Update on this: we haven't been able to fully solve/implement this functionality yet. Currently, we are still trying to figure out how best to work with NINA-FW when it receives a response payload that is 5744+ bytes in size. When this happens, the ESP32 NINA-FW stops responding to our future communication requests - it still thinks it's waiting for the end of the issued protocol command GetDataBufTcp.
