It would be great to be able to do the same but from a MacBook, but Logitech didn't release such an app for macOS. I believe this should technically be feasible from any device with a Bluetooth 4 + LE device (which my MBP Retina, 13-inch, Mid 2014 has).
Would you know how this could be achieved, through a Bluetooth software or script?
What I found so far:
This is what my Mac shows for the UE in System Information > Bluetooth
UE MEGABOOM: Address: 88-C6-26-89-57-B3 Major Type: Audio Minor Type: Headphones Services: Headset, Wireless iAP, LWACP, Hands-Free unit Paired: Yes Configured: Yes Connected: No Manufacturer: Cambridge Silicon Radio (0x8, 0x307D) Firmware Version: 0xFFFF Vendor ID: 0x000A Product ID: 0xFFFF Class of Device: 0x04 0x06 0x240418 EDR Supported: Yes eSCO Supported: Yes SSP Supported: Yes
I've tried LightBlue but it can't show the available services for the UE:
