Hi Christian, You reafly found the problem, perfekt! It was the "bigger letter setup" for my little phone, I'm to old for this small charakters :-). Thank you for good support! I think you could close this Item. Hi Werner, I am glad the problem is solved. I will try to fix this in the com...

Hello Werner, I use your "https://www.bylund-automotive.com/store/#!/products/lambda-wifi-bundle". The iphone 7 SW is now 15.1, but it's the same: greater 10V it shows "1...". Excellent, thank you for confirming. Did you have a email address for me? Please send the screenshot to ...

Hello Paulo,

You will find all you need in this post.

Good luck!

Hello Werner, The Lambda Shield App is capable of showing a much higher voltage, lets see if we can figure out what is wrong. It would be good to know if you are using the original Lambda Shield or Lambda Shield 2? Is it possible for you to email a screenshot of the Lambda Shield app when it is beha...

It appears it was an issue with the additions to the code I made I went back uploaded the original gui code again and it appears to run fine and is working on all 3 unos. Great you found the problem. Check your code for memory use and access of shared peripheral, this is typically the cause for cra...

Hello.

Could you please share a picture of your setup to see what is connected where, you mention that you have a display connected for example. Does the GUI code work without anything but the shield connected?

Thank you.

Hi Fabio, With the NOx shield is it possible to measure the two variables by Arduino? both Nox and O2 ? Yes it can measure both O2 as the Lambda Shield but also NOx for lean gases with excess of oxygen. Do you have a CO (carbon monoxide) measurement shield? Sorry, no. I already have a shield for mea...

Glad you got it working.

There is some information about this in the Troubleshooting Section. Under point 5.

Thank you for your suggestions Chris!

Hi Tomaso,

I think trying to use any MKR board with a UNO-style shield is possible but not feasible.

Regarding I2C displays. For UNO boards you can solder the cables directly to the shield. On Arduino Mega you can use the extra I2C pins.
