Image transfer via bluetooth

[tserivdd]

Hi guys!

I was wondering if it's possible to send a png image from one phone to another via bluetooth (JSR-82). I've tried sending Strings and worked fine.

thanks!

Basically it should work. You don't necessarily need OBEX to send files. However, sending files over RFCOMM or L2CAP may need some extra work.

Thanks seppo_fn!

Another question though.. what kind of 'extra work' do you mean? and when i'm going to send the image over the air, what data type should the image be (blog or still png)? Thanks again!

I chosed a byte[]-Array via DataInput-/Output-Stream and it works fine.
After making the connection I transferred at first the Array-size with writeInt/readInt (or sim.) and than the byte-Stream with adequate functions ...

When you want to work with pics from the jar you can read them as byte[].
Also there is no problem with cam-pics: They normally came as byte-Stream (<-videoControl)
Transfer with Image.creatImage ....

Hi,

i know this is probably a bit basic, but how do you change the png image to a byte array? could you apply this to any object, i.e. is it possible to send any object over RFCOMM and L2CAP? could you incluce some sample code please schnejan??

thanks
