We have identified 3 requirements for an Android device to support USB Host Mode and be able to communicate with an RF Explorer handheld spectrum analyzer:
[1] The Android device must be running version 4.1 (Jelly Bean) of the OS, or higher.
[2] The output power on the Android device's USB port should be 5V.
[3] The configuration file android.hardware.usb.host.xml must exist on the Android device in the folder /system/etc/permissions. The presence of this configuration file is what enables USB Host Mode on your Android device.
If you have an RF Explorer device and OTG cable then this app can be used to confirm whether your Android device meets the requirements above.
If you do not have an OTG cable and your Android device uses a micro-USB port, then we recommend this OTG cable from Lindy.com:
