We have a wifi shield you can use directly with OpenMV :

Or you can use I2C or UART and send the data to Arduino. See the following examples in the IDE:

Examples->02-Board-Control->arduino_i2c_slave.py
Examples->02-Board-Control->uart_control.py
Examples->14-WiFi-Shield
Examples->16-Codes

Thank you for your answer.

Is this possible using UART and getting data with OpenMV Qr code example. And send to Esp8266.
Can I use openmv with esp8266 ?

Yes, just pipe the printed text output to the UART.
