Hi, I recently purchased 2 HC-12 modules (originals) for a project I'm doing that requires reliable comms for ~100m.
These boards in particular have given me a great deal of trouble and I cannot seem to get anything out of them. I am still at the stage of verifying that these modules work and am close to concluding that they don't.
I have follow a lot of tutorials online to try and get these two modules to communicate to each other (connected to separate computers a few meters apart) with no success.
Most recently i set the SET pin to LOW and tried to get some information off of the device, again to no avail.
I tried powering the device straight from the Arduino before putting a capacitor in parallel to the power source/ground.
Any help would be greatly appreciated as I am not sure where to go from here.
Thank you very much.
P.S. I used very basic code from tutorials so don't feel it necessary to post the code here, but let me know if you think it'd help. Same with the wiring, I can upload a picture if needed.
