Bonding fail and i don't know why

[annapalu]

Hi All,

sometimes i have a problems with bonding: the Nordic APP said "Couldn't pair with xxxxxx because of an incorrect PIN or passkey".

Why i have this errors? What means?

i try to delete bonding information on both side (phone and nordic board) but continues to reject the passkey.

I would that if this errors occurs the bonding procedure can be done again.

Thanks, Anna

How often do you get the error? Are you able to connect sometimes?

Is this the settings you have set in your application?

sec_param.bond = true;
sec_param.mitm = false;
sec_param.lesc = 0;
sec_param.keypress = 0;
sec_param.io_caps = BLE_GAP_IO_CAPS_NONE;
sec_param.oob = false;
sec_param.min_key_size = 7;
sec_param.max_key_size = 16;
sec_param.kdist_own.enc = 1;
sec_param.kdist_own.id = 1;
sec_param.kdist_peer.enc = 1;
sec_param.kdist_peer.id = 1;
