Daniel,

Thanks for the response. I'll take a look tonight and test out with the additional parameters.

I do have some questions on the parameters.

For the second to last parameter "Length of Data" Are those 2 bytes an unsigned short meaning maximum data size of 64K?
If so, can I call this method in a loop to chunk on 64K to a file by incrementing the index?
Lastly are the 4 bytes for Index an unsinged int?

Thanks!
-Dean

Hi Dean,

Yes, the Length of data is an unsigned 16 bit value and the Index is an unsigned 32 bit value. You'll be able to upload data in 64K chunks so long as you keep track of the file index.

Cheers,
Daniel

Hi Dean,

The ability to create folders hasn't been released to the public just yet, but we will implement it in the next firmware revision release. Once the new firmware is released, I can provide an example on how to create your own folders and directories.

Ok thanks....I'll work with the directories at hand for now. Additionally a method to delete files would be helpful as well.

thanks

Thanks

Hi Dean,

That's great to hear.

I'll talk to Ray (Our software designer) to see if we can give you a pre-release firmware revision.

Cheers,
Daniel
