the remote name request creates a temporary baseband connection and in
that case no other connection request will succeed. Reducing the timeout
for the remote name function is not helping here since it won't send the
remote name cancel in case of a timeout. This is probably a bug in the
library, but also not easy to handle since that command is not always
available.

So first of all you should only request the name for devices with the
correct class (since the others don't matter at all). Then you need to
use a bigger timeout. The name request can take some time. The baseband
needs to page the other side.

Other than that you can add a sleep(1) re-try the connect if it failed.

Regards

Marcel
