Answering here, the problem is related with a dual device. Due to it is
dual, the pairing is being done for the BDEDR bearer and not for the LE
bearer. As tricky option, what I have done is disable bdedr. Another
tricky option is create a lecc connection (hcitool lecc bdaddr) and then
lunch the pair process.
So, without doing any "tricky" operation, does anyone know if it is
possible to force the authentication in one specific transport layer
(BDEDR or LE)? I have seen that normally it is picked the "last used",
but I would like to know if there is a way to specifically indicate it.
So, in my case (without the trick), when I start a GATT server with
security high, the connection is rejected due to authentication fail.��.n��������+%������w��{.n�����{��� �^n�r������&��z�ޗ�zf���h���~����������_��+v���)ߣ�
