Thank you @mfalkvidd! I have been busy and had many issues to figure out for myself, but I still can't understand how binding with openHAB works. How does the information from nRF24 get to openHAB? I have MySensors Binding add-on installed in openHAB. I would be very grateful if someone could help with this last step. After this my first little sensor will be ready to go live.

First soldered device: And a small test:

any idea how often heartbeat messages would be sent?

@sineverba I see Thanks for clarifying.

Hi @GertSanders, Do you happen to still have the Eagle project files from version 3 you created and shared on OSH Park? I'd like to add a set of pads for the mini smd version of the NRF24L01. If not, I'll just use the version 2 files from openhardware.io and try my best to recreate the changes you made between them. Kind regards, AH

@pansen I have no oscilloscope near... Lets talk about it with Odroid community and hope someone could help me

UPDATE I think it's a problem with the arduino board itself. So since my previous posts I've tried multiple radios and I've got a 4 working nodes now: Mega + NRF24 UNO R3 + NRF24 DCcEle (clone) + NRF24 Nano DCCduino (clone) + NRF24 Plus the Raspberry Pi 2 as gateway with NRF24L01+ PA/LNA is working. So... it seems like it's a problem with that Uno board.... weird. I've tried multiple radios (specifically ones that worked on the other boards) and none of them work. Like I said before, the board and the Rp2 seem to be communication but not properly. Has anyone ran into a similar problem before?

@EddyG PCB received and tested, new version (v1.1) available here and on github.

Okay, finally got the original nrf24l01 SMD modules with the square chip visible... As exptected, things work just fine now, so the culprit of my issues was really the incompatible/fake "nrf24l01" SMD modules with the epoxy blob. If you want to use normal nrf24l01+ modules together with this smd gateway, DO NOT USE the smd module with the epoxy blob, as they won't work. Using only the fake SMD modules might work, too, but mixing the fake modules with real ones does not work.

@hek hi... sorry did not know this would be nice if you could do that... so people can get started with the new stuff !

@AWI thanks for pointing me to the doc it look great ! I will give it a try

Hello Guys , I am looking to run the rasp pi as gateway+controller with the nrf24 . Please where should i start from does it have any explanation like we have for the arduino s running mysensor ? .

@EasyIoT Can you share your implementation for MySensorsDriver?

Hi John, appLog.txt I also tried using datatype string but it doesen't work. Meanwhile I have studies the log files more detailed and found the following behavior: when defining the device skeletal and when updating the derived device (first approx. 25 lines in the log file V_STATUS is declared as string with values 51 resp. 52 as specified in the web interface. The entity is "Modul 433 MHz". Later on, when using the toggle switch in the web interface the value has changed in the decription in the log file (see line 164 or 185) value has been changed to on/off. With this definition it seem that the mysensors-Plugin is feeded has been changed from the specified values. My conclusion is that the change is taking place somewhere outside the mysensors-plugin. By the way, if I change the type to string do I have to use quotation marks in the web interface? Thanks a lot for your support. Martin

I faced similar issue and @TMRh20Projects replied in arduino forum. My issue was beacuse of cheap NRF modules chinese clones. After I replaced with good genuine ones, everything worked like a charm. Please check the NRF modules you are using. I wasted three days to figure out if there was some code issue, when at the end it was the NRF which created all the mess
