    Need help in configuring AWS IoT policy which is step 4: Connect to Cloud
    I have logged into AWS, I have successfully completed other three steps.
    Now I don't understand why policy down-down us not working!

    Thanks in advance :)

    you need a valid policy to connect to AWS IoT. do you see mos-default in the list?
    earlier today i pushed a windows version of mos tool that should always have it in the list.
    if your mos tool is older than a few hours, update it and try again.

    Hi rojer,
    Currently I have this Version: 20170223-013339/lsm@c326da37
    mos-default is not shown up.

    Some questions on my mind:
    Do I need to install any AWS SDK for windows ?
    Do I need put ***certificate.pem.crt / ***private.pem.key on to the device using mos ?

    no, you don't need to do anything, mos will create certificates, a thing and (since a couple days ago) a policy too.

    however, you're using an old version. i built one just yesterday, should be 20170315-... - go get a new one from
