how to enable LE_CODED in NCS1.8.0 periodic_adv ?

Question

Hello, 
 NCS1.8.0 Windows10 X64, 
 periodic_adv had set BT_LE_ADV_OPT_CODED and BT_GAP_ADV_FAST_INT_MIN_2 /* 100 ms */ 
 periodic_sync scan info "Prim: LE 1M, Secn: LE Coded, Interval: 0x03c0 (1200 ms)" 
 question: 
 1. why it still Prim: LE 1M? 
 2. why the Interval is 1200ms?

thanks 
 Best regards,

Hi 
 Can you upload the serial log in its entirety so we can see where this information comes from. If it's from a connection parameter update, it might be that one of the devices in the connection does not support Coded PHY for example. Just to make sure, what device are you testing this project on, and what device are you using to scan (and possibly connect to)? 
 To see how the application should be configured to use the Coded PHY, you can check out the Bluetooth: Peripheral Heart Rate Monitor with Coded PHY sample in the nRFConnect SDK. I was not able to spot anything obvious missing, but you might have missed some configuration so it's worth taking a look at our sample I think. 
 Best regards, 
 Simon
