I built rc lawnmower, using flysky rc controller and sabertooth driver. It works good, except there is data i need to collect from my sensors and sabertooth driver. I have arduino setup to collect data, I planned to relay it back to a wireless read out.
I ordered these Nrf24l modules, but I just realized - my rc controller works on 2.4 ghz. So I guess the two streams from my RC controller and arduino will interfere.
I was wondering if anyone had advice for a solution. I like using my rc controller, is reliable. I thought i could just route my rc controls through the NrF24l device, but the flysky transmitter already has a bunch of functions i already use, and it would take me a while to re-make my own controller.
You should be able to choose a channel for the nRF24s that does not conflict with the RC system. Before changing channels try the default channel - it may work.
Dozens of things in everyday life use 2.4GHz and manage to work alongside each other.
Why not use your nRF24s to do all the wireless stuff and dispense with the RC system?

The R/C controller already has the sticks, switches, and tuning interface to configure whatever channels and signals I need with easy way to change them immediately. I do not have any desire to re-create something that I already have that works just perfect.
My problem is, I can't receive and analyze sensor data with the RC controller - it has a "telemetry" system in it that I have to hack the protocol, and be limited to the data on the controller screen with no option to log or tag alarms.
I just figured out how to hack the I-BUS receiving protocol, so I can just translate the data stream from the hardware of the sticks into the Arduino. I'll process that data to control the Sabertooth motors. I have plans to add the compass, accelerometer, gps, obsticle sensors, and write some fancy software to cut the lawn automatically, or chase neighbor's dog down the street, and ride the sidewalks up to pizzeria to deliver my dinner back to me.
