Slow reaction time using Arudino Pro Mini with NRF24L01 Transceivers

[srnet]

My guess is that the Arduino Pro Mini is the problem since the Arduino UNO I used before worked fine but I am not sure why the Arduino Pro Mini would act differently if it a 5 volt input (same as Arduino UNO).

Well, the UNO and Pro Mini are the same processor, appart from the UNO not having pins A6 and A7 connected, so the code will be the same.

Which suggests you have some sort of wiring error or have them wired up differently ?

Where are you getting the 3.3V supplies for the NRF24 devices from ?

Simple nRF24L01+ 2.4GHz transceiver demo

Introduction The nRF24L01+ 2.4GHz transceiver modules are cheap and very effective but I have come across a few Threads in which people were having trouble with them so I thought it might be useful to gather together in one place a basic step-by-step sequence for getting them to work. EDIT 03 Feb 2021 - For this Tutorial install Version 1.1.7 of the RF24 library (available with the Arduino Library Manager). More information in Reply #30. Edit 29 Aug 2016. I have today downloaded and successfu…

Note in particular the power supply requirements.
