SDK for creating MetaWear apps that run in the Apple ecosystem. This is a thin wrapper around the MetaWear C++ API so you will find the C++ documentation and API reference useful.
MetaWear is a complete development and production platform for wearable and connected device applications.
MetaWear features a number of sensors and peripherals all easily controllable over Bluetooth 4.0 Low Energy using this SDK, no firmware or hardware experience needed!
The MetaWear hardware comes pre-loaded with a wirelessly upgradeable firmware, so it keeps getting more powerful over time.
- MetaWear board
- Apple ID, you can now get started for free! Once you are ready to submit an App to the App Store, you need a paid Apple Developer Account.
- Device running iOS 10.0 or later with Bluetooth 4.0
REQUIREMENT NOTES
The iOS simulator doesn’t support Bluetooth 4.0, so test apps must be run on a real iOS device which requires a developer account. Bluetooth 4.0 available on iPhone 4S+, iPad 3rd generation+, or iPod Touch 5th generation.

MetaWear is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod "MetaWear", :subspecs => ['UI', 'AsyncUtils', 'Mocks', 'DFU']
For first time CocoaPods users we have a detailed video guide.
Here is a walkthrough to showcase a very basic connect and toggle LED operation.
First, import the framework header files like this:
import MetaWear
import MetaWearCpp
Then add the following code wherever appropriate to make the LED flash green:
MetaWearScanner.shared.startScan(allowDuplicates: true) { (device) in
// We found a MetaWear board, see if it is close
if device.rssi.intValue > -50 {
// Hooray! We found a MetaWear board, so stop scanning for more
MetaWearScanner.shared.stopScan()
// Connect to the board we found
device.connectAndSetup().continueWith { t in
if let error = t.error {
// Sorry we couldn't connect
print(error)
} else {
// Hooray! We connected to a MetaWear board, so flash its LED!
var pattern = MblMwLedPattern()
mbl_mw_led_load_preset_pattern(&pattern, MBL_MW_LED_PRESET_PULSE)
mbl_mw_led_stop_and_clear(device.board)
mbl_mw_led_write_pattern(device.board, &pattern, MBL_MW_LED_COLOR_GREEN)
mbl_mw_led_play(device.board)
}
}
}
}
Now run the app!
