Sorry for a late reply. I though I had replied to this already.

Yes, the submit_multi pdu is implemented. Please check with you gateway provider whether the submit_multi pdu is supported.

Let me know if you need something else.

Hi Ben,

Thanks for you reply. Your work is great!!

I reviewed the source code release ad35e32d9dfe of may 9 and I can't find 'Submit Multi' implementation. Maybe, this is not the last version.

On the other hand, we are working in a SMSC Multiplexer  based on your smpp protocol implementation. I hope show it to you when we had finished.

Hi Luys,

That is the latest release so far. I am sorry that I didn't mention that some of PDU implementations did not make to the final source code, and this includes the 'Submit multi' pdu.

This is partly due to the lack of testing platform since most SMSCs implements only a certain set of PDU commands.

However, I would really like to know of your progress and whether there are any serious issues you are facing. If there is anything you think should be added to the library, I would

be more than happy to learn about it!

When you have finished your project, I would like to take a look.
