Abstract

Aspects of the present disclosure are related to provisioning of wireless devices. In an embodiment, a wireless device (sought to be provisioned) receives values for provisioning parameters from an external user device, and attempts to join a wireless local network according to the received values for the provisioning parameters. The wireless device sends a response to the external user device indicating whether or not the joining was successful. The external user device may display the result indicating whether or not provisioning was successful. The wireless device may operate in a time division multiplexed manner as an access point (for securing the credentials) and as a station (once provisioning is complete).

First claim

What is claimed is:

1. A method of provisioning a wireless device, said method being performed in said wireless device, said method comprising:
receiving values for provisioning parameters from an external user device;
attempting to join a wireless local network according to the received values for the provisioning parameters;
sending a response that includes a positive acknowledgment to said external user device that indicates whether or not said joining was successful;
operating as an access point for said receiving such that said external user device operates as a wireless station to transmit said values for said provisioning parameters;
operating as a wireless station for said attempting;
sending an additional packet to an access point (AP) after completion of said joining; and
determining that said joining is successful only if a response is received to said additional packet, and determining that said joining is unsuccessful otherwise,
wherein said wireless device operates in time division multiplexed (TDM) mode such that said wireless device operates as said access point in a first set of durations and as said wireless station in said second set of durations, wherein none of said first set of durations overlaps with any of said second set of durations, whereby said values are received from said external user device and said response is sent in said first set of durations and said attempting is performed in said second set of durations, and
wherein said wireless device operates exclusively as said wireless station after sending said response if said joining was successful.

2. The method of claim 1 , wherein said additional packet is sent and corresponding response to said additional packet is received in said second set of durations.

3. The method of claim 2 , wherein said provisioning parameters comprise a service set identifier (SSID) of said wireless local network and security credentials required to join said wireless local network, wherein said attempting to join comprises transmitting packets for association with said wireless local network and authentication based on values received for a set of authentication parameters.

4. The method of claim 1 , further comprising:
sending data to said external user device indicating whether or not said wireless device has the ability to operate in said TDM mode; and
wherein said response is sent to said external device only if said sent data indicates that said wireless device has the ability to operate in said TDM mode.

5. A non-transitory machine readable medium storing one or more sequences of instructions in a wireless device, wherein execution of said one or more instructions by one or more processors contained in said wireless device enables said wireless device to perform the actions of:
receiving values for provisioning parameters from an external user device;
attempting to join a wireless local network according to the received values for the provisioning parameters;
sending a response that includes a positive acknowledgment to said external user device that indicates whether or not said joining was successful;
operating as an access point for said receiving such that said external user device operates as a wireless station to transmit said values for said provisioning parameters;
operating as a wireless station for said attempting;
sending an additional packet to an access point (AP) after completion of said joining; and
determining that said joining is successful only if a response is received to said additional packet, and determining that said joining is unsuccessful otherwise,
wherein said wireless device operates in time division multiplexed (TDM) mode such that said wireless device operates as said access point in a first set of durations and as said wireless station in said second set of durations, wherein none of said first set of durations overlaps with any of said second set of durations, whereby said values are received from said external user device and said response is sent in said first set of durations and said attempting is performed in said second set of durations, and
wherein said wireless device operates exclusively as said wireless station after sending said response if said joining was successful.

6. The non-transitory machine readable medium of claim 5 , wherein said provisioning parameters comprise a service set identifier (SSID) of said wireless local network and security credentials required to join said wireless local network, wherein said attempting to join comprises transmitting packets for association with said wireless local network and authentication based on values received for a set of authentication parameters.

7. A wireless device comprising: a processing block and a memory, said memory to store instructions which when retrieved and executed by said processing block cause said wireless device to perform the actions of:
receiving values for provisioning parameters from an external user device;
attempting to join a wireless local network according to the received values for the provisioning parameters;
sending a response that includes a positive acknowledgment to said external user device that indicates whether or not said joining was successful;
operating as an access point for said receiving such that said external user device operates as a wireless station to transmit said values for said provisioning parameters;
operating as a wireless station for said attempting;
sending an additional packet to an access point (AP) after completion of said joining; and
determining that said joining is successful only if a response is received to said additional packet, and determining that said joining is unsuccessful otherwise,
wherein said wireless device operates in time division multiplexed (TDM) mode such that said wireless device operates as said access point in a first set of durations and as said wireless station in said second set of durations, wherein none of said first set of durations overlaps with any of said second set of durations, whereby said values are received from said external user device and said response is sent in said first set of durations and said attempting is performed in said second set of durations, and
wherein said wireless device operates exclusively as said wireless station after sending said response if said joining was successful.

8. The wireless device of claim 7 , wherein said memory further comprises instructions to enable said wireless device to perform the actions of: sending data to said external user device indicating whether or not said wireless device has the ability to operate in said TDM mode; and wherein said response is sent to said external device only if said sent data indicates that said wireless device has the ability to operate in said TDM mode.
