Troubleshooting

Hi @soso. Warm welcome to the MySensors community! MySensors is a fantastic project, but it might not be the right project for you. MySensors takes care of communication between sensors, and from sensors to a gateway which in turn connects to a Home Automation Controller. To me, it sounds you don't need any of that. The RFduino can use bluetooth to communicate directly with an iOS device. No need to communicate between sensors, no need for a gateway and no need for a Home Automation Controller. You might be better off asking in the rfduino forum. With that said, there might be some rfduino users who also use MySensors so hopefully someone is able to give some recommendations. If you want to read more about what can be done with MySensors, take a look at the getting started guide.

Thank you Martin, that solved my issue!!

@Newzwaver Great, glad it's working again!

I have this one, looks the same... [image: 1457097850598-upload-506933d0-e884-43a3-868d-57bfdad86b69]

@Matt-Pitts For the mqtt client on the dev branch there is a sticky guide in the forum: http://forum.mysensors.org/topic/2352/guide-setting-up-and-testing-mqtt-client-gateway For the message types etc see the serial API. It's my number one visited page on the mysensors web. Although I'm starting to know it by heart now.:wink: http://www.mysensors.org/download/serial_api_15

The same issue here! I got a 'nice' FTDI adapter with 5v <-> 3.3v switch.... After experiencing the same, i noticed that the switch on the adapter is bogus and it always outputs 5v... :astonished:

@SiLeX So it may be due to an incorrect connection? Pins of module are untagged and I connected them according to the positions of schemes that I found online. All modules have same pinout?

It must be something very dumb. Check that you have a solid galvanic connection to nrf modules on all lines.

I found the error.. it was a damaged NRF24L01+ Module..

@mfalkvidd said: in MyConfig.h you should be able to define it in your sketch before #include <MySensor.h> Overriding defines from sketch only work in the development branch. It requires a source code inclusion "hack" that's not in place for 1.5.x.

@8art-5imson said: i am trying to compile the ethernet gateway and when i first started was getting loads of "directory dosent exist" errors i fixed this by moving the mysensors library. following the IDE install instructions on the site the IDE installs to C:\Program Files (x86)\Arduino\arduino.exe (the Default). but the sketches folder where i put the my sensors library is in C:\Users\Chris\Documents\Arduino\libraries i have copied the libraries folder to both locations and have got past all the doesnt exist errors. but now i get the following compile error: C:\Users\Chris\Documents\Arduino\ethGateway\ethGateway.ino: In function 'void output(const char*, ...)': ethGateway:135: error: 'serialBuffer' was not declared in this scope vsnprintf_P(serialBuffer, MAX_SEND_LENGTH, fmt, args); exit status 1 'serialBuffer' was not declared in this scope i have removed and re installed the arduino IDE and mysensors library several times but i get the same error every time ! i think it could be somthing to do with the directories been in the wrong place and duplicated all over. could someone please clarify the best place to put arduino IDE, The Libraries and the Sketches folder. or point me in right direction to get rid of this error. i have edited the config file to enable soft SPI. many thanks Chris Just figured it out .The gatewayutil.h file i was using was wrong, i copied and pasted the version off the codebender sketch (which is completely different to the one i had, dont know where it came from ??) but noticed line 25.....char serialBuffer[MAX_SEND_LENGTH]; sorted

well, i've got lost with this git thingie. i'll just edit the channel inside myconfig.h with the correct channel everytime i upload a sketch according to the gateway it will connect to. thanks a lot anyway

@Tias Right, I gave up and got an Arduino Nano to use as a Serial gateway instead. It's initializing ok and entering the loop() but presents other issues, however, that's for another thread. Cheers & thanks ! /T

Thank you! @chrille !! Much appreciated.

I'm now using W5100 Ethernet, this is what I have on startup: 0;255;3;0;9;Starting gateway (R-NGA-, 2.0.0-beta) 0;255;3;0;9;Init complete, id=0, parent=0, distance=0 0;255;3;0;9;Attempting MQTT connection... 0;255;3;0;9;MQTT connected With the following request I was able control my 1st relay: mygateway1-in/0/1/1/0/2 , value is either 0 or 1 Seems to be working!

@vlad I am having the same issue. Where did you change keepalive timeout to a long time? Essentially, what file did you edit, what parameter and to how long?

But gw.begin(NULL, 1); worked now. Thank you! Might be worth to write this somewhere in the guide.

It's strange ! Can you post a picture of your sensor and gateway ? Have you try with a second nano ? It's not normal to have nothing on the serial monitor when using USB. One thing you can do it's to connect a LED to any digital pin and switch it on at the end of the init() function ?? David.

It is working now. If I have to send the value as a string and not int will it work if i send string values of temperature where it should be a int ? That will be my next test :) @BartE thank you very much for the help.
