Abstract
A method of establishing a low latency connection between a first device and a second device on a wireless network is presented. The method contains the steps of: forming a first wireless connection between the first and second devices; forming at least a second and parallel wireless connection between the first and second devices; and sending data between the first and second devices using at least the first and second connections. For any wireless protocol for data exchange between devices that specifies a minimum interval between data exchange events, the present disclosure enables a lower latency than would otherwise be achievable according to a standard protocol.
Claims12
A method of establishing a low latency wireless connection between a master device and a slave device, the method comprising the steps of:
- forming a first wireless connection between the master and slave devices according to a BLE network protocol;
- after forming of the first wireless connection, adopting a different MAC address for the slave device;
- after adopting the different MAC address, forming at least a second and parallel wireless connection between the master and slave devices according to said BLE network protocol;
- and
- sending data from the slave device to the master devices using at least the first and second connections.
A system of wirelessly connected devices, the system comprising:
- a master device and a slave device;
- wherein the system is configured to provide a first wireless connection between the master and slave devices according to a BLE network protocol and then to provide at least a second and parallel wireless connection between the master and slave devices according to said same BLE network protocol,
- wherein the slave device adopts a different MAC address for each of said first and second wireless connections;
- and wherein data is sendable between the master and slave devices using at least the first and second wireless connections.
A master device which is wirelessly connectable to a slave device, the master device comprising:
- a radio transceiver which is configured to provide a first wireless connection between the master device and slave device according to a BLE network protocol,
- wherein the radio transceiver is configured to provide a second and parallel wireless connection between the master device and the slave device according to said BLE network protocol,
- wherein the slave device adopts a different MAC address for said each of said first and second wireless connections;
- and
- wherein data is sendable between the master device and the slave device using at least the first and second wireless connections.
A slave device which is wirelessly connectable to a master device, the slave device comprising:
- a radio transceiver which is configured to provide a first wireless connection between the master device and slave device according to a BLE network protocol,
- wherein the radio transceiver is configured to provide a second and parallel wireless connection between the master device and the slave device according to said same BLE network protocol,
- the slave device is configured to specify a second MAC address prior to forming the second wireless connection;
- and
- wherein data is sendable between the master device and the slave device using at least the first and second wireless connections.
