nrf24 range issues
-
I'm not sure which is better: this or the Ebyte ones. They seem about the same to me, but I haven't done a rigorous comparison. Anyone else compared them?
I agree that the limited range of the regular, non-amplified modules, can be quite a frustration! If anything, maybe beginners should start with these and then perhaps later dial it back if so inclined for energy savings or the like.

Resolved !
I finally ordered 2 of these (https://www.aliexpress.com/item/2PC-Lot-E01-ML01DP5-nRF24L01-PA-LNA-Long-Range-2-4GHz-RF-Wireless-Transceiver-Original/32797433295.html?spm=a2g0s.9042311.0.0.wuTpjZ) . Thanks @Nca78 for recommending them earlier.
I plugged them on my base modules and did my usual test.
The range is now way beyond my needs! I have 100m+ of range (I was too lazy to take the boat to cross the river at the bottom of my property..)I'm a bit bitter to have wasted so much time but very relieved too. I have the feeling that radio will not be an issue anymore (and so I'll save hours of troubleshooting)
I've got a few conclusions:
_ It's good to ask help: thanks @Nca78 and @Yveaux !
_ As mentioned earlier in the topic with @Yveaux I think the modules recommended on the mysensors websites should be changed to these ones (or at least others that have been tested and work). Yes they are more expensive (3.4€ in my case) but it's still cheap and definitely worth the saved dozens of hours trying to figure out the radio issues. I'm also sure it would help not losing new users that get too frustrated
_ I think the whole set of tips/tricks to improve the range of some modules (solder, capacitors, clean power source, base module...) can be a bit of a trap. I don't deny that it can help marginally or drastically on some modules. But my experience has proven that even with all of these tricks applied it still would not make it with some modules. Even with modules advertised as "long range". As @Nca78 said it in is very first post, if we know that some modules just work "out of the box" we should stop recommending dodgy ones that can sometimes be fixed with tricks or not.If I have the motivation I may even try to remove the base modules (making sure I still provide 3.3v and not 5v) and will see if they're still needed with my new radio modules.
i m in same boat, i have order 3 of those as well. until i read your post i was about to give up on using wireless. thanks for reporting back and sharing your experience.

Just to contribute some experience, i had NRF24L01+PA+LNA on my wifi gateway, all my battery powered sensors (NRF24L01+) were communicating fine but my relay node wasn't communicating at all i tried different arduino (nano, mini) different combination of NRF24L01+ and NRF24L01+PA+LNA but no joy, i just change NRF24L01+PA+LNA radio of my gateway and now my battery powered temperature sensors and relay node can talk to gateway. my conclusion if one node isn't working it may not be that node is faulty. so node and gateway should get checked.
