Hello! Does anyone experienced fail to find lms22hh sensor when loading examples from avnet in Microsoft Visual Studio?

Question

After hours of installing/uninstalling Visual Studio 2017, Azure Sphere SDK, creating Azure acount and tenant,last night a managed to load the example from Avnet first part tutorial. But in the output window it shows me that it failed to find the lms22hh sensor. It found one sensor on the i2c.

Does anyone know if i have to decomment some instruction or change some jumper or is a problem with the board? Has anyone experienced this? I find the usage and developement on this board very challenging and slow going due to endless documentation provided both by avnet and microsoft!

We've seen examples where access to the slave I2C LPS22HH device fails. Usually a power cycle of the board will clear the issue.

Regarding the temperature sensors showing different readings. These temperature are internal to each silicon device (measuring core temperatures) and are measuring room temperatures.

I managed in the end, to get data from the sensor i solved by making the example 1 from avnet closelly and trying different settings in Visual Studio. There is no problem with the example although i think that the two temperature sensors must be calibrated... they show me two values different by just 2 degrees... i have to dig deeper in the code to see if that is correct!

I have a typo in my message above, and I can't edit it. So here's the correction . . .

These temperature are internal to each silicon device (measuring core/die temperatures) and are NOT measuring room temperatures.
