debian - Automate Bluetooth Pairing/Trusting in Bluez5 -


i've been working on making rpi 2 function car bluetooth receiver , well, except have no idea how automate pairing of bluetooth devices in bluez5. in past would've used bluetooth agent , simple script, seems have gone out window move 4 -> 5. nature of setup means have no kb/mouse on rpi once in car, needs automated setup can scan rpi, , if hard-coded pin correct, trusting of device needs automatically done, no cli input.

i've searched on web seems using bluetoothctl works them, in particular setup i'd able have friends pair own phones, having trust devices rpi out of car isn't ideal.

i'm not sure why using simple script not possible bluez5. think can it. below 1 example how.

download bluez5 source , edit test/simple-agent. comment out lines of code shown below:

def requestauthorization(self, device):         print("requestauthorization (%s)" % (device))         #auth = ask("authorize? (yes/no): ")         #if (auth == "yes"):         return         #raise rejected("pairing rejected")

what remove prompt authorisation , accepts pairing request.

can start simple-agent noinputnooutput capability uses simple pairing , go through above code path:

./simple-agent -c noinputnooutput

after should able pair rpi without user prompt or pin.

note 1 example of can do. if wanted have hard coded pin instead of simple pairing edit appropriate section of same simple-agent code that. i'll leave exercise you.

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
