Do you have the UDS-10 set to telnet or raw? Do your callers have v4.x WiModem232 firmware? It could be that they have the older firmware, which did have issues (depending on the router). I found a bug in the TCP stack handler library for the ESP8266 (the WiFi module I am using for this product). Depending on the router and the packet size being sent, the packet could get split and that had a bug that was causing data to be dropped. I spent 250+ hours making a new TCP handler to fix this issue. So, ask your users if they are using the latest version of the firmware.
