RX TX modules - intermitent communication

[dhouston]

since the TX will jump to a label "value" to get ADC values,calculating average from 16 readings, could this compensate the lcd servicing you mentioned?

Maybe - you might try adding a delay after TX to guarantee enough time. You might also limit LCD writes to only update the display if a value changes.

Maybe i'm wrong here, but i'm starting to think of the possibility that having BOTH RX and TX modules on the same experiment board and having both antenas side by side is NOT the best idea.

Could this be an issue having them so close to each other ?

Possibly - it's difficult to generalize without technical details but the I have had problems sometimes when TX & RX were too close.

I've tryed both but had no positive results.

What bugs me is that i connected the busy output of both modules to a LED.

The receiver module's LED blinks the same as the TX module indicating that is receiving valid data...however the pic only displays sometimes some of the sent values digits
