nRF24L01 interrupting Spektrum/Futaba/... Transmitter?

Hey guys

I want to build my own remote and receiver for my RC hovercraft based on Arduino. Therefor I just ordered 2x nRF24L01-modules. As far as I imagine it should be no big deal to communicate between the two Arduinos/nRF24L01-Modules.

But I'm concerned about interrupting other collegues flying their planes with Spektrum/Futaba/other-Remotes who also use 2.4Ghz-transmitters. Normally you have to bind your craft/receiver to your remote so that they do not take control over another craft. But I haven't found a tutorial where you could/have to bind two nRF24L01-modules.

So I have one question. If I follow this tutorial:

Do I interrupt/interfere with someone else' communication? I dont want to take down their planes... :zipper_mouth_face:

Thanks for any tips! :slight_smile:

You don't need to bind nRF24 modules but you do have to select a channel (frequency) and give the receiving unit an address. It will only respond to messages that are on the correct channel and using the correct address. I suspect the binding process is just a mechanism so the Tx and Rx can agree on an address.

As a public service just make sure that your system does not transmit more often than is necessary.

Don't worry about the Spektrum devices. All these things are designed to share the world with other 2.4GHz devices including WiFi and Bluetooth. AFAIK the Spektrum devices use Cypress transceivers which are similar to the Nordic nRF24s but are not compatible with them.
