Connection Settings

Configure how Treadmill Assistant connects to your treadmill.

Accessing Connection Settings

  1. Go to Settings tab (gear icon)
  2. Find BLE Connection section
  3. Configure auto-connect and device sorting

Connection Settings

Auto-Connect

Automatically connect to your last-used treadmill when the app launches.

How It Works

With auto-connect enabled:

  1. Open the app
  2. App searches for your last-connected treadmill
  3. Automatically connects when found (3-5 seconds)
  4. Ready to work out without manual connection

Enabling Auto-Connect

  1. Go to Settings > BLE Connection
  2. Toggle Auto-Connect to Last Device ON
  3. Next time you open app, it auto-connects

When Auto-Connect Works Best

Ideal scenarios:

  • You always use the same treadmill (home setup)
  • Treadmill is nearby when opening app
  • You want fastest possible startup

Less ideal scenarios:

  • You use multiple treadmills (gym, home, etc.)
  • Treadmill is often off when opening app
  • You prefer manual device selection

Auto-Connect Behavior

If last treadmill found:

  • Connects automatically
  • Connection usually completes in 3-5 seconds
  • Main screen shows connected state

If last treadmill not found:

  • App searches for 10-15 seconds
  • Times out and shows "Connect" button
  • Tap "Connect" to manually scan and choose device

Disabling Auto-Connect

To manually select treadmill each time:

  1. Go to Settings > BLE Connection
  2. Toggle Auto-Connect to Last Device OFF
  3. App will show "Connect" button on startup
  4. Tap to scan and select treadmill manually

Device Sort Order

Choose how discovered treadmills are sorted in the device list.

Sort Options

Last Used (Default)

  • Most recently connected treadmill appears first
  • Others sorted by signal strength
  • Best for: Regular treadmill users

Alphabetical

  • Devices sorted A-Z by name
  • Consistent order every time
  • Best for: Multiple treadmills with memorable names

Changing Sort Order

  1. Go to Settings > BLE Connection
  2. Find Device Sort Order
  3. Select:
    • Last Used (recommended)
    • Alphabetical
  4. New scans use selected order

Sort Order Setting

When to Use Each

Use "Last Used" when:

  • You primarily use one treadmill
  • You want your regular device at the top
  • Signal strength matters (closer devices higher)

Use "Alphabetical" when:

  • You use multiple treadmills regularly
  • Treadmills have clear names (e.g., "Treadmill-1", "Treadmill-2")
  • You prefer consistent, predictable ordering

Connection History

The app automatically remembers all devices you've connected to.

What's Remembered

For each device:

  • Device name (e.g., "FS-7B4AC5")
  • Device Bluetooth ID (unique identifier)
  • Last connection timestamp
  • Connection success/failure history

Why This Matters

  • Auto-connect uses last connected device
  • "Last Used" sorting relies on connection history
  • Quick reconnection to known devices

Clearing History

Currently no way to manually clear connection history.

To start fresh:

  • Reinstall the app (loses all data)
  • Or just ignore old devices (they won't appear in scans if not nearby)

Bluetooth Permissions

Required Permission

Treadmill Assistant needs Bluetooth permission to scan and connect.

Granting Permission

On first launch:

  1. App requests Bluetooth permission
  2. Tap "Allow" to grant
  3. Without permission, app cannot connect

If Permission Denied

If you denied Bluetooth permission:

  1. Open iOS Settings
  2. Scroll to Treadmill Assistant
  3. Toggle Bluetooth ON
  4. Return to app

Connection Range

Bluetooth Range

Typical Bluetooth Low Energy (BLE) range:

  • Optimal: Within 10 feet (3 meters)
  • Maximum: Up to 30 feet (10 meters) with line of sight
  • Obstacles: Walls, metal, and interference reduce range

Improving Connection

For best results:

  • Keep phone near treadmill (within 10 feet)
  • Remove obstacles between phone and treadmill
  • Avoid interference from microwaves, Wi-Fi routers
  • Keep phone charged (low battery affects Bluetooth)

Connection Speed

Factors Affecting Speed

Connection time varies based on:

  • Treadmill state: Idle treadmills connect faster
  • Bluetooth traffic: Fewer devices = faster connection
  • Distance: Closer = faster
  • Auto-connect: Slightly slower than manual (searches first)

Typical Times

  • Manual connection: 2-5 seconds
  • Auto-connect (found): 3-7 seconds
  • Auto-connect (not found): 10-15 seconds timeout

Multiple Devices

Using Multiple Treadmills

If you use different treadmills:

With auto-connect ON:

  • App connects to last-used treadmill
  • May not be the one you're near
  • Manually disconnect and select correct treadmill

With auto-connect OFF:

  • Manually select which treadmill each time
  • More control, slightly slower startup

Recommendation: Disable auto-connect if using multiple treadmills regularly.

Switching Treadmills

To switch to a different treadmill:

  1. Disconnect from current treadmill by turning it off.
  2. Go to Main Screen to get access to connection details
  3. Tap "Search" button or
  4. Select new treadmill from scan results

Offline Mode

Using App Without Connection

Can access history without treadmill:

  1. On connection screen, tap "Offline Mode"
  2. Navigate app freely
  3. Cannot start workouts in offline mode
  4. Can view/delete past workouts

Useful for:

  • Reviewing history at home
  • Managing workouts
  • Checking stats

Troubleshooting Connection Settings

Auto-Connect Not Working

Problem: App doesn't auto-connect to treadmill

Solutions:

  • Verify auto-connect is enabled
  • Ensure treadmill is powered on before opening app
  • Check treadmill is within Bluetooth range
  • Wait 15 seconds for timeout, then connect manually

Wrong Treadmill Auto-Connects

Problem: Connects to wrong treadmill (e.g., neighbor's)

Solutions:

  • Disable auto-connect
  • Manually select your treadmill each time
  • Move other treadmills further away or power them off

Cannot Find Treadmill

Problem: Treadmill never appears in scan

Solutions:

  • See Connection Troubleshooting
  • Verify treadmill Bluetooth is enabled
  • Check Bluetooth permissions granted
  • Restart treadmill and app

Device List Empty

Problem: Scan finds no devices

Solutions:

  • Check phone Bluetooth is enabled (Settings > Bluetooth)
  • Grant Bluetooth permissions to app
  • Ensure treadmill powered on and idle
  • Move closer to treadmill
