Possible to fetch some statistical information about a BLE connection?

[rgrr2]

Hi,

is it possible to get some statistical information about a BLE connection?

Background is, that I'm experiencing connection problems (degrading throughput, stuttering connection) if more than one packet/event is used.  With one packet/event connections are (more) constant, nevertheless performance could be better.  So I want to autodetect, if there is a connection problem and then as a consequence reduce the packets/event to one in such a case.

Hi,

Unfortunately, there is no autodetect to see if there is a connection problem. But you can get some statistical information by setting up a timer to see how long it takes from you queue a packet until it is sent. You can see how many connection intervals it takes before the packet is sent, this way you find out if there are any packet loss.

Thanks for the suggestion.  BTW: I did not expect that there is a buildin autodetect feature.  I want to implement this on my own.  My idea was to get a total packet count and a transmission retry count from the softdevice, because it is hard to get this from the outside of the blackbox softdevice (e.g. one cannot distinguish between a packet simply not sent to the central because the central is not ready with a transmission retry).  And if you are not expecting a continuous data stream it is even more difficult.
