![]() Proprietary protocols have the advantage of limiting packet overhead as per application requirements, and hence, may be able to support higher throughput. ![]() However, application throughput is only 256kbps due to overhead. From a Digikey comparison of Bluetooth and RF technologies:īluetooth LE supports an over-the-air data rate of 1Mbps, which is sufficient for wireless HID applications. There is some evidence that Bluetooth LE (low energy) has a particularly high protocol overhead and a 1mbps connection only has 256kbps of usable bandwidth. The speed after protocol overheads is going to be a bit lower, but I would be surprised for it to be more than 60% of the signalling rate which seems to be what you are seeing. This means potentially between 128 to 384kiloBytes person second at the relevant signalling rate. ![]() Unless both devices support Bluetooth HS (High Speed - essentially a Bluetooth negotiated WiFi connection) then Bluetooth supports anywhere from around 1Mbps to 3Mbps (EDR) depending on version.
