I’ve been tinkering around with the BLE (Bluetooth Low Energy) connectivity classes quiet a bit lately and haven’t been able to make it transfer data any faster than 1KB / 5 seconds. I believe, in the documentation, it says the max speed is 60 bytes per 20 milliseconds. With data transfer and counting the Ack transfer after each set of packets, I believe we should be able to go as fast as 1.5KB per second. So my code is around 7-8 times slower than it should be.

I’m just wondering if anyone has been able to do data transfer in BLE as fast as the documentation says it should be able to do. What sort of speed are you getting if faster than mine?

Thanks a lot

    see at the guidlines of apple and you will see that a connection update request is required to speed up your connection.
