Bluetooth device and data scheduler
A method and device for wireless data transmission are described. A device receives sets of sensor data associated with respective sensor measurements for a vehicle. The device determines a priority for each of the sets of sensor data based on an amount of data stored for that sensor measurement in a number of data queues, and selectively stores each of the sets of sensor data in one of the data queues based on a threshold data throughput rate of a wireless network and the priority of each set of sensor data. The device transmits, to a second computing device via the wireless network, at least some of the sets of sensor data from the data queues based on a current data throughput rate of the wireless network and a priority level of each of the data queues.
