ESP-13 integration with Arduino Uno

Hi Colleagues,

I need your support with Wire library to communicate between Arduino and ESP-13 to sensor data. I have read hundreds of documentations, however, the issue that ESP-13 (master) can send data to Arduino (slave). However, no data received from Arduino to ESP-13 when ESP-13 requested a data!!!

This is a Blynk forum… not a random Arduino/ESP troubleshooting forum :stuck_out_tongue_winking_eye:
