Module nRF24L01 and E28-2G4M27SX comparation

Projects Networking, Protocols, and Devices

I have built a board with E01-ML01DP5 module of Ebyte and another board with module E28-2G4M27SX

E01-ML01DP5 (20dBm) works with GFSK modulation; E28-2G4M27SX (27dBm) has LORA, FLRC and GFSK modulation

With same directive antenna, module E01-ML01DP5 at baud rate=250K, is better than module E28-2G4M27SX LORA (SF=8, BW1625) and better even when FLRC is used, with baud rate 0.5Mb. Now i will try with GFSK modulation.
I have tested in continuous rx tx loop at many distances.
So far E28-2G4M27SX has been a great delusion. Any comment?

Geht auch auf Deutsch?

I have moved your topic to the appropriate English language category of the forum @enzo1949.

In the future, please use the forum category appropriate to the language you are posting in. The International categories should be used if you are posting in the language to which they are dedicated, while the non-"international" categories should be used if you are posting in English. This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

You might get a better response if you explain all the acronyms and provide links to their datasheets.
But first read the pinned post re 'How to get the most from the forum'. That will among other things tell you how to post all the code and any needed Serial output as well as taking a photo of your hand drawn wiring diagram.

Thanks for advice, but when i posted, scrolling in top right, i did not find any indication. For me , international, was english.

Before going deep into details, i wanted to know if somenone ever used those modules.

The International > Deutsch category you selected should only be used when you wish to communicate in the German language. It is not appropriate to select when you are instead writing in the English language. In that case, you must use one of the English language forum categories.

In the future, please be more careful when you are selecting the category for forum topics you create. Keep in mind the possible confusion that might occur through browsing the forum with an automated translation feature enabled in your browser.

Your response is non-responsive.

What distances were you getting when you had clear line of sight between TX and RX ?

Hy.

I tested E28-2G4M27SX with LORA and FLRC modulation.

A PC is USB connected to one board equipped with E28-2G4M27SX, moving the other with another E28-2G4M27SX, at some distance.

I created an application in VBnet that actuated a continuous transmission from a unit and another, at baudrate of abut 100Kb/sec with LORa

and some more with FLRC.

In case of lost reception, a signal appeared.

Antenna was a flat square directive one; using module with integrated antenna is useless..

Distance tested, in open area but in populated environment, was 100m or some more.

I think that in open field the range is much greater.

What I have verified is that old module Ebyte E01-ML01DP5 performs better than E28-2G4M27SX.

Now i will test E28-2G4M27SX with GFSK modulation.

The hardware is proprietary.
