print("Dragino Uart Test started\n")while1do
serialin=io.open("/dev/ttyS0","r")
print(serialin:read())--print the data
serialin:close()end
I read the serial port but I receive an echo too and the read() waits until a new line character to return.
There is any other way to read from a serial port ?
Thank you for your help, I appreciate it.
