@ GVZ - Have you tried my code ([url]https://www.ghielectronics.com/community/forum/topic?id=18327&page=1#msg182037[/url])? Does the LED blink?
I will try it!! but I don’t think it works, when you put the CTS high and try to write all the system lock, all the threads stop. I don’t know if this change on C#?.
I cannot test my code myself at the moment. But if LED stops blinking then this issue was reintroduced. I do remember testing my code with some older SDK and it looked like it was fixed.
@ GVZ - We will take a look and see if it was reintroduced.
I run Iamin’s code and they look fine for me, the led always blinks no matter CTS high or low.
That code is good for testing this problem.
