Posted on March 18, 2015 at 00:35We have notifications that we want encrypted, so we set the following flags
uint8_t charProperties = CHAR_PROP_NOTIFY|CHAR_PROP_READ;
uint8_t secPermissions = ATTR_PERMISSION_ENCRY_READ;
Now using something like BLE Scanner on Android doesn't trigger a pairing until the characteristic is specifically READ. Receiving notifications works without any pairing, thus seems unencrypted.
How do we force an encrypted link for notifications? There is no ATTR_PERMISSION_ENCRY_NOTIFY
Do we have to use Aci_Gap_Send_Pairing_Request() to request a pairing? Will the notifications be encrypted then? Is there an easy way to be sure of that? Is there a general ''this link is encrypted'' state that can be queried?
Thanks!
