Thingy91 and buttons

[fmfernandez]

Hi! I'm using a Thingy91 and following the Nordic Academy course. The blinky example works fine, but when I try the second exercise, it seems like the buttons aren’t responding as expected. Since the Thingy91 has unique requirements, I’m compiling the code in VSCode and using nRF Connect to flash it. I’ve configured mcuboot according to the instructions on https://devzone.nordicsemi.com/guides/cellular-iot-guides/b/getting-started-cellular/posts/how-to-program-any-project-to-the-thingy-91-with-dfu and I’m uploading the app_signed.hex file. I’ve tried using button references from sw0 to sw3, but the output is always the same, no response.

Ok, so for development purposes, I really recommend that you stick to a DK when you want to go through these courses. Usually, it is possible to do much of the same things on the different Thingy boards, but it usually requires more knowledge, and it is easier to get stuck. 

So for the Thingy91, it is sw0, or button0 that is connected to the big button under the silicone lid. You can tell from ncs\nrf\boards\nordic\thingy91\thingy91_nrf9160_common.dts, where you can see that button0 is the one connected to P0.26 on line 21, and that sw0 is an alias for button0 on line 75. So from a software perspective, it is sw0 and button0, even though it is marked as SW3 on the PCB. 

No other buttons are defined, so I would expect it to give you some build errors if you were trying to use some other buttons than button0 or sw0. 

What board are you building for?

And what does the SWD switch, mentioned here:

https://docs.nordicsemi.com/bundle/ug_thingy91/page/UG/thingy91/hw_description/hw_figures.html

is in the nRF91 position. 

Are you able to successfully flash using the description found here?

Best regards,

Hi Edvin,

I’m building from the nRF9160, with the board target set to nrf9160dk_nrf9160_ns in the build configuration. The SWD switch is set to the Thingy91 position, and I’m able to flash it successfully using the Programmer app in nRF Connect. However, it seems the button isn’t responding as expected.

Thanks for your help,
