Is there any limit on the bluetooth share folder in linux either in bluez stack or in obex ftp?

Is there any limit on the bluetooth share folder in linux either in bluez stack or in obex ftp?

[Sasikiran Maddula]

Hi,

I tried to send a file of more than 2 GB using bluetooth in linux. It 
says "Error while copying. There is not enough space on the destination. 
Try to remove files to make space". When I look for more details it says 
"There is 2.0GB available, but 2.8GB required", but the file size I am 
trying to send is 2.8 GB, also in the other end it has more space than 
the file size. I am trying to copy the file from laptop1 to laptop2 with 
a share folder as "x" in laptop2. I used several vendor dongles. All of 
them behave the same way. When I check for the properties of folder x in 
laptop1 it shows as 2.0 GB used and 2.0 GB free. But actually the share 
folder is not filled by 2.0GB, but it is more. I used linux 2.6.28 and 
2.6.31 kernel versions with bluez 4.32. I even verified with 2.6.31 with 
4.32 bluez and 2.6.28 with 4.53 bluez. All of them behave the same way. 
Could some body suggest me where is the issue and how to rectify the issue.

Thanks,
Sasikiran.

BlueZ comes neither with an OBEX server nor an OBEX client. Which client
and server are you using? AFAIK by using standard OBEX FTP the only way
for the client to know the amount of free space in the server is through
the capability object. Maybe the capability object on server contains
false information or then your client is interpreting it incorrectly.

By default Linux comes with obex-data-server. I am using that itself. Do 
you think I need to update that and try. If so can you tell me what 
version has the fix.

Thanks,

neither from Johan or me you will get help on obex-data-server. We are
focusing on obexd and I don't remember it having any of these issues.
