Application in embedded C (emulating android app commands) for wifi module -- 2

An application in embedded C emulating an android app to send wifi commands to a wifi enabled photo camera. The android app connect with camera as DLNA client (the wifi connection is ad hoc and the camera is the base station) using UPNP protocol, when the android device connects with the camera can send commands to control it remotely. It is necessary to decompile or disassembly a .so file containing all the commands to use it in the new firmware, the other way is sniffing the wifi traffic between the two devices. Can be used any plattform (arduino, MCU, etc) and if possible a cheap wifi module (esp8266, etc).
