First you have to pair your Q with a computer over bluetooth... that can be done by following your bluetooth section in your Q manual.
Then, on your computer, you will find the services that are available on the phone and computer pairing... one of them being OBEX, Object File Transfer... from there you can typically drag and drop or select files to send to the phone over this profile.
It's not really a step by step process as a lot of software is different... If you look for the signs (File Send, Transfer, OBEX, etc key words), then you should be able to easily drag and drop files to your phone... |
