The peripheral and central needs to be paired and bonded once, and then be in a "trusted" state. We are using the Bluetooth 4.2 LE Secure Connections (ECDH) feature for this. We have configured it for Just Works on both sides. The issue is that we cant get the initial bonding process to work, apart from public key exchange seems to work. We have tried a million things, and are kind of stuck. We can only see, from our traces, that the Central (DA14585) sends a "Pairing Failed: Invalid Parameters" right after the Pairring Confirm message is receved from the Peripheral, and then the connection is terminated. Have a look at the PDF attached to this ticket.
We are a bit in doubt of how the Dialig DA14585 SDK 6.0.10 actuallty supports the LESC feature and in what scale. Is there any possibility to trace, debug or investiate the origin of the problem?
I have attached a Wireshark trace of the issue.
Kind regards
