BC127 Max data rate in SPP mode

We are using SPP for a file transfer in data mode. We currently achieve about 100kbps throughput rate using ~5MB files. We were expecting to achieve >500kbps, and the BC127 data sheet claimed 700 kbps. We are wondering if and how anyone has achieved these higher rates.


Generically speaking BT is not great for file transfers, I have never really been able to achieve a high data rate when sending files/data over the link either with the BC127 or for instance my smart phone to a PC performing a file transfer so I think from experience this is more a tech limitation than a unit one.



You can achieve higher throughput rate (>500kbps) when the High Speed feature is enabled (see HIGH_SPEED config). Note that when High Speed is enabled, the audio is disabled.
