Hi All, I'm using BTSync for a long time now, there's only one thing I would like to know. I would like to sync my camera roll to my Synology NAS, but I cannot find any info how to configure both the phone and the NAS. I can create a shared folder on my nas, which will provide me a key, I cannot enter this key on my phone, near 'Camera Backup'. on my phone, I can use the share feature, but it looks like this is for windows/osx only. Someone with some more info how to sync ?
