ESP8266 and Attiny85

[fuhrer5]

I am planning to connect ESP8266 with Attiny85 in serial communication.

I able to send command from Attiny85 to ESP8266 such as AT command, but Attiny85 unable to read the response.

I checked with dumb Arduino Uno, the response is available.

I wonder why Attiny85 doesnt read the response. Fyi, i use serial.available and serial.read to read the response.
