Abstract

A device includes a connector configured to be coupled to a storage device. The device also includes a controller coupled to the connector and powered via the connector. The controller is configured to receive log data from the storage device while powered via the connector. The controller is also configured to transmit the log data via a wireless interface to a remote device.

Claims

1. A device comprising:

a connector configured to be coupled to a storage device; and

a controller coupled to the connector, the controller powered via the connector, the controller configured to receive log data from the storage device while powered via the connector and configured to transmit the log data via a wireless interface to a remote device.

2. The device of claim 1, wherein the controller is configured to transmit the log data via the wireless interface while powered via the connector.

3. The device of claim 1, wherein the connector comprises a universal asynchronous receiver/transmitter (UART) connector, a joint test action group (JTAG) connector, or a universal serial bus (USB) connector.

4. The device of claim 1, further comprising a memory configured to store the log data.

5. The device of claim 4, wherein the memory comprises a secure digital (SD) memory.

6. The device of claim 1, further comprising a wireless interface coupled to the controller and configured to transmit the data to the remote device.

7. The device of claim 1, wherein the wireless interface comprises a Bluetooth interface, a Zigbee interface, or a near field communication (NFC) interface.

8. The device of claim 1, further comprising:

a data logger device including the connector, the controller, and the wireless interface; and

the storage device coupled to the data logger device, the storage device comprising;

a second connector configured to be coupled to the connector of the data logger device;

an interface configured to be coupled to an access device;

a non-volatile memory configured to store data received from the access device via the interface; and

a memory controller coupled to the non-volatile memory, the memory controller configured to generate the log data, wherein the log data comprises an error log associated with the storage device.

9. The device of claim 8, wherein the storage device comprises a solid state drive, and wherein the data logger device is embedded within the storage device.

10. A device comprising:

a connector configured to be coupled to a storage device;

a wireless interface configured to receive control data from a remote device, the control data indicating one of multiple modes of operation; and

a controller coupled to the connector and to the wireless interface, the controller configured to set a mode of operation according to the control data, the mode of operation associated with reception of log data from the storage device via the connector, transmission of the log data to the remote device via the wireless interface, or both.

11. The device of claim 10, further comprising a battery coupled to the controller.

12. The device of claim 10, further comprising a memory configured to store the log data, wherein, if the mode of operation is a first mode, the controller is configured to receive the log data from the storage device and to store the log data in the memory.

13. The device of claim 12, wherein, if the mode of operation is a second mode, the controller is configured to access the log data from the memory and to transmit the log data to the remote device.

14. The device of claim 10, further comprising a memory configured to store the log data, wherein, if the mode of operation is a third mode, the controller is configured to receive the log data from the storage device, to store the log data in the memory, and to initiate transmission of the log data to the remote device.

15. A method comprising:

receiving, via a connector of a data logger device, log data from a storage device while the data logger device is powered by the storage device; and

transmitting the log data via a wireless interface of the data logger device to a remote device.

16. The method of claim 15, further comprising:

prior to transmitting the log data, storing the log data in a memory of the data logger device; and

receiving a request for the log data from the remote device, wherein the log data is transmitted to the remote device responsive to the request.

17. The method of claim 15, further comprising:

receiving a request from the remote device for authentication; and

authenticating the remote device to enable secure peer-to-peer wireless communication between the remote device and the data logger device.

18. The method of claim 15, further comprising:

receiving control data from the remote device, wherein the control data indicates one of multiple operating modes of the data logger device; and

configuring the data logger device to operate based on an operating mode indicated by the control data.

19. The method of claim 18, further comprising, if the operating mode is a first mode, storing the log data in a memory of the data logger device without transmitting the log data from the data logger device to the remote device.

20. The method of claim 19, further comprising, if the operating mode is a second mode:

accessing the log data from the memory; and

initiating transmission of the log data from the data logger device to the remote device.

21. The method of claim 19, further comprising, in response to receiving power from the storage device via the connector:

powering on the controller; and

setting the operating mode to a default mode.

22. The method of claim 21, wherein the default mode comprises the first mode.

23. The method of claim 18, further comprising, if the operating mode is a third mode:

storing the log data in a memory of the data logger device; and

initiating transmission of the log data from the data logger device to the remote device.
