Hi All, I would like to know how to retrive the "bluetooth data transferring speed" in Cocoa. For example, there are two bluetooth enabled cell phone is downloading the data from Mac, I would like to display the dynamic expected downloading time on the two cell phones. First of all, i think i need to get the left file size, and I also need to know the current downloading speed. In Cocoa how to get this value? Thanks in advance.

When transfering files via Obex File Transfer you should provide two callback functions in your delegate looking like this:

- (void) fileTransferServicesSendFileProgress:(OBEXFileTransferServices*)inServices transferProgress:(NSDictionary*)inProgressDescription;

- (void) fileTransferServicesCopyRemoteFileProgress:(OBEXFileTransferServices*)inServices transferProgress:(NSDictionary*)inProgressDescription

You can access informations from inProgressDescription like the current transfer rate using these keys:

     kFTSProgressBytesTotalKey
     kFTSProgressBytesTransferredKey
     kFTSProgressEstimatedTimeKey
     kFTSProgressPercentageKey
     kFTSProgressTimeElapsedKey
     kFTSProgressTransferRateKey


When using Object Push you have to measure time and calculate it yourself.
