Hi,

Yes, they will be compatible. See this answer.

[pavan]

so that means two different versions will communicate(smart phone BLE version 4.1 and Nordic device version bluetooth 5)?????

Yes, they will communicate just fine, but you will not be able to enable the BLE 5 features(High throughput, Long rage, etc) on the link.
