Issue with NFC_PAIRING_MODE_LESC_OOB

[Roei]

Hi,

I'm using nrF52840 to connect to a PC via NFC. First is was OK, but after that I added an encryption to my application.

In order to do that, I changed the NFC_PAIRING_MODE from NFC_PAIRING_MODE_JUST_WORKS to NFC_PAIRING_MODE_LESC_OOB. In addition, I used pm_conn_secure() to open a secured link after the connection was established.

The result is that now I have a lot of connection problems when I'm trying to connect with NFC pad. I have a suspicious that it has something with the encryption changes.

Does it make sense? Did I forget something?

Thanks!
