If you have ShockWiz connected to your Android phone or tablet, but the device ID does not appear in the "Connect to" list of the ShockWiz App, you likely have ShockWiz connected through the Bluetooth menu under Settings. The ShockWiz App cannot detect ShockWiz devices that have been connected to your device this way.
To correct this, navigate to the Bluetooth menu of your phone or tablet and check that your ShockWiz device ID/Name does not appear in the list of connected devices. If it does, select the Device ID/Name and then select "Forget Device" to remove it. Once removed go back to the ShockWiz App and select "Connect" to search for the device. The device ID/Name should now appear in the "Connect to" list of the ShockWiz App.
