connecting to other devices

[not-mounam]

I'm trying to connect with a device (model K14) When I print conn, its value is False, even I am sure that the connection parameters are well!!!
But when I tried to connect with another device (model F18) it connected. What can I do to connect to all the devices? Is there a parameter that I should modify ?
