Hi,

I am not sure exactly what you are asking about, so I will giv you a few hints about how to transfer large amounts of data as fast as possible, since that seems to be what you are after. Please elaborate and specify if you need more specific advice later.

To achieve high throughput, you should try to optimize the following:

• User long packets.
• Use long connection events and connection intervals that match (not too short).
• Use notifications.

You can refer to the throughput example in the SDK. You can also adapt the BLE UART example since you allready mentioned it (it was not clear to me if you wanted to not use the NUS service, or just did not what to use physical UART).
