Hello,
We are using BlueZ-4.101 and the device is paired with an LE proximity
device.
When "DiscoverCharacteristics" is called, after creating LE connection it is
trying to encrypt the link which fails with "Pin or key missing".
< HCI Command: LE Start Encryption (0x08|0x0019) plen 28
0000: 40 00 cb 2e 2a ec a1 c5 3c ad 2d d5 02 dc 91 a5 @...*...<.-.....
0010: d7 7b b0 aa 82 ef cb 32 31 ce 4e 6f .{.....21.No

LE Start Encryption (0x08|0x0019) status 0x00 ncmd 1
HCI Event: Encrypt Change (0x08) plen 4
status 0x06 handle 64 encrypt 0x00
Error: PIN or Key Missing
Any idea why it is failing?
One thing I noticed is during pairing also this encryption is being done
and it succeeded.

But both the encryption packets are different. Is it expected?
Thanks,
Jaganath
