I pretty new to Arduino and I need help to clarify some things.
First, I want to make an Arduino controlled RC airplane but I don't know what communication module to use. I did some research and found three options.
1. Hc 12 Bluetooth: It has a decent range of about
1.8km, buy suffers from delay(it can't be used on
fast rc cars or airplanes)
2. Nrf24I01: About 850m in open space, uses
2.4ghz which perfect for RC planes but doesn't really work through walls. 3. Lora: has a range of up to 10km but I didn't read on it that much.
So my question is: which one is better to use in a mini uav. I have no problem with mounting an antenna on top of my building. Will any of these work or is it better to use a wifi module connected to a modem which gives it internet access so that I can control the plane over the internet.
