Barometer readings incorrect after sleep

Hi Wio team, I've encountered a problem with the BMP180 Barometer grove. I can make it work on the Wio using the BMP085 firmware, but when the Wio wakes after a sleep, the values from the barometer are completely random. Any suggestions on how to fix this? Is there some way I can "reset" the baromet...

Re: ULB Recipes

Thanks sheepjms, I really appreciate the response and browsing through your project made some sense (although it didn't really address the ULB as far as I could tell). Mind you, I'm a Java guy, so I don't even have a C++ development environment. I'm simply coding the ULB in text only, taking extreme...

ULB Recipes

I'm starting a new topic specifically on the ULB here. Xuguang.shao has already provided some very valuable information in another thread, but I think ULB is so powerful that it would be nice to have a thread that shows some specific fully working recipes. I find that all the examples provided so fa...

nice work

what will be the cost ???

I have no 3D printer :(
Your best option would be to use one of the many services companies that do 3D printing on demand. I really have no idea how much that would cost, but if you pick someone local I can't imagine it being very expensive.

Wio board holder

As I was experimenting with the Wio board, I constantly feared that one of the Grooves may come into contact with metal pieces on my work desk. There was just so many short cables and small boards "flopping" all over the place. So I made a board that can hold the Wio and all the Grooves neatly in pl...

Re: How to get events from accelerometer

Hi xuguang.shao, thanks for that - that was very informative. I think using the ULB method may be the answer to all my problems :) The documentation is fairly clear, but I was wondering if you could help me with one thing: Where do I find the names and parameters for functions of the installed groov...

Re: How to get events from accelerometer

I'm hoping the Wio team reads these messages and respond. Since they already have events working for buttons and magnetic proximity, i'm sure it will be fairly easy for them to add events for other things. Using events over polling is sure to make a huge difference in the way we use the Wio plugins....

Re: Negative event option

Sure - I can detect that a button is released by doing a GET against the button. But what I need is an event (WebSockets) that fires once when the button is pressed and once when the button is released. In general it is far more useful and efficient to get events rather than polling. This goes for p...

Re: How to get events from accelerometer

Yes, it is plugged into the I2C and I can get measurements from it using GET requests. But polling it all the time doesn't work for me, I'd rather receive an event.
