https://devzone.nordicsemi.com/f/nordic-q-a/95304/maximum-node-that-1-nrf24l01-can-receiveI want to transmit data from 100 nodes to 1. Is this possible for nRF24L01? The 100 nodes do not need to transmit at the same time. As I found out before, each nRF24L01 can receive maximum with 5 other transmitters at the same time.

It can have up to 6 RF pipes, so for such a setup to work, you should use parts of the payload as an &quot;extended rf address&quot; for each device, and auto-ACKing shall be off (optionally: add manual ACKing in firmware).</p> [quote user=""]I want to transmit data from 100 nodes to 1.[/quote] <p>In order to transmit from 100 PTX to 1 PRX, you will need, in addition to the software implemented addressing (and soft-ACKing); some sort of timing synchronization to avoid on-air collisions.</p> <p>&nbsp;</p> <p>Kind regards,</p> <p>Håkon</p><div style="clear:both;"></div>
