Ebyte nRF24 module comparison (2020)
-
I have ordered a set of E01-ML01S and intend to test them against my gateway.
@orhanyor: I would definitely expect the E01-ML01S to do better than a couple of meters. That is the range of the shittiest noname nrf24 clones (when they work at all).

A lot of my NRF24 problems were solved when I used a sheet of metal for a groundplane on the +PA+LNA module I use on my gateway.
Will definitely try some Ebyte modules when its time to buy some more.

@sola they can do the job depending on your environment. in my experience if theres an obstacle like if your module is in a box if modules are not in line of sight pa lna solves the signal issues. otherwise those without pa are ok too. one fatal mistake is to put some metal or lean the antenna back against a ground plane. oh man that totally kills the signal :) its a newbie mistake but its worth mentioning.

@orhanyor A piece of aluminium fixed my problem (Well 99% better). The sensors I have report in every 2 minutes and I get an error alert if they do not. Without the sheet in place it is just non stop communication errors. there is a thread I posted all about it.

thanks for this survey !:

Hello Sola
You might be interested to know I’ve developed a rather full featured RC system for model helicopters using the ML01DP5. It is proving extremely reliable even at great range. Today I’m testing with the ML01SP4 as it’s smaller - I hope the range is ok. There’s really only one way to find out ! Here’s a recent test …

@mmessiter Great stuff, congrats for the system.

I have built 2 nodes with E01-ML01S (the cheapest module) and I have pretty good experience with them so far.
I didn't have to use any capacitors to improve range, they are directly connected to some medium-quality Arduino Nano GND/3.3V.
One of them is a lighting controller node, ~3 meters from the PA/LNA gateway (+ a 30cm wall) on the same level as the gateway.
The other one is a repeter node and is ~10 meters from the gateway (+ a 20cm wall, same level as the gateway). In this case, radio orientation was important to get a good signal.
One of the test modules could communicate with the gateway through 2 walls and a the ceiling (steel-bar reinforced).
All-in-all, I am satisfied with the signal stability of these modules.
It is a bit finicky to solder the wires to the module because the pads are very small.
I always put some solder on the pads first and reheat when I attach the wires.
