 =====Troubleshooting=====
-====Power====
+====First Steps====
-  - **Problem**: Twiddler is non-responsive \\ **Solution 1**: Slide Power Switch on front of Twiddler to the Right. \\ **Solution 2**:  Battery is too low. Plug Twiddler into USB and charge the battery.  [[getting_started#powering_up_the_twiddler_for_the_first_time|LED will be red while charging, green when complete]].  - Problem: Twiddler's LED is a dim red when plugged into USB and goes bright red when buttons are pressed. \\ **Solution 3**:  Internal Battery has been dislodged.  Return for repair.
+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.

Plug Twiddler into USB and charge the battery. [[getting_started#powering_up_the_twiddler_for_the_first_time|LED will be red while charging, green when complete]]. \\ \\
 ====Bluetooth====
   - **Problem**: Bluetooth connection keeps resetting. \\ **Solution**: Battery level too low.  Plug into USB until LED turns Green. \\ \\
-  - **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.

-  - **Problem**: You can see the Twiddler in the Bluetooth Neighborhood but will not pair.\\ **Solution**: Reset pair table by typing N+S R000.  You will need to re-pair the Twiddler with any other device you have paired with in the past. \\ \\

+  - **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 Bluetooth 2.1+EDR. Install a Bluetooth device that supports Bluetooth 2.1+EDR like the LM506. https://www.tekgear.com/lm506.html  \\ \\
 ====USB Drive====
-  - **Problem**: USB Drive does not mount. \\ **Solution 1** : Make sure the  Twiddler3 power switch is in the ON position.  The [[getting_started#powering_up_the_twiddler_for_the_first_time|LED can be ON]] when the switch is OFF but there will be no data connection to the host computer. \\ **Solution 2** : 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 and the [[getting_started#powering_up_the_twiddler_for_the_first_time|LED is on]], it just means power is flowing. It could be the data lines 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.

+   - **Problem**: USB Drive mounts but is inaccessible. \\ **Solution 1** : Reformat the USB Drive.  Format in FAT with an allocation unit size of 512. (These are standard for FAT Formatting) \\
+====Config Files====
+   - **Problem**: Copy Config file to Twiddler but it is not being used. \\ **Solution 1** : After copying, disconnect the USB cable from the Twiddler to commit the copy to the Twiddler's storage. \\ **Solution 2** : check that the config version is compatible with the Twiddler firmware version. [[https://www.mytwiddler.com/doc/doku.php?id=twiddler_firmware|https://www.mytwiddler.com/doc/doku.php?id=twiddler_firmware
+]] \\ **Solution 3** : re-download file from Tuner. The Twiddler will ignore any config file that is corrupted and/or does not pass its initial validation check.  3 green LEDs will light up when changing config slots indicating that the Twiddler is using the built in default config.
