摘要
An example method includes receiving, by a first application executing on a primary device and from a second application executing on the primary device, an indication of data to be transferred, wherein the primary device and the vehicle head unit are communicatively coupled via a wireless network connection operating in accordance with a wireless networking protocol; determining, by the first application and based on the indication of the data, an amount of data to be transferred; determining, by the first application, whether the amount of data satisfies a maximum packet size for the wireless networking protocol; responsive to determining that the amount of data does not satisfy the maximum packet size: segmenting the data into a plurality of packets, wherein each packet from the plurality of packets includes an amount of data that satisfies the maximum packet size; and sending the plurality of packets using the wireless network connection.

Companion application 105, responsive to receiving the plurality of packets via transport 109, may combine the portions of data included in each of the plurality of packets into the data (602). In some examples, the portions of data included in each of the plurality of packets may be combined based on a respective segment identifier included in each of the plurality of packets. Companion application 105 may further provide the assembled data to application 104 of primary device 100 for output (e.g., via presence-sensitive display 406 of primary device 400) (604).
In this way, various aspects of the techniques may enable the following clauses.
