Hello. I have this mini-project that I've been doing for a while now. I'm making an RC boat that can be controlled using Bluetooth via a custom Android app. Below is an example picture of the schematic diagram of the connection (PS: Picture is not mine I just found it on Google) and I was thinking if I could change the two (2) HC-05s in the picture with HC-12, a wireless transceiver module that can both transmit and receive data up to 1.8km as stated on some specs sheets. I want to use HC-12 for my project since I need the long-range wireless function of the module, and HC-05 just limits my connection up to a couple of meters away. And as mentioned, I will be controlling the RC boat using an custom Android app. Thank you and have a nice day.
