Can't connect my iPhone to my NFC Speaker

Hello,

i'm trying to connect my iPhone to the bluetooth speaker by using NFC.

I have tryed several times but without success.

I have even installed a NFC application that can read an write to NFC tags, by trying this application my iPhone can read the information of my speaker, so the NFC of both devices works.

Infact with my older phone, that was an Android, when i barely touch the speaker with my phone it automatically pair the device, and i have payed with ApplePay several times.

What i'm doing wrong?

I have to enable some sort of settings or what?

Thank you
