Hi all I’m developing a BLE peripheral and testing the Security Manager of my device. Either there’s a bug in IOS, or I miss something here.. :) It is set to request security by sending a SMP Security Request after the connection gets established. For the first connection, this triggers the Bonding procedure and results in the key distribution as expected. On the second connection, the device gets an LTK request which it answers with the LTK established before and the connection gets encrypted. After that, a Pairing Request is received. Upon answering with a Pairing Response, iOS sends a SMP Pairing Failed, Unknown Reason (0x08) back. I would either expect not to receive a Pairing Request, or, at least repeat the complete procedure. What do I miss here? The packet log from the device here: https://dl.dropboxusercontent.com/u/5138628/LE-reconnect.pklg Best Matthias _______________________________________________ Do not post admin requests to the list.
