I'm trying to use this utility [first time] to config a pair of HC-12s to a different channel, as I already have the default address in use. It's a very handy utility, though I can find almost no reference to it via Google.
I found reference to the command here: http://www.thebackshed.com/forum/forum_posts.asp?TID=8246&PN=1
When I use to change the channel, i get 5 error messages of the form: invalid response(1), invalid response(3.2), invalid response(3.3), invalid response(3.4), invalid response(3.5)
I am running on Windows 10 x6, using a standard USB cable to an Uno. The wiring config is as follows: VCC to 5v, GND to GND, RXD to pin 4, TXD to pin 5, Set to pin 6
I've also tried connecting the Set pin to GND, as I don't know whether this is necessary or not.
The board also has an 1N4007 diode in series with the power line, and a 1000uf capacitor twixt 5v and GND. Nothing else.
There is a sample program at: http://www.allaboutcircuits.com/projects/understanding-and-implementing-the-hc-12-wireless-transceiver-module/
that should accomplish the same function via use of line commands and I shall try that next. However, the configuration utility is so handy that I would like to have it in my kit of useful tools.
Seeking: Assistance with the graphical configuration utility by someone who knows more than I, or perhaps a better alternative.
