Im trying to decide between Bluetooth and Bluetooth LE. My device needs to transfer 375 bytes per second. Bluetooth LE can send packets of 20 bytes max, so this boils down to about 20 packets per second.
A Bluetooth low energy device used for continuous data transfer would not have a lower power consumption than a comparable Bluetooth device transmitting the same amount of data. It would likely use more power, since the protocol is optimised for small bursts.
Will Bluetooth LE will still be more power-efficient than Classic Bluetooth at this datarate (375 bytes per second)? And if so, at how many bytes/second will it be better to switch to Classic?
