Yes, with Connection Event Length Extension and 400ms connection interval you will have a slightly higher maximum throughput than with a lower connection interval. The reason for this is lower overall packet overhead with the 400ms interval, but with a value above 400ms any further gain is minimal. In addition, if you lose a packet, you will have to wait the whole connection interval before sending the next packet. So for maximum throughput a higher connection interval than 400 ms is not recommended.

Yes, I mean the connection interval, you are right but I have seen on the specification that if we enable the Connection Event Length Extension we could reach a maximum throughput of ~700Kbps with a connection interval of 400ms.

Hi,

There is unfortunately no built-in filtering function for the log-file generation. But, many editors have quite powerful filtering mechanisms, so you should be able to filter out the information you want. A start could be to filter out all the lines that don’t have the word INFO, this can easily be achieved using Notepad++’s bookmark mechanism. Excel should also be able to do this.

What time interval are you referring to? Connection interval? Usually a lower connection interval will result in higher throughput.
