EMDK likely doesn't offer functionalities for network tethering as it focuses on scanner operations.

Programmatically enabling tethering requires elevated permissions that are generally not available to apps. This is a security measure to prevent unintended network changes.

Hi Fran - Zebra devices do support Bluetooth tethering, but it is not controllable programmatically. 

Zebra Mobility Extensions (MX) offers the ability to control thousands of Android features through EMDK, but unfortunately this feature is not among them at this time. 

However, there have been discussions recently about adding it, and I suggest contacting your Zebra account representative ASAP about submitting a feature request that describes your use case. Customer need is the primary driver behind Zebra engineering decisions.  

Thank you for using Zebra products.
