CC2640: The BLE HID emu kbd example response speed is too slow

Xiaobin Huang

Part Number: CC2640

The keyboard response speed is too slow, almost 1s to send a character if I keep press the button, my 2.5g wireless keyboard could send 100 characters in 3.6s.

If I change the slave_latency and the speed will become faster but there will be a string of error character. How can I modify the example to perform as a real ble keyboard?

What's the modification you have done to the project?
To have quicker response, you should decrease the connection interval.
The slave latency should not affect the response as this is only applied when slave has nothing to send, then it can skip # of slave latency of connection events.
So if there is a key press, the slave should send it out right away, which means the main factor is the connection interval.

Changing the slave latency should not affect the actual string, can you elaborate your setup so I can reproduce it here?
