I think I did.
Could you test by making sure you add / have the following lines in your sketch:#define MY_RF69_IRQ_PIN D2 // GPIO 4 #define MY_RF69_IRQ_NUM D2 // GPIO 4 #define MY_RF69_SPI_CS D8 // GPIO 15It seems that the automatic definition of MY_RF69_IRQ_NUM was not working properly (I think on esp8266 platform it was supposed to be automatically defined as equal to MY_RF69_IRQ_PIN but I guess it was not the case)
Right now I have it working, both gateway and sensor compiled with MySensors 2.1.1.
I updated the default sketch, adding the missing line, and it's now available on github.
Let me know how it goes for you.

Currently I don't have a WeMos to test everything. I will come back to thins topic once I receive my WeMos from china. But you solution sounds good to me, as I did test the PCB with some other software and it was working without any problems. So it must be a problem related to the configuration and not to the wiring of the PCB itself.

Ok, this is a really stupid question but how do I use this with for example Domoticz? Do I still need to connect it to the usb-port or do I connect using MQTT or some other way?

Ok, I just soldered two of the shield using smd nrf-radios but I only got alot of errors from the serial monitor. Also the boards got hot as hell after a minute. The wemos was really hot and the nrf was untuchable.
I through that had done something wrong with the first shield so I soldered another but it was also as hot as the first.
And should I enter the SSID and password for my home wifi-network or should I use the sketch to create a new? I tried both with no success as I got some default network called aitinker or similar both times.
-
It should not get hot at all. The Wemos can get a few °C above room temperature but definitively not "hot as hell"
It happened to me once, when I had some solder joints between 2 pins of the NRF. You may want to test with a multimeter if, when the WeMos is unplugged, you have any shorts between adjacent pins.
A picture of the soldered board may help too.Best way is to edit the example sketch by adding your Wifi credentials on it before uploading them.

Hello, After soldering the radio and before connecting to power you should use a multimeter in "continuity" mode and make sure you have no contact between adjacent pins of the radio. I never connect a circuit using SMD nrf24 without having done this test.

Ok, I have tried several times now soldering/resoldreing the radio with same result. Continuity, that means direct contact? I get several hundreds of ohms between a few of the pads but it does not "beep" anywhere :)
Can something in my sketch cause this or is it 100% hardware issue?

You've got your answer here. You should have MOhms especially between Vcc and GND pins where I have infinite resistance.
-
another stupid question, do I need the capacitator on the radio-side for it to work?
-
It should indeed "beep" between all the pins.
NRF modules are also very fragile, once incorrectly plugged they are usually definitively toasted. So even if you desoldered and then resoldered them correctly it is unlikely they will work correctly.
Yes you need the capacitor radio side, it's the only required component, everything else is optional. It don't have to be 4.7µF, anything between 4.7 and 47µF will do, as stated in the assembly instructions.

I have got some strange issue when using RFM69HW. I modified the sketch by chosing RFM instead of NRF, and also uncommented the line "MY_IS_RMF69HW"
Everything looks like it is working when using the serial console, the wemos gets an ip and I can add it to domoticz. But after a couple of minutes it stops working. Same if I power it from mobile charger directly, works a while then dies. I have tried with different Wemos and it is the same. Can a faulty radio cause this or could it be something other? -
Not sure. I do not have any RFM sensors, I tested the gateway for a little more than a week with a mock sensor and it was working. Maybe some logs could help?
You can also hook up the RFM shield to a regular arduino nano to do a serial gateway, this way you can check if it's radio dependent or not.
-
Sometimes my own stupidity still amazes me. The pins of all my wemos where soldered at the oposite side as the ones in your examples. all the radios then got powered using 5v instead of 3.3v, not very suprising that the nrf radios got hot as h*ll and that nothing worked as it should.
Suprisingly the RFM69 seams to have survived. I guess the smd nrf24 all are toast.
Everything works perfekt now when I connected it correctly :)
-
Glad to see you have it working!
Let me know if something was unclear in the instructions or if it can be improved to prevent people to solder them flipped.
-
@Mynasru unfortunately the only other suitable pin would be D1, SCL.
Wemos do not have enough pins to do gateway + I2C, you will need to switch to a nodeMCU or similar.Also keep in mind that D2 is a MySensor default for ESP8266, I tried to have it moved when support was added https://github.com/mysensors/MySensors/issues/408#issuecomment-191403862 but without success, meaning you will need to reassign CE in your code.
