NRF24L01+ MULTI TRANSMIT 1Tx multiple Rx

Hi,

I have a Question regarding one project in which 1 NRF24L01+ Module transmit to multiple devices at the same time ? How we can configure for multi transmit ? like Tranmitting GPS Data to Clocks wirelessly. I have read about MultiCeiver and how it works. But what if i want to transmit single signal to multiple NRF24L01+ Receivers ? means 1 Tx and other 5-10 Rx NRF24L01+. is it possible ? how can we do that with NRF24L01+.

thanks..

  • To broadcast a payload/package with the nRF24L01+ you should either disable enhanced shockburst/auto-ACK or use the no-ACK flag. You basically would have to give up the built in ACK support and instead handle this in your application if needed. You only need to prevent the multiple PRXs from sending ACK at the same time. You also need to configure the PRX to use the same address to receive the broadcast from the PTX.
