Your program goes into a loop ?

Without more info that’s the only guess I can make.

Yeah - when/how are you doing the read in the photon app? If you aren’t using a second thread to do the reading you will be making the Photon app behave poorly. You can also go the route of using PtAppAddFd() to perform a select() like callback.
