    Re: HC-12 error correction

    From my point of view is working fine.
    You can try out my configs above. Also increasing the VCC of the TX to something like 4,5V will improve the transmission.

    Re: HC-12 error correction

    Hi;

    I use those modules a lot.
    The 1000m are of course in best of the best conditions, but 50m are very bad.

    Re: Bought this RF modules

    Yes, those modules suck!

    Sim, esses módulos não valem nada, falham muito. Experimenta os que eu te disse, os HC-12. Comprei uns poucos e funcionam muito bem, e são mais baratos.

    Re: Bought this RF modules

    Hi Cesar;

    Yep, the configuration sometimes disapears from those RF module. I really recommend the HC-12. They are cheaper than those, and works better.
    By the way, are you brazilian or portuguese?
