Cactus Micro Rev 2 sending OSC message

Hi,
Does anyone in this community know how to send OSC messages via the ESP8266 module on Cactus Micro R2?

My project has two HR-C04 Ultrasonic sensors linked to Cactus Micro R2 and I need to send the data of these sensors wirelessly to Processing (on Mac). I have tried existing arduino libraries esp8266-OSC(https://github.com/sandeepmistry/esp8266-OSC) and esp8266WiFi (https://github.com/sandeepmistry/esp8266-Arduino/tree/master/esp8266com/esp8266/libraries/ESP8266WiFi) but none of them worked for my Cactus Micro R2 as it is of an AVR architecture. If anyone knows any existing library (or have successful experience sending OSC messages from the module) please let me know.
Thanks in advance.

PS: I could connect to WiFi at baud rate 9600. All AT commands work.
