RF Explorer WSUB1G PLUS battery up to 65% only

Some RF Explorer WSUB1G PLUS users reported a problem where the battery charge level seems to be limited to 60-65% only and apparently never gets above that level.

 

This has been confirmed to be a firmware bug, not a real battery problem. The initial battery charge level is calibrated by a factory procedure not correctly adjusted in firmware v3.03 and earlier. Nevertheless, the internal battery charge level is correctly adjusted by following the recommended initial charge process of 8hs, more details in the user manual (link) page 28 onwards. We recommend all users to follow this simple procedure to adjust calibration battery level. 

The RF Explorer WSUB1G PLUS firmware v3.05 and later corrects this problem and no longer display incorrect charge level, even if the battery was not calibrated. This firmware upgrade is recommended to all RF Explorer WSUB1G PLUS users. For more details please visit the download page (link)

Troubleshooting: Microsoft .NET

RF Explorer for Windows uses underlying Microsoft .NET 4.0.x technology, which is compatible with all Windows versions from WinXP to Win10. In most modern versions of Microsoft Windows, the .NET libraries are factory installed and automatically updated with Windows Update services.

 

Being a complex set of libraries, sometimes Microsoft .NET may have configuration, reliability or setup issues. If you run into issues like crashes where Windows OS or .NET libraries are reported as part of the crash, very likely the main cause is a faulty Microsoft .NET setup. Unfortunately RF Explorer for Windows cannot work reliably if there are issues in .NET.

 

Microsoft offer a few diagnostic and repair tools for .NET, please check below links to try to fix your system:

  1. Microsoft .NET Framework Repair Tool: link and link
  2. Microsoft .NET Framework Setup Verifier: link
  3. Microsoft .NET Framework Cleanup Tool: link

These are listed from less to more invasive, so you better try 1 first, and go to step 3 only if problem wasn't resolved.

We thank user Bob Buono for his help on background info to resolve .NET installation problems.

Troubleshooting: USB Drivers in Windows

RF Explorer connects to Computers and Tablets using a Mini-USB connector. For the USB connection to work, you need to a Silicon Labs CP2102 driver installed on your system. The driver is available for all Windows, Mac and Linux computers, and can be downloaded from this page. The Silicon Labs (also known as Silabs) drivers are high speed, high quality software produced and certified by Silicon Labs. Once the driver is installed, the RF Explorer for Windows software will automatically recognize and connect the device.

However, you may experience problems in some cases, such as the driver being not properly installed, or not being able to connect to the device even though the RF Explorer is physically connected and everything is apparently installed correctly.

In order to troubleshoot a connectivity problem, we suggest the following general steps:

  • Use a high quality USB cable. Some cables are not capable of sustain high current or have a low quality connector that may not give all the required power RF Explorer needs, particularly when charging the unit. Before you try anything else, make sure you test 2 or 3 different cables. This is the most common problems experienced and reported by users.
  • Some USB cables designed for cell phones include incompatible, internal resistors design to identify them as proprietary and will not work fine with RF Explorer or other USB devices. If you need a standard USB cable, please get one from our distributors or from any local or online shop. Just any normal, non proprietary Mini-USB connector cable will work with your RF Explorer device.
  • If you are using Windows 10 computer, and the USB driver is installed but RF Explorer device is not correctly detected, uninstall Silabs "Universal driver 10.x" and install drivers 6.7.x - even though Silabs advertise drivers 6.7 for Windows 8 and older, several customers reported this version working correctly in Windows 10 computers where <Universal driver 10.x> does not work.
  • Run the RF Explorer System Check tool, a free download to easily inspect configuration and common problems of your system: download link

RFESysCheck

If these previous steps failed, try next steps:

  • Uninstall all drivers and software from Silabs. Start from the control panel, remove everything listed as Silabs or Silicon Labs. After that, plug in the RF Explorer, and go to the Device Manager, and uninstall the Silabs COM driver that will show up there - probably with an exclamation yellow icon.
  • Reboot your computer. To check that all Silabs drivers were, in fact, uninstalled, go to the device manager again and, with RF Explorer connected, confirm it displays as "unknown device". If it shows up as a COM Silabs device, just uninstall that too, reboot and check again. If you are suggested by the OS to install any driver anytime, of course reject the offer.
  • You can easily check there are no old Silabs drivers left in your OS by looking for these two files. None of them should remain or exist. If they do, try again uninstalling the drivers manually from the Device Manager. Deleting these files manually from the File Explorer usually does not work because the OS protect driver files (so will be restored automatically from an internal cache).
c:\Windows\System32\Drivers\silabser.sys
  • Once your system is clean from old drivers, start with a clean setup of the latest Silabs drivers 6.7.x again. Check if it works now. If it doesn't, most likely your Windows or Hardware configuration is not really able to work with Silabs drivers. It is advisable to check if the problem persist regardless you having the RF Explorer power switch to ON and OFF, which demands different levels of current from the USB port. Some low profile Laptops may experience issues delivering the required current to the USB port. You can also try with no backlight enabled on the LCD as that reduce the current demand from the USB port.
  • If everything else fails, you may need to reinstall a clean, fresh Windows in your computer. The reason is the underlying drivers and other stuff may have a collision with what the Silabs driver is trying to do, and the only way to unlock bad state drivers is reinstall the OS.

Troubleshooting: USB Drivers in MacOS

RF Explorer connects to Computers and Tablets using a Mini-USB connector. For the USB connection to work, you need to a Silicon Labs CP210x driver installed on your system. The driver is available for all Windows, Mac and Linux computers, and can be downloaded from this page.

The Silicon Labs (or Silabs) drivers are high speed, high quality software produced and certified by Silicon Labs, and can be download and installed on MacOS X from this link.

You may experience problems in some cases, such as the driver being not properly installed, or not being able to connect to the device even though the RF Explorer is physically connected and everything is apparently installed correctly.

In order to troubleshoot a connectivity problem, we suggest the following general steps:

  • After installation of the driver or any other software, make sure to allow the software to run in System Preferences > Security & Privacy > General if you are using MacOS Sierra or newer (such as Mojave).
  • Use a high quality USB cable. Some cables are not capable of sustain high current or have a low quality connector that may not give all the required power RF Explorer needs, particularly when charging the unit. Before you try anything else, make sure you test 2 or 3 different cables. This is the most common problems experienced and reported by users.
  • Some USB cables designed for cell phones include incompatible, internal resistors design to identify them as proprietary and will not work fine with RF Explorer or other USB devices. If you need a standard USB cable, please get one from our distributors or from any local or online shop. Just any normal, non proprietary Mini-USB connector cable will work with your RF Explorer device (some proprietary cell-phone brands create non-compatible USB cables).
  • Check the internal device CONFIG MENU has the USB Bauds to 500Kbps (not 2400bps)
  • To check if it is correctly installed and the device being recognized, connect the device to USB port (no need to be in bootloader mode, any mode is ok for that). Then open a terminal window in your Mac, and run the following command:

ls   /dev/tty.SLAB*

if the device connected is being recognized by the Mac OS, then you should get a response in the terminal with a

/dev/tty.SLAB_USBtoUART

If you do not get this but a “no such file or directory” then try with a different USB cable and try reinstalling the drivers again.
