Particle Photon and Serial Port Read/Write Basics


hi, This example does not work on my photon, do not I see anything on the viper ide monitor, while everything works if use Hello World example.

<span>can you help me?</span>


i tried, it works for me.
The problem i can see is that when you open the serial console you don’t see any printed line because the photon wrote it on the serial bus but the serial monitor is not opened yet.
try to write something on the serial console input line and hit return, you should see the line you wrote replicated by the photon.

see the behavior of my console in the following picture
