Hello,
I am trying to develop a small app to send MMS with my desktop (linux).
So... ppp with my gprs card works and I can connect to the mms APN of my provider.

I can send MMS and everything seems to work.

But when the size of the mms encoded file grows over around 8Kb, I cannot send the MMS anymore.

I use the wap gateway of my provider sending (obviously) a WAP Post. I can see UDP packets to port 9200 (MTU is 1500) but the flow stops at a lenght of around 8800 bytes.

What may be the cause ?

If I use a local WAP Gateway there are no problems at all (but it's loopback interface :-( and MTU is higher)

Thanks for a hint.

Max

/me stupid.

I have to use port 9201 and WTP as transport for larger messages.

UDP is not reliable as is connectionless.

Thanks.
