Troubleshooting

This page covers problems with the physical suit itself: fit, electrode contact, sensors, and power. If the symptom is about pairing, connection, updates, or calibration behaviour in the apps, see Control Center - Troubleshooting. If it's about Studio behaviour (avatars, presets, capture), see Studio - Troubleshooting.

No haptic sensation, or it's very weak#

1. Check that the electrodes have full, flat contact with bare skin. Even a slight angle or a loose fit can prevent stimulation. See Hardware - Wearing.
2. Confirm nothing is between skin and electrode, and that any underwear worn underneath has no metal parts.
3. Best contact happens when skin is slightly moist. Do a few light exercises to perspire; don't pour liquid on your skin.
4. Confirm haptic calibration has been done for this session in Control Center - Calibration. Without calibration, sensation is set to conservative defaults (1% MIN, 30% MAX) and can feel imperceptible.
5. Check global haptic power in Control Center isn't set too low. It multiplies every animation's power before minimum/maximum limits are applied.

If one specific body area (for example a single channel or zone) never produces sensation while the rest of the suit works normally, that's more likely a hardware fault in that zone. Note the affected channel and see When to contact support below.

Avatar doesn't move correctly, or mocap drifts#

1. Recalibrate. 6-axis mocap calibration is not saved between sessions and must be redone after every Studio restart, or whenever the avatar stops reflecting your movement correctly. See Studio - Data Capturing.
2. If you're using 9-axis mode, move away from ferromagnets and large metal objects. They interfere with the magnetometer this mode depends on. See Concept - Mocap.
3. Make sure the I-pose used for calibration was clean: full height, hands straight by your sides, feet hip-width apart and flat.
4. Long recordings drift more, since drift accumulates over time. This is expected behaviour of 6-axis mode, not a fault.

Power bank or connector issues#

1. Check the power bank for visible damage before connecting it. Don't connect the suit to a damaged power bank.
2. Confirm the power bank is charged and meets the required specification (capacity, output). See Hardware - Specifications.
3. Reseat both USB-C cables: the shorter cable between power bank and jacket, the longer cable between jacket and trousers. See Hardware - Wearing.
4. If the suit doesn't power on with a known-good, charged power bank, that points to a hardware fault. See When to contact support.

Biometry (PPG) readings missing or inaccurate#

1. PPG measurements are extremely sensitive to sensor-to-skin contact. Recalibrate every time you put the suit on, not just once. See Concept - PPG.
2. Confirm the sensor sits on the outer surface of the right shoulder, where the deltoid muscle ends.
3. Confirm your device version actually carries a PPG sensor (TESLASUIT from version 4.5.6).
4. Stay still for the full calibration countdown. Movement during the sample recording invalidates the calibration.

Suit feels different between sessions#

Haptic sensation depends on individual skin properties (galvanic skin response), which vary session to session. This is expected and is exactly why calibration exists — recalibrate rather than treating it as a fault. See Concept - Haptics and Hardware - Wearing.

Not a hardware issue?#

• Drops connection, won't pair, or won't update → Control Center - Troubleshooting
• Device not showing up in Studio, no haptic felt during preset playback → Studio - Troubleshooting

When to contact support#

Contact support@teslasuit.io if:

• A symptom is isolated to one specific channel, node, or sensor while the rest of the device works normally.
• A fault persists after eliminating fit, contact, calibration, and power causes above.
• You see physical damage to the fabric, electrodes, or connectors.

Include with your message:

• The affected channel, node, or area.
• Your device's hardware and firmware version (see Control Center - Device Report).
• What you've already tried.
