KNOWN TO BE WORKING
The KX3 Companion needs a USB Serial connection to use the Elecraft KX3 USB cable. This is accomplished thanks to something called “USB Hosting”. So all devices that support USB Hosting (Android 4.1+) should in theory work. Different device manufacturers release devices with custom Adnroid versions that may or may not support USB hosting. Also, in case of carrier branded devices, they also may disable this feature.
The following list is based on feedback from users and personal experience. Please help me completing the list with your personal experience and configuration by emailing me directly at “kx3companion AT gmail.com” or leaving a comment below. Thanks!
The list is based on “un-rooted” and “un-hacked” devices. So it should work ‘out of the box’:
- Google Nexus 7 2013
- Google Nexus 7 2012
- Samsung Galaxy Tab 2 7.0 (espressowifi)
- Samsung Galaxy Tab 3 7.0 (lt02wifi)
- Samsung Galaxy Tab 3 10.1 (santos10wifi)
- Samsung Galaxy Tab 3 10.1 (GT-N8013)
- Samsung Galaxy Tab 4 8.0
- Samsung Galaxy Tab 4 10.1
- Samsung Galaxy Note 10.1 2014 Wifi
- Samsung Galaxy Note II (t03g)
- Azpen A700 7″
- ASUS MeMO Pad 7 (ME176CX)
- Azpen A1023
- Google Nexus 5 (hammerhead)
- Samsung Galaxy Note 3
- Samsung Galaxy S2 (GT-I9100)
- Samsung Galaxy S3 (m0)
- Samsung Galaxy S4 (jflte)
- Samsung Galaxy S4 (jfltevzw)
- Samsung Galaxy S5 (kltevzw)
- Motorola Moto G
- Motorola Droid Maxx
- Motorola Droid 4
- Sony Xperia Pro
- OnePlus One
KNOWN NOT TO BE WORKING
These devices currently do not suppor USB Hosting.
Some devices are locked even if they technically can do USB Hosting. An example of this is all the Amazon Kindle tablets and some Sprint US carrier branded devices.
Sometimes it’s a matter of versions like for the Asus Memo Pad 7. Previous version ME173X doesn’t work, the latest version ME176CX works.
If you have a carrier branded device and the KX3 Companion FREE version doesn’t work, please ask to your carrier if they locked the USB Hosting. In some other cases it the OTG cable that is at fault.
The following is a list of known devices that have USB Hosting disabled:
- All Kindle Fire
- Samsung Galaxy Tab 3 7.0 (Model SM-T2100R)
- Samsung Galaxy Tab 4 7.9
- Asus Memo Pad 7 (ME173X)
- HP Slate 7 (model 2800)
- Some Sprint US branded devices
Again, please help me keeping this list updated with all the know to be working/not working devices based on your personal experience. And try to contact your manufacturer or carrier and ask if they will unlock USB hosting for you or in future versions. Asking never hurts.Thanks!
