Hi guys,
my Setup:
HC12 modules (4)
Micro,
Nano,
Uno
IDE on a Macbook
I downloaded a sketch to configure the HC12 modules, which worked flawlessly. I played with the settings and finally reseted them to factory settings.
After the reset I again successfully connected them.
Now I tried the same some days later and they won't connect at all.
I did not change the sketch, neither did I change the pins.
Also did I check the pins like a trillion time, and ripped everything apart to use fresh cables and all that.
To check if the IDE might be faulty I tested it on my old grumpy PC laptop and got the same results. No connection at all.
With none of the 4 modules that worked the day before.
Is there anything I missed here?
This is where I got my sketch from (in german admittedly):
https://arduino-projekte.webnode.at/meine-projekte/parametrieren-des-hc-12/
It's too long to post here.
Maybe someone has an idea what might be wrong. I don't get it.
Thanks.
Cheers
