Hello,

we are currently piloting a study within our team (Study ID 937) and I noticed that for everyone using an iPhone, the bluetooth data are missing. I also know from at least one participant (ID: 40392), that they do not see the option to endable Bluetooth data collection in the app.

However, on my android device, everything is working just fine.

Is there anything I might have specified wrong are could this be an issue with iOS?

Best  
Sarah

Hi @sarah.kritzler

As it’s explained in [our documentation](https://learn.ethicadata.com/documentation/data-sources/contact-network/#bluetooth), Bluetooth data source is not supported in iOS devices.

Thanks
