AI Thread Summary
The nRF24LU1P facilitates wireless communication through its MultiCeiver™ feature, allowing a primary receiver (PRX) to manage six unique data pipes on a single frequency channel. Each data pipe operates with its own address and can be configured for distinct behaviors, enabling communication with multiple transmitters (PTX). All data pipes share common settings, including CRC configuration and air data rate, but must have unique addresses to avoid conflicts. The discussion highlights the importance of configuring data pipe addresses correctly to establish a robust network of radios. Understanding these communication pipelines is crucial for effective wireless link development using the nRF24LU1P.

Hi, has anyone had any experience developing a wireless link using nRF24LU1P? I have hard time understanding what are different communication pipelines. Are we switching between different frequencies when we switch from one to another?
Thank you.

No. All pipes are on the same active channel.

The manufacturers data sheet is here.
https://www.nordicsemi.com/eng/content/download/2723/34042/file/nRF24LU1P_O_Product_Spec_v1.0.pdf

Extract from data sheet said:
6.4.8 MultiCeiver™
MultiCeiver™ is a feature used in RX mode that contains a set of six parallel data pipes with unique
addresses. A data pipe is a logical channel in the physical RF channel. Each data pipe has its own physical
address (data pipe address) decoding in the RF Transceiver.

The RF Transceiver configured as PRX (primary receiver) can receive data addressed to six different data
pipes in one frequency channel as shown in Figure 13. Each data pipe has its own unique address and can
be configured for individual behavior.
Up to six RF Transceivers configured as PTX can communicate with one RF Transceiver configured as
PRX. All data pipe addresses are searched for simultaneously. Only one data pipe can receive a packet at
a time. All data pipes can perform Enhanced ShockBurst™ functionality.

The following settings are common to all data pipes:
• CRC enabled/disabled (CRC always enabled when Enhanced ShockBurst™ is enabled)
• CRC encoding scheme
• RX address width
• Frequency channel
• Air data rate
• LNA gain

The data pipes are enabled with the bits in the EN_RXADDR register. By default only data pipe 0 and 1 are
enabled. Each data pipe address is configured in the RX_ADDR_PX registers.
Note: Always ensure that none of the data pipes have the same address.
Each pipe can have up to a 5 byte configurable address. Data pipe 0 has a unique 5 byte address. Data
pipes 1-5 share the four most significant address bytes. The LSByte must be unique for all six pipes.
 
I missed it on the datasheet. I guess data pipes help to create a large network of radios. If I understand right two different data pipes each could have one radio with identical addresses?
Thank you
 
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
