Wide broadcast from a NRF24L01

I want to know what the feasibility is of making a wide broadcast on a NRF24L01. Specifically, I want to transmit to maybe 20 NRF24L01s at the same time. Cross communication isn't needed in this application. I want to broadcast like a esp8266 or esp32 (without the battery drain). I just want one transmiter and like 20 receivers. Even if I have to manually address each one.

Is this possible? Has anyone tried it? How well did it work?

yes that should be possible, i don't have 20 receivers, only 4 or 5 all receiving the same signal no problem.

All you need to do (if you are using rf24) is disable auto acc on receivers and transmitters

setAutoAck(false);

and set all the receivers to listen to the same address as the transmitter uses.

and maybe send the message a few times just to make sure that all pick up the message.

Best of luck!
