Currently the JN517x is only supported with LPCXpresso IDE, not MCUXpresso IDE. The version is defined in the JN517x SDK Release Notes – which is LPCXpresso IDE v7.9.2 build 493 (LPCXpresso_7.9.2_493).
For more information on JN517x, visit : Support Resources for JN517x MCUs|NXP
And for further assistance on JN517x, I would suggest posting in the Wireless Connectivity forum: https://community.nxp.com/community/wireless-connectivity
