Another learning project based on this Nordic Semiconductor product, NRF24L01 chip. Nordic, RF, 2.4 GHz part with really flexible and high bandwidth radio performance for digital sensor data.
Purchased a 6 pack from Amazon for very little Dollars – maybe only $4 per circuit board and trying to set up. From the problem solving post from 5 years ago, here are some steps:
- Review prior projects – have we done this before?
- Look at Safari and Amazon for answers – are there books on this topic?
- Research physical books – look at the physical library
- Search internet – Arduino, Wikis, Specialist sites, then general search
- Search YouTube – find gurus and experts who have series, then individuals
Well, I hit gold with the 4th bullet, internet search where I landed on an Arduino wikispaces site that has a number of posts on the nRF24L01 chip, including a page on how to solve problems with the device.
Although I was keen to dual bypass the Nordic breakout board and connect it the the 3.3 VDC pin of the Arduino Pro Mini (3.3 V, 8 MHz), it turns out that this probably was the problem. I connected both devices to my lab supply of 3.3 VDC, and the test routines that I loaded worked immediately! First time!

Now on to integrating this with a sensor for remote data logging. Will be using BMP180 sensor to monitor pressure and temperature.
