BLUETOOTH MODULES BLUETOOTH LATENCY AND DATA Application Note
This document describes and presents the results from a series of tests to determine overall Bluetooth data throughput, given inherent latencies present in a packet-based protocol such as Bluetooth.
This transfer protocol results in a lot of data in one direction and minimal data in the reverse direction. One device sends a single byte acknowledgement, and the other takes this acknowledgement as a cue to send a large packet. One protocol which behaves in this fashion is Xmodem.
This document describes the creation of a test procedure, which uses an application on a Windows PC to measure the latencies and throughput, and makes suggestion as to how the overall data throughput can be increased.
