It seems that the number of buffers in the controller is limited to 4, so the max number of ble packets that can be transmited from any devide per connecion event is limited to that. But, ovbioulsly, for reduced connection interval values, like i.e. 20ms, just one max size packet is transferred from the peripheral to the central devide per connection event.
It is possible to change the number of buffers in the controller?
Can anyone at sparkfun support team, or any other user confirm this behavioral?. I would really appreciate any help or any comment.
