iOS pairing + LESC

[nrbrook]

I've tried using LESC without bonding, but iOS displays a pairing dialog. I don't think it is possible to avoid this, so the only way to avoid the pairing dialog is to use no link layer security, is that correct?

There is no way to avoid it as far as I know.  Maybe if this is an important feature, you could consider doing the security at the application layer instead.  There is a blog post on that here: https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/intro-to-application-level-security-using-the-ecb-
