[AVR] Usart not receive fingerprint Module R305 response in atmega32

[bhura112]

Hay Friends..
I am using Fingerprint Module R305 ,when i transmit GenImg[12],seach[] to fingerprint module by atmega32 it's work properly but if i save response of R305 module it's not receive and micro controller waiting for incoming data ... I am confused what i do
....Plsz frdsz help me
