Abstract

A method and device for transmitting data between a peripheral device and a user device via a Bluetooth Low Energy connection, comprising: at the peripheral device: transmitting data to the user device in a simulated data stream, the transmitting comprising: identifying a first Bluetooth characteristic for writing data, the first Bluetooth characteristic having been exposed by the peripheral device to the user device; dividing a data packet into a sequence of data frames plus zero or one remainder, each data frame having a respective size equal to a predetermined data size of the identified first Bluetooth characteristic; and for each of the sequence of data frames: writing the data frame to a respective value for the identified first Bluetooth characteristic; and pushing the identified first Bluetooth characteristic for reading by the user device.

First claim

What is claimed is:

1. A method for transmitting data between a peripheral device and a user device via a Bluetooth Low Energy connection, comprising:
at the peripheral device:
transmitting data to the user device in a simulated data stream, the transmitting comprising:
identifying a first Bluetooth characteristic for writing data, wherein the first Bluetooth characteristic has an “indicate” property enabled and the first Bluetooth characteristic has been exposed by the peripheral device to the user device in a current connection event;
determining a respective data size of the first Bluetooth characteristic; and
dividing a data packet that is to be transmitted to the user device into a sequence of data frames plus zero or one remainder in accordance with the respective data size of the identified first Bluetooth characteristic, including:
in accordance with a determination that the respective data size of the identified first Bluetooth characteristic is a first size, dividing the data packet into a first sequence of data frames each having the first size, plus zero or one first remainder; and
in accordance with a determination that the respective data size of the identified first Bluetooth characteristic is a second size different from the first size, dividing the data packet into a second sequence of data frames each having the second size, plus zero or one second reminder; and

for each of the sequence of data frames:
writing the data frame to a respective value for the identified first Bluetooth characteristic; and
pushing the identified first Bluetooth characteristic for reading by the user device.

2. The method of claim 1 , further comprising:
padding the reminder to obtain a padded remainder have a respective size equal to the predetermined size of the identified first Bluetooth characteristic;
writing the padded reminder to the respective value for the identified first Bluetooth characteristic; and
pushing the identified first Bluetooth characteristic for reading by the user device.

3. The method of claim 1 , wherein pushing the identified first Bluetooth characteristic for reading by the user device further comprises:
requesting the user device to read an updated value of the identified first Bluetooth characteristic through an indication operation.

4. The method of claim 3 , further comprising:
for each of the sequence of data frames:
receiving a respective confirmation for reading of the identified first Bluetooth characteristic from the user device, wherein the writing and the pushing of a next data frame in the sequence of data frames is performed in response to receiving the respective confirmation until no more data frame or remainder in the data packet remains to be transmitted.

5. The method of claim 4 , wherein the user device reassembles the respective values read from the identified first Bluetooth characteristic into the data packet.

6. The method of claim 4 , wherein the data packet includes a message originated from the peripheral device and targeting a support service provider of the peripheral device.

7. The method of claim 4 , wherein the data packet includes a message originated from the peripheral device and targeting a user of the user device.

8. The method of claim 4 , wherein the data packet includes a message originated from the peripheral device and targeting a social network contact of a user of the user device.

9. The method of claim 8 , wherein the social network contact of the user of the user device is another user.

10. The method of claim 8 , wherein the social network contact of the user of the user device is another peripheral device.

11. The method of claim 1 , further comprising:
at the peripheral device:
receiving data from the user device in a second simulated data stream, the receiving comprising:
receiving a sequence of write requests from the user device to write to a second Bluetooth characteristic for receiving data, the second Bluetooth characteristic having been exposed by the peripheral device to the user device in the current connection event;
in response to receiving each of the sequence of write requests, reading a respective value in the second Bluetooth characteristic; and
in a read buffer of the peripheral device, storing the respective value that has been read in response to each of the sequence of write requests; and
reassembling the respective values stored in the read buffer into a second data packet.

12. The method of claim 11 , wherein the second data packet is an instruction originated from a support service provider of the peripheral device and targeting the peripheral device.

13. The method of claim 11 , wherein the second data packet is an instruction originated from a communication server of a social network client application executing on the user device, and targeting the peripheral device.

14. A system for transmitting data between a peripheral device and a user device via a Bluetooth Low Energy connection, the system comprising:
one or more processors; and
memory having instructions stored thereon, the instructions, when executed by the one or more processors, cause the processors to perform operations comprising:
at the peripheral device:
transmitting data to the user device in a simulated data stream, the transmitting comprising:
identifying a first Bluetooth characteristic for writing data, wherein the first Bluetooth characteristic has an “indicate” property enabled and the first Bluetooth characteristic has been exposed by the peripheral device to the user device in a current connection event;
determining a respective data size of the first Bluetooth characteristic; and
dividing a data packet that is to be transmitted to the user device into a sequence of data frames plus zero or one remainder in accordance with the respective data size of the identified first Bluetooth characteristic including:
in accordance with a determination that the respective data size of the identified first Bluetooth characteristic is a first size, dividing the data packet into a first sequence of data frames each having the first size, plus zero or one first remainder; and
in accordance with a determination that the respective data size of the identified first Bluetooth characteristic is a second size different from the first size, dividing the data packet into a second sequence of data frames each having the second size, plus zero or one second reminder; and

for each of the sequence of data frames:
writing the data frame to a respective value for the identified first Bluetooth characteristic; and
pushing the identified first Bluetooth characteristic for reading by the user device.

15. The system of claim 14 , wherein the operations further comprise:
padding the reminder to obtain a padded remainder have a respective size equal to the predetermined size of the identified first Bluetooth characteristic;
writing the padded reminder to the respective value for the identified first Bluetooth characteristic; and
pushing the identified first Bluetooth characteristic for reading by the user device.

16. The system of claim 14 , wherein the operation of pushing the identified first Bluetooth characteristic for reading by the user device further comprises:
requesting the user device to read an updated value of the identified first Bluetooth characteristic through an indication operation.

17. The system of claim 14 , wherein the operations further comprise:
at the peripheral device:
receiving data from the user device in a second simulated data stream, the receiving comp
