Twiddler

Isolate where the issue resides. Connect the Twiddler to another host (PC, Tablet, Phone, etc…) and see if the issue occurs on the new host. If it does, the issue resides in the Twiddler. If it doesn't, the issue resides in the host.

1. Problem: Bluetooth performance low.
   Solution: RF performance is not guaranteed due to the variability of RF interference in each user's environment. Also, the performance of Bluetooth radios and antennas of host systems are also variable. If you are noticing a degradation of the Bluetooth performance try the following:
   • Charge the battery of the Twiddler.
   • Move to a known “clean” RF environment and see if that solves the issue.
   • Try an external Bluetooth module if your host has an internal Bluetooth Module.
   • Get closer to the Host's Bluetooth Radio.

1. Problem: You can see the Twiddler in the Bluetooth Neighborhood but will not pair.
   Solution: Reset Twiddler's Bluetooth pair table by typing T14F1R. You will need to re-pair the Twiddler with any other device you have paired with in the past.
   
   
2. Problem: Twiddler does not pair with your host and does not even show up in the host's Bluetooth Neighborhood .
   Solution: The host does not support BLE 4.2. Install a Bluetooth device that supports BLE 4.2 like the LM506. https://www.tekgear.com/lm506.html
   
   

1. Problem: USB Drive does not mount.
   Solution 1 : Replace the USB cable. Most of the time, it is a cable issue. Either data or power is not flowing through the cable and is causing the error. If plugged in to a USB port, it just means power is flowing. It could be the data lines in the cable are not present or have been compromised.
   Solution 3 : Try a new USB Port that is known to work. Some systems have locked down USB ports or ports that are broken so plugging in to them will not work. Also, by changing ports, the OS will go through the enumeration process for the Twiddler USB Drive again and reload the driver.
   Solution 4 : Try a new computer. Sometimes it is a computer issue. Security settings set too high, Anti-virus getting in the way, or a hardware malfunction, trying a new computer may help to confirm the issue.
   

1. Problem: USB Drive mounts but is inaccessible.
   Solution 1 : Reformat the USB Drive. Format in FAT with an allocation unit size of 512. (The standard settings for FAT Formatting)
