Hello again,

I am unfortunately not familiar with Platformio either, as this is not a Nordic product nor something we support.
Looking at the attached code it seems to me that your call to bmp.begin() fails, and so you should check with Platformio which drivers it is using behind the scenes, to determine why it is unable to find the sensor.
Which input parameters should the begin function be called with?
From your commented out line of code it seems that you should provide the device address to the begin call, while you do not in the failing function call. I cant see that you are providing this address elsewhere either.
Is this the exact code that worked on the Arduino, or did you change anything in-between?

Could you also detail your connection between the sensor and the nRF device, and confirm that you have checked the nRF module's datasheet to see if the pins you are attempting to use are available?

Best regards,
Karl

I'm using Platformio in VScode so the code is the exact same. The board is an nRF52-DK (PCA10040) using SDK 17.1, or a customized board with the nRF52832. I don't have any errors from the code, the problem is that it doesn't detect the pressure sensors.

Hello,

[quote user=""]

In Arduino IDE using Arduino UNO it woks.

In VScode with the nRF52-DK, the Terminal will show "Could not find a valid BMP280 sensor, check wiring or "
"try a different address!"

I am not familiar with the Arduino UNO or how this can be done in Arudino, unfortunately. Could you show me how you attempted to do this in VScode for the nRF52-DK?
Could you also clarify if you are using the nRF5 SDK, or the NCS SDK? Which version are you working with?
Did you get any errors from the nRF52-DK? If so, what did they read?

Best regards,
Karl
