First:
I do not like the nRF24L01+ very much.
It has a very weird and illogical set of features (such as the 6 pipes) that are more of a nuisanse and hindrance to use it in a sensible way then an asset.
Then there is the "+" in the type number. Without the "+" it is a very much different chip with other (older) features.
There are also clones floating around Ali / Ebay / China, which do (often) work, but are arount 99.9% compatible.
The most used 8-pin breakout board for these chips do not have enough decoupling capacitance. Reliability and range can be improved by soldering more capacitance directly on the connector pins.
As of your Logic Analyser question:
first make sure you have proper ground connectons between all your (bread?) -boards, power supplies, and development / programming / and Logic Analyer boards.
Always connect the GND connections first between all applicable sub circuits.
15 cm long fly wires do not make a good GND connection.
15 cm long fly wires do not make a good GND connection.
If you then still experence data issues, it is time to get an oscilloscope and check the signal integrity.
Also agree with MarkF. From what I remember nRF24... works for 3V3, but not much under 3V. It does not have a very wide operating voltage range such as most uC's do.
A maybe related issue that I have encountered a few times, is that if you use a (small) single power supply for multiple boards, and you hot wire a new board in your setup, that the buffer capacitance on such a board can momentarily dip the powersupply below the operating voltage of the other boards it is connected to. Even if it's for only a ms, it is desastrous for any chip that has a flipflop in it.
