Oh ok. Thanks.

I tried to attach 100uF capacitor but the results are same.(no reply) . The node ID is defined, the parent ID isnt.
It seems that im out of ideas. I wait for the new nrf24 without pa lna.
Im attaching some pictures about the project.
Should i foil the nrf24 modul?

I can't see the link but I trying to foil the radio module could be an idea, as I wrote a few posts earlier

Dear gohan!

Sorry, it is a private home server and it was in maintenance mode when you were trying to connect. Now it should be working.
(The new nrf24 have just arrived so im going to try these as soon as i can)

Best regards

Dear Gohan!

I have just tried the new nrf24 standard, and it works!
It seems that the GND should be common (im newbie).
I would like to test further with the pa+lna version, but....
I have an other question.
I would like to power the board with 5V from the power module 5V output, and i would like to program the board via USB at the same time. How should i connect the power module to the board?

[gohan]

why do you want to do that? And yes, GND is normally common

[Tommas]

@gohan

Dear Gohan!
Everyone suggests that if you use pa+lna version you should power it from external regulated 3.3 V because the arduino clones 3.3V isnt strong enough. So i bought externaI power source.... i have figured out today that i can common the power source's gnd with the arduino gnd. It is working....

What is last that i would like to power the arduino uno from power module 5V and connect it to my computer same time... i dont know how to do it.

I have tested the two nrf24 pa+lna and these arent working together only. Separately is OK.

I will go with the standard nrf24 , make it working than i will try to buy branded nrf24 pa+lna.
Have you got favourite brand for cheaper electronic parts?

[gohan]

Not really an external power source, you can just use the 5V output from the arduino and use a voltage regulator to 3.3v.
I bought some of these http://www.gearbest.com/transmitters-receivers-module/pp_453011.html and I am very happy as they allow for quick swap of the radio and already have caps

@gohan

Dear gohan!

Thank you for your help. I will buy from ebay this one: https://www.ebay.com/itm/200960749614

And im planning that i will buy a shielded nrf24 pa+lna .
Today im installing an openhab and try to transfer the datas from gateway to the openhab...

What projects have you done already?

Best regards

[gohan]

The one on ebay it's missing the capacitor so remember to add one on the radio

[Tommas]

@gohan

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

[rejoe2]

@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?

[Tommas]

@rejoe2

Dear rejoe2!

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

Best regards,
T

[gohan]

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

If they work, good find

[Tommas]

@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

[rejoe2]

@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...

[Tommas]

@rejoe2

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 😀

[rejoe2]

@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.
