Follow-up to Playing with an Eye–Fi card from Steve’s blog

Yesterday, I thought I understood the Eye-Fi architecture. The Eye-Fi card connects to your PC if it can, and transfers images to the Eye-Fi Center software running there, and from there images go the various online sharing services you’ve configured. If it can’t connect to your PC, the images stay on the camera until it can. And if you want to operate without a laptop, Eye-Fi have a hotspot service you can buy (£25/year) that allows that.

At least, that’s what I thought yesterday. A little experimentation last night and this morning has disproved all that, though. I configured my Eye-Fi to connect to my MiFi, and discovered that with my PC off images still end up in Picasa and in Eye-Fi’s own online storage system, and are eventually delivered to the PC when it is turned on. But that’s what I thought the hotspot service was.

The more expensive cards come with a year’s hotspot service bundled. Mine isn’t one of those. Perhaps it has it by mistake? If any other Eye-Fi users have any idea what’s going on, do please let me know! In the meantime, I’ll continue enjoying functionality I didn’t realise was there…

    all Eye-Fi cards can be configured to store up to 32 Wi-Fi networks. For example, you can store your home Wi-Fi network and your MiFi network on the card and it will try and connect to either of them. You don’t need the Hotspot Access service for this feature.

    Not all Eye-Fi users want (or need) a MiFi-type device with the associated monthly fee, so the Hotspot Access feature is useful for them.

    Additionally, if you set up the Eye-Fi card to send content to an online site (e.g. Picasa) or you enable the “Relayed Mode” setting, and your computer is not on, the Eye-Fi card will send the content to the Eye-Fi server. Whenever your computer is turned on, the Eye-Fi software on the computer will download your content from the Eye-Fi server. So, your computer does not even have to be on at the same time as your camera.

    I hope that helps!


  2. Thanks. That clears up my confusion. I wasn’t expecting this, and am very pleased to discover it works this way. This device keeps getting better:-)
