At
https://wiki.teltonika-gps.com/view/Codec#Codec_12 it is written that some types of devices support sending SMS via GPRS via UDP. Can you tell me how the interaction takes place? The instrument sends a data packet. Do we send him an acknowledgment of receipt of him and then send the package to Codec12 ? But the big question is what to do with the answer? Where will he come? When it works over TCP, everything is clear - there is the IMEI of the device in the first packet. And how it happens on UDP? Maybe there is some example of sending a command and receiving a response via UDP?
