https://devzone.nordicsemi.com/f/nordic-q-a/64844/rf24-fully-connected-networkHi .thank u for reading this .First sorry for my english. This is the story: I try to make a flexible mesh using multi nrf24l01+ more than 10 nodes. I searched so many topic about this but i didn&#39;t find good solutions for my purpose.

You may also look into increase retransmit delay if you are using long ACK payloads. Is there any difference if you add a dummy random value to the payloads.</p><div style="clear:both;"></div>
