I have answered your other question/thread.

1) I have not tested the example that comes with 3.alpha, but it should be possible to double check the parameters that are being used. In your other question, I have uploaded another example as well that only uses coded phy.

**2)**We are aware that there are some performance issues with coded PHY. We are working on making a fix!

Thanks!

I actually already sent another question on the example code inside the softdevice .zip file (devzone.nordicsemi.com/.../).

Ok. I thought there might be reconnecting (via 1 Mbps mode) implemented, but if not, it is clear to me and I am happy.
Perhaps I ask this way: can you evaluate the performance of the nRF52840 PDK Coded PHY implementation? Is it going to be better in coming (non-preview) releases? This may be a difficult question and you are free to say "no comment" :-). Anyway, I am trying to evaluate the performance of the BLE coded PHY in general and I am currently totally dependent on Nordic's preview kit.

The latest version of S140, S140 v.5.0.0-3.alpha supports advertising and connection establishment on coded PHY. However, the current version of the SDK does only support S140 v. 5.0.0-2.alpha. 2.alpha does not support advertising and connection establishment on coded PHY.

S140 v.5.0.0-3.alpha comes with an example that shows how to connect on coded PHY, the example is inside the softdevice download .zip file. I would recommend you to take a look at that example.

1) When connected on coded PHY, there will not be a change of phy unless it has been explicitly requested. (There is no automatic switching.)

2) Could you please elaborate?
