The modules I used were cheap as chips and I have found them quite reliable...I would recommend them all the way
Well,

i've been working with them all week with NO success!

I've tried using DEBUG/DEBUGIN, SEROUT/SERIN and HSEROUT/HSERIN.

I have 99% confidence in my code because it works when both pics are connected to each other.

Using these modules just doesn't work and i'm out of solutions !
