Apache Mynewt Passkey Authentication

[Aditya Xavier <ad...@me.com>]

Hi all,

I wanted to create an application which would request a Mobile connecting to it a Passkey which when provided correctly would allow the gatt connections to work.

1. Is this even possible ?
2. How do I achieve this, I have gone through several examples like btshell etc but could not figure out the direction.


Thanks,
Aditya Xavier.

Hi,

Please have a look on
https://mynewt.apache.org/network/ble/btshell/btshell_GAP/  at Security part

Regarding your questsion:

1) yes
2) In example below my device is peripheral with iocapa=DisplayOnly. We are
already connected with connection handle = 1.

* security-set-data mitm_flag=1 io_capabilities=0 our_key_dist=7
their_key_dist=7 bonding=1 sc=1
* security-start conn=1

After this you should see on the console:
` passkey action event; action=3'

Here is actually a place where we should improve with documentation.
Action=3 means Display, but btshell does not generate passkey for you.
Instead you need to provide it by calling:
auth-passkey conn=1 action=3 key=<your key e.g. 111111>

Then provide same on your phone and you are done.

BTW. Action types you can find in ble_sm.h

Hope that helps

\Łukasz
