I'm guessing that URC is a feature that I need. I'm developing software to interface with a SIM7600G modem and using esp-modem component. it works as expected however, since many AT commands do not respond immediately I'm unsure (no documentation or help on web) how to be get actual AT command response when it take time to respond, or when I can be notified that modem has received an SMS text, for example.

Based on reading the issues below I feel that the URC feature will help, but there's very little documentation and the example given in the issues is for some "SHINY" configuration. The esp-protocol examples for esp-modem demonstrate it but I'm unsure how to configure and use for the sim7600.

Please help Thanks
