[SOLVED] Troubleshooting MQTT Gateway with Amplified NRF24L01+PA+LNA Long Range Antenna

So you mean USB > Nano > 5V Pin > 1117-3.3 Regulator > 3.3V for NRF24? Yes, that should work. The Nano passes 5V from the USB port more or less straight through to the 5V pin. Add some capacitors to the regulator, 10µF in and 10 - 100µF out electrolytic or tantalum should be fine to ensure its stability.

@BearWithBeard awesome thanks again for your help!

@BearWithBeard I found my problem. It turns out my arduino had a false contact on one of the ground pins I was using to power my radio. When I noticed, I resoldered the header pin on the nano and it magically started working. It works with both the normal and the long range antenna and I do see a big difference in range. Thanks for all the help again. Guess I will have some spare radios now...

Just got the modules but neither of them worked as a drop-in. Did you by any chance have to do anything different with these CD-Byte modules? I like that they are smaller and do look like the craftsmanship is a bit better. Was waiting for it to print out a case for it but I guess I am back to the drawing board. In the meantime, the older amplified modules are working great.

heck the pinout?
I got these, https://amzn.to/380eBob "nRF24L01 SPI PA LNA 2.4GHz rf Module E01-ML01DP5 2.5km iot 2.4 ghz rf Transmitter Receiver with Shield for arduino nRF24L01P". The pinout does look identical. I haven't had a chance to plug the gateway into monitor to see what the logs are saying just yet.

@fifo Those are good modules, I have some here. But you must use a capacitor on the power to them. Have you done this?
@skywatch after many nights of tshooting I found that my power brick was the one causing the issues. Not sure why it worked with old radio and not this one. It didn't cross my mind because it was a Samsung brand name 2000ma power brick and it was working properly, but last night it completely failed even with the old radio. I had no lights on my arduino or my ethernet module. I figured it was a good time to retest and the second I put it online with the new adapter it worked. Just wishing I would have tried that earlier...

@fifo Well done! - probably the new module needed a little extra power and the power brick was already failing so this pushed it over the edge. Failing psu can be difficult to diagnose until they fail completely, especially if encapsulated.
Power supply and cabling are usual suspects in this type of work.
Well done and good luck with the rest of the project!
