ARAVINDAARONE

i tried using sx1272 in communicating with arduino pro mini, with the basic program which is available in the internet i the sites cooking Hacks and after uploading there occurs...

Even after setting the SS pin there also occurs the same error like "Unrecognised transceiver"

My controller is Arduino Pro mini with 5v and again the same error occurs as "unrecognised transceiver"

but in the actual datasheet of sx1272 the supply voltagei is - (-0.5v) to (3.9v) and the operating voltage is - (1.8v to 3.7v) i am supplying 3.5v to sx1272

sorry sir its my fault, i made the connection in wrong way. Thank you for your help.
