Coded PHY support in nrf52833 in NCS

[Kawingwu]

Hi, 

I am trying to adding a coded phy support on my device in NCS project. 

once I added CONFIG_BT_CTLR_PHY_CODED=y in my config , the ROM size will add more than 7kB , it over my expected. 

does any small size option I can using for it?

I only need to change the phy during the connection, no advertising in coded phy,

Thanks

Hi Wu Ka Wing, 
Have you tried to set 

CONFIG_BT_CTLR_ADV_EXT=n
CONFIG_BT_EXT_ADV=n

CONFIG_BT_EXT_ADV_CODING_SELECTION=n

To see if it reduce the size of the flash ? 

The issue is that there is only a few options with the controller. When you turn on CODED PHY most likely it would include also the code for extended advertising (in the controller).
