Make multiple transmitters with nrf24l and one receiver with nrf24l?

Question

Arduino

Let's say I have 20 nrf24l radio modules with arduino and sensors that transmit data to one receiver with arduino and nrf24l, how can I implement this because it says that nrf24l combines only 6 devices?

Answer 1

because it is written that nrf24l combines only 6 devices?

Where is it written? Although it may well be, I would, for example, use not only 20, but even 10 nrf24l at the same time, it would never even occur to me.
Obviously, you have only two options:
Correct - replace nrf24l with ESP-01, it's easier and more reliable
Not very correct - configure transmitters in such a way that groups of 5-6 pcs work on different channels. The problem can be if all available channels of the group are very noisy
. Also, if used as an Arduino Mega server, you can connect up to 4 receivers configured for a separate group

Answer 2

General information, I think, can be searched for by the keys "code division of channels" and "frequency division of channels". And then - study the datasheet and application note for the available radio chips.

Answer 3

If there is a task to use Nrf24L01, then ... you can make groups of 6 transmitters and make an arduino "leader" in each group, which will communicate with the same leaders via i2c.
I think the idea is clear. The main thing to keep in mind is that if someone sees THIS miracle of technology, then in his eyes you will become a monkey of the "premature"
Krch model. use esp1 and don't worry
