I have two NRF24L01+ modules which are transceivers, but for my project I would like to send a very simple signal from one of these modules to the be read by the other.
That would've been very simple if I had an Arduino on each side but due to power consumption constraints as well as size, cost and practicality, the transmitting side won't have one. Would it still be possible to do this?
To clarify, the message itself is not important and can be set in stone, it will never change. I really just want to detect on the receiving side (which will have an Arduino) that the transmitter is in fact transmitting. Transmission will be triggered by a push-button.
Ideally I would have a way of identifying my particular transmitter from others on similar frequencies but I am not too precious about that.
