This issue was not sensor-related.  There was a problem in the software used to show the measurement values after reading them from the HOSTOUTx registers.

Thank you for your help, and apologies for the false alarm.

Hi Gary,
Apologies for the delay.  The EFM8 is a Silicon Labs 8 bit processor.  Information about the processor can be found here:  https://www.silabs.com/mcu/8-bit/efm8-sleepy-bee/device.efm8sb10f8g-qfn20

The target MG1 processor is not connected to the EFM8, there are actually three Silicon Labs processors on that board and it is the non-target processor that runs the JLink to program the MG1 and the EFM8.  You can use our Simplicity Studio tools to program all of our processors:  https://www.silabs.com/products/development-tools/software/simplicity-studio

Thanks,

The error/bug is in gateway-relay-mqtt.c... in sdk_path\protocol\zigbee\app\framework\plugin-host\gateway-relay-mqtt folder.

I did a few changes... attached.

So Z3GatewayHost needs to be rebuilt.

You can also go into File Explorer, select all of the files you want to copy to the folder in the project and Drag and Drop them into the folder.

Once you do that you will be prompted with a dialog box that allows you to select whether to link the files or copy them to the project.

But as @YK mentioned, you will lose the connection to the SDKs at that point and will have to manually make sure all projects are up to date.

You use the following steps to accomplish this.

1) Right click the linked file you want copied to the project directory.

2) Select the "Copy Linked File into Project" option. 

This will add the file to the project directory and change the status of the file from linked to being a part of the project.

Thanks,

The DA14531 is a 16 MHz M0+ core device so I am surprised you say you can use it at 32 MHz to clock the SPI.

On the EFR32BG22 you will need 48 MHz HFXO for the radio; that will make your system clock <= 48 MHz so your peripheral clock/2 will be 24 MHz, max.  Cannot get 32 MHz for SPI.

The BG22 does have a DPLL and a maximum system clock rate of 76.8 mHz, so you CAN get 32MHz SPI by setting the DPLL output to 64 MHz but that will chew significant power and you would only be able to do it whenever you are not communicating with the radio.  It would likely be problematic.
