Default UDP Connections

Please Login to Remove!

Has anyone successfully communicated with an external system via UDP on the BlackBerry? Reason I ask is all the list of APNs in the FAQ section indicate they support TCP/IP. Does UDP/IP work also?

Thanks in advance,

Chris

Default UDP only available through APN provided proxy?

After doing some forum searches it appears that UDP on the BlackBerry devices is only available through a APN provided proxy. Meaning that the connectivity between the BlackBerry device and the APN is always TCP/IP and the proxy must provided a UDP proxy. Is this correct?

Does this help? I had started looking into how to send a UDP packet from the Blackberry but I got side tracked by another project and haven't investigated it any further than this post I made.

Is it possibe to send a UDP packet with a socket connection

Thanks for the reply. Unfortunately, I did find that thread. I believe that UDP is not directly supported on the BlackBerry device. It appears (based on what I have read) that UDP must be proxied at the carrier APN. Does this sound right?
