+Only works reliable on 3v3.
+Using 5v restarts occur (prints 12> over serial and everytime a new file is created).

+## HC12 433MHz Module
+5v or 3v3.
+Bridge Set pin to ground and power up to enter setup mode.
+Use Arduino IDE to send commands via serial terminal with 9600 Baud.
+AT+RX shows current settings.
+
+Use following commands to setup:
+AT+B115200
+AT+C002
+
+Using channel 2 instead of 1, because 1 receive didnt work with two computers.
