device of claim 1 , wherein the plurality of smart card slots include a virtual smart card slot, a physical smart card slot, or a combination of a physical smart card slot and a virtual smart card slot.
6. The server device of claim 1 , wherein the smart card protocol includes ISO/IEC 7816.
7. The server device of claim 1 , wherein the application is pre-associated with the server device when the server device is initially provisioned for field service.
8. The server device of claim 7 , wherein the application implements ultra-wideband technology to provide ranging data to the server device.
9. The server device of claim 7 , wherein the operations comprise:
disconnecting from the Bluetooth connection with the application; and
establishing an ultra-wideband ranging session using data received from the application.
10. The server device of claim 1 , wherein the application is a fine ranging application.
11. A method for discovering smart card slots in a device, the method comprising:
receiving, at a server device from a client device, over an established Bluetooth connection, smart card connector parameters, the client device having a plurality of smart card slots;
using the smart card connector parameters, iterating through the plurality of smart card slots, over the Bluetooth connection, by interrogating each slot of the plurality of smart card slots using a smart card protocol to attempt to access an application at each slot, the application pre-associated with the server device; and
in response to identifying the application exists in a slot of the plurality of smart card slots, connecting with the application.
12. The method of claim 11 , wherein the smart card connector parameters include at least one of a buffer size or a flag indicating whether the client device supports multiple open slots.
13. The method of claim 11 , wherein iterating through the plurality of smart card slots includes:
identifying smart card types of each of the plurality of smart card slots;
filtering the plurality of smart card slots based on smart card types to produce filtered results; and
iterating through the filtered results.
14. The method of claim 13 , wherein the smart card types include embedded Secure Element (eSE) and host card emulation (HCE).
15. The method of claim 11 , wherein the plurality of smart card slots include a virtual smart card slot, a physical smart card slot, or a combination of a physical smart card slot and a virtual smart card slot.
16. The method of claim 15 , wherein the smart card protocol includes ISO/IEC 7816.
17. The method of claim 11 , wherein the application is pre-associated with the server device when the server device is initially provisioned for field service.
18. The method of claim 17 , wherein the application is a fine ranging application.
19. The method of claim 18 , wherein the application implements ultra-wideband technology to provide ranging data to the server device.
20. The method of claim 11 , comprising:
disconnecting from the Bluetooth connection with the application; and
establishing an ultra-wideband ranging session using data received from the application.
