This is my following code, the problem I'm facing is that with the code I'm able to get that which protocol the remote im using has like NEC or SONY or AEHA but not able to get the code of the actual value that is received by the mBed on press of a button (that is in the buf variable) kindly tell me where could be the possible problem?

This is my following code, the problem I'm facing is that with the code I'm able to get that which protocol the remote im using has like NEC or SONY or AEHA but not able to get the code of the actual value that is received by the mBed on press of a button (that is in the buf variable) kindly tell me where could be the possible problem?
ON press of a button I get "got>>SONY" and no value in the buf variable?
Where can I be wrong?
