Default Wireless (Bluetooth) Compact Flash compatible with Digi Cams

Hi all,

Ive just found a site that sells Bluetooth CF product for 30 ($60), it states that these can be used with PDAs for file transfer so would it be possible to use this with Digi Cams? If not then surely the firmware can be edited to allow the file to be just transferred to another device such as a laptop?

Just a thought.....

Ignoring the power concerns (would it drain the camera more than a CF would?) you have to consider the antena. I don't know about the card in question, but some have the antena sticking out of the card. This would get in the way of the door over the CF card in the camera body.

Are you going to do that or wait for the OEM/manufacturer? :lol: :lol: :lol:

I did wonder once, whether a wireless CF card could be emulated with a smaller amount of memory acting as cache, which had an address code and could automatically talk to another card or device like a wireless image tank within range and a matching code.

The camera card would transfer everything coming on to it, if the buffer filled because you were out of range, you'd get the normal card full message, but once close to your base station, the files would get moved off. Obviously you could do wireless in a new cam, but using a card format allows other portable devices to work in the same way.

Hello??? Any telecom folks here...

While almost any CF card can follow the Compact Flash Association guideline for electrical interfaces & power, there's more to this than just sticking in a BlueTooth/Wifi CF card. Basically you are only getting the Phy and possibly the Data layers, what about the remaining OSI stacks? :lol: :lol: :lol:

... Consider the following example. An application forms a packet of data to be sent; this takes place at layer 7. As the packet descends the stack, it is wrapped in headers and trailers as required by the various protocol, until having reached Layer 1, it is transmitted as a frame across the medium in use. Upon reaching device B, it reascends the stack, as the device strips off the appropriate headers and trailers, delivering just the application data to the application...

NHL ... your clearly out front in your advice about cards! I wasn't thinking of standard card off the shelf solution. Use the physical interface and CF card protocol around smaller memory, but add a layer and wireless over the top.

If your cam is used in say a studio shoot mode, all you need then is large cheap HD space and the API in the image tank/laptop/or pc, and forget about card storage to concentrate on picture taking. As image storage gets higher for12Mpix plus or RAW, wireless to HDD would be attractive and cheaper than bigger and bigger in-cam media.

Or to start afresh, cameras with a high speed wireless usb, sending to a remote device what gets captured.

i thought about making a simple IR or RF board that could plug in either side but thats restricted to a pretty low speed of transfer.....looking at 19kb max via IR or 1 or 2kb via RF. You can get faster transferring IR and RF devices but the cost is high.

ill keep you all posted with my findings

Why don't you just get a PDA?

It's a two steps operation (camera -> flash -> PDA/wireless), but much less of a hassle... and you'll have both RF and IR! (or Satellite uplink) :lol:
