Dear gohan!

I have tried but nothing change. I bought two nrf24 from keyestudio without pa/lna , if it arrives i will try those.
I will write the experiences with the new ones.

Best regards
T

gohan

Are you using the PA lna? If so try a bigger cap, set pa power to min and you could also wrap the radio module with plastic and aluminum foil for shielding

Tommas

@gohan

Hi gohan!

Oh, OK! Im trying today. How can i set the power to minimum?

Have a Good day!

gohan

Look at the examples of other sketches, it's a define to be added, or you can set the default value in myconfig.h inside the library folder (look for the nrf24 section in the file)

ben999

Did you define the node_Id and parent_ID in the sketch ?

Tommas

@ben999

Hi Ben!

I havent define the parent ID because i havent known that i should do. i will try these settings as soon as i can.

I have already defined the node id in the node sketch

Thank you!

Hi Ben!

How can i define the parent id on the gateway?

Thanks
T

gohan

You don't have to define a parent ID in your case.

Hi Guys,
i have the same Problem
I've build a Serial-Gateway (Arduino Nano clone + nrf24) and a node (Arduino Nano clone + DHT22 + nrf24)
I do the connecition from this Site and added a 10µF capacitor to VCC and GND.
I try to set a fix Node-ID, but there is the same problem
This is the Log from the Gateway:

0;255;3;0;9;MCO:BGN:INIT GW,CP=RNNGA--,VER=2.1.1
0;255;3;0;9;TSM:INIT
0;255;3;0;9;TSF:WUR:MS=0

I think the node is send some data but the gateway not answer.
I increase the distance between the gateway and the node, but still the same problem.
Sorry for my bad english :blush:

gohan

do you see any message in the GW log when node is trying to connect? Because if not it may be a problem ot the radio module of the note not sending correctly, one of the radio modules could be a fake module and very poor quality. In the beginning I bought some modules that had a blob instead of an IC on the module and they were all not working. I can suggest to try some sample sketches to check if modules are communicating and also you could give a try to mysensors library from development branch

Jan Hilbrandt

No that is the full log from the GW. Damn...all my radiomodules have this blob like this one on the left picture.
I have also tested other NRF receivers (with the blob)

gohan

Those are the kind that normally doesn't work. Return them if you can or you can just dump them and get the good ones (look at the threads about genuine NRF24)

Tommas

@gohan

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?

gohan

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

Tommas

@gohan

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

@gohan

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
