U1177A (IR)-to-Bluetooth Adapter this designed to have connectivity with Bluetooth 4.0 Android phones.
When it comes to PC connectivity it is required one USB-Bluetooth module this also compatible to Bluetooth 4.0.
Unfortunately and even up to date, most to all USB-Bluetooth module they require software support by the operating system (windows) or by its one module manufacturer.
The Bluetooth driver stack in some modules requiring purchase of third party software, and in some other cases there is free Bluetooth driver stack at the size of 100MB.
Speaking of hardware selection, this is the tricky part.
Only if you buy and test such a PC USB-Bluetooth module you can verify compatibility with Agilent-Keysight PC software logger.
Basically such hardware suggestions/recommendations they should come from Agilent-Keysight, (IR)-to-Bluetooth Adapter it is their product, and what they did was to skip research of recommended solutions for wireless connectivity with windows PC.
Therefore feel free to add in this topic any solutions of PC USB-Bluetooth module and of Bluetooth driver stack , which both worked for you.
All Agilent-Keysight Android APP has stopped be developed, significant issues are not getting fixed, practically Android APP they are limited in usage tools.
Therefore wireless PC connectivity with compatible modules this is an area to be rediscovered regarding solutions by us the end users.
Personally I did have good success by using instead Serial - Bluetooth module, but this is not the most cost effective solution. http://www.ittsb.eu/forum/index.php?topic=1159.0
