Using Realtime UPD to Send a string

How do I send a string using the Disktop realtime UPD send block

I am using the string compose to build a NMEA like string

I want to send this to a remote computer which is listening

I do not know how to setup the realtime UDP send block to send a string.

I have tried a raw string and a string to ASCII conversion

Thanks

Brian

Hi Brian,

for an example how to send formatted text over UDP using Simulink Desktop Real-Time, please see the sldrtex_streamio shipping example. You just need to change the protocol to UDP, see the sldrtex_packetio example for that.

Good Luck, Jan

this example does not show how to configure the UDP streaming block to accept a string or ascii input

Hi Brian,

The sldrtex_streamio example does exactly that. Please open the Stream Output block dialog and you will see a format string similar to what you have posted. You do not use the Compose block at all. Instead, you send the numeric values directly to the Stream Output block and use the format string that is a parameter of the block.

Good Luck, Jan
