Explicitly configure Coded PHY (S=2 or S=8) for extended advertising on nRF52840 using nRF Connect SDK (Zephyr RTOS v2.6.1)

[lorao]

On the nRF52840 using ncs/zephyr v2.6.1, how can I explicitly configure the Coded PHY scheme (selecting either S=2 or S=8) for BLE Extended Advertising? Please provide the necessary Kconfig and code configuration steps.

Hi Rao, 
I assume you can do extended advertising with S=8 already ? 
If not please take a look at the peripheral_hr_coded sample. 
Regarding your question, to choose between S2 and S8 you need to use BT_CONN_LE_PHY_OPT_CODED_S2 , please see:
