<![CDATA[Bluetooth MITM Protection (BLE)]]>Is there a way using the QBluetooth Library to support MITM protection as part of the bluetooth low energy protocol? I am developing an app for an embedded device and both in Linux and on the device I see that when I try to bond using QT it requests pairing using no MITM. Some of my desired peripherals requires MITM to pair.

I see this packet when I try to pair:

< ACL data: handle 1025 flags 0x00 dlen 11
    SMP: Pairing Request (0x01)
      capability 0x03 oob 0x00 auth req 0x01
      max key size 0x10 init key dist 0x00 resp key dist 0x01
      Capability: NoInputNoOutput (OOB data not present)
      Authentication: Bonding (No MITM Protection)
      Initiator Key Distribution:
      Responder Key Distribution:  LTK

Thanks,
Z

The Linux system is Ubuntu 16.04 with QT 5.5 and Bluez5.
