Hi all,
I'm not usually one to post and ask for help, but I'm having some trouble with some HC-12 modules and can't find the issues I'm having online.
I am trying to connect to the HC-12 module by the HC-12 Config Utility but keep getting junk back, see image attached.
I have VCC connected to a 5V regulator through a 1N4001 diode and a 1000uF capacitor
GND connected to ground or 0V
TX on the HC-12 connected to RX on my serial converter
RX on the HC-12 connected to TX on my serial converter
SET connected to ground or 0V
I have tested my serial converter by shorting out the TX and RX pins as described in this link (click here) and it seems to be functioning properly, I have also checked the baud in device manager and its set to 9600 with 8 data bits, 1 stop bit and no parity.
Thinking the HC-12 modules may be faulty, I purchased more from a different vendor on Amazon but I'm getting the exact same issues.
On a side note, I have 2 Picaxe 18M2 successfully talking to each other by means of serout and serin, this was via a physical wire, I have also attached a 433Mhz transmitter to the output 18M2 and a receiver to the input 18M2 and again, this worked exactly as I expected, however I am having some trouble when trying to use the HC-12 module, I read that they will work straight out of the box on default settings, but the data received by the receiving 18M2 is not what was sent.
Have I bought faulty units from 2 different vendors or does someone with more knowledge know what I'm doing wrong?
Thank you for your time reading this.
Kindest regards,
Mark.
