Oh! I missed that. I will look for another one with cap.

@gohan
According to this site, the ebay-modules have also caps included. There are also some sellers providing according schematics.
I myselfe use a couple of them (also with +pa+nla-modules) and never ran into bigger trouble.

Anyone with different experiences?

Dear rejoe2!

Thank You for the infos.
Than i will buy two of this ebay version.

Best regards,
T

I probably missed that because I never seen the caps being specified

If they work, good find

@gohan

On ebay, i cant find the bypass capacitor in the specs. I have written to a seller asked about it. I will report to you about the answer.

I have tried once again the two high power nrf24 pa+lna (I put foil onto these) but these dont work. I think these are broken or very very bad ones.

Could you suggest to me a seller who sells High power nrf24 which ones you have got good experinces?

Thanks,
T

@Tommas
The caps are small SMD parts, explicitely mentioned you may find them on ebay here. (This is a 10PIN-Version, but as you see, despite the number of PINs, it's similar to the 8-PIN version you find everywhere.

But to be honest: I never saw the necessity to make measurements on this topic...

Hi rejoe2!

What kind of nrf24 do you use, and where did you buy these?
I think that you use capacitor as well, and stable 3.3V dont you?
Do you think that this shield is good for my node? It would be very good if i didnt have to use cables for nrf24....

Get some easy pcb instead or other similar solution 😀

@Tommas
I use nRF-Modules in the "normal" format and several pa+nla-Variants,. The first ones I probably bought from the ebay source mentionned on the mysensors-site (build-page), but by now, I may have used parts from around 4-5 different ebay-sellers as source. They look different, but until now, I only got "non-blob"-modules which all seemed to work reliably in the end. One time, I really was convinced to have bought fake and bad ones, but in the end it turned out these problems where mainly sw-related.

For powering, I initially used AMS1117-only-Modules and additional caps, but using the above adaptor-modules made things much easier, as they have all relevant parts on-board (3.3V+caps, space is no problem in my personal use-cases).

Fyi: As I now prefer wires over rf, I'm about to replace most of my nodes by RS485-variants.

@rejoe2

Thanks for the suggestions.
Had you got problems with nrf24?
Tomorrow i will try to configure openhab. I have tried to find a quick up to date guide for openhab 2 + mqtt mysensors but font find one.
Mysensors said that their bindigs support only ethernet or serial gateway officially.
I dont understand what is the diff (or why mqtt used mostly) the ethernet and mqtt solution but i have started the mqtt already.

Best regards

@Tommas
I indeed had some troubles with nRF nodes, but related to this.
FHEM is used as a controller and two serial GW's, so: no experience with the MQTT stuff.

[Tommas]

@rejoe2

I see. I hope, i can use it for a while:).
I think im closed this topic. The solution was to change the nrf24 modules, because i could not pair them.
The anoother problem was that i use two power source, and i didnt common the GND.

Thank you everyone who helped to me!

Reading through your posts: am I right in assuming that these NRF24L01 are rubbish and I should buy some proper ones with a chip instead of a blob?

Or has anybody a pair of them up and running?

Thanks and best regards,
Joachim

@trasrik

I havent had got blob one yet so i havent got experience with it. But i red about the blob version and it should work....
But I suggest to you that you should buy these from reliable brand/shop. I think Itead or keyestudio are reliable brands. And i bought a pair nrf24 from ebyte, but it hasnt arrived yet.

[gohan]

Yes, those are rubbish. I lost countless hours trying to get them working but without success

Ok, spent half the day trying to figure out what I was doing wrong and all I had to do was read the forum. The radios I purchase were junk. Not one of the 10 worked. Had everything placed on a board figured my workmanship was a little off or something. The radio was last to be checked.
WOOOOOOWWWWO

Thanks Everyone this post saved me a lot more time.
