Finally cracked the code on using HiLetgo HC-12 433Mhz wireless modules with PICAXE microcontrollers! If you are getting constant "0xFF" errors, garbage data, or the modules just won't talk, this video is for you.
In this video, we cover:
Using AT Commands to factory reset modules via USB-to-TTL.
Wiring "Flexi-Pins" on the 08M2 to avoid the programming bootloader trap on C.5.
Stop fighting your UART signal and get your wireless project 100% reliable!
