Our EC200U-EU module reports firmware revision EC200UEUAAR03A22M08. Please provide the full Standard AT firmware package for this exact revision, including the PAC file and release notes, rather than a differential OTA package.
We use an STM32G070 connected to MAIN_UART. USB DIAG version and NV information reads work, but the same version query receives no response on MAIN_UART. Does this firmware support DIAG over MAIN_UART? If so, please provide the supported entry/exit procedure and documentation.
Thank you.
