Battery level

SteveOD

In xCode for iOS, an older example to read the battery level is

    device.readBatteryLifeAsync().success { result in
        self.batteryLevelLabel.text = result.stringValue
    }

I cannot seem to find this function in the latest MetaWear API.

Please advise.

Hi Eric,
Thanks for that. Is there a Swift equivalent to the C++ code ?

gowtham

pls share the swift code

Laura

@gowtham, you need to write the swift code yourself.

let battery_signal = mbl_mw_settings_get_battery_state_data_signal(DiagnosticVC.deviceBoard.board)

    mbl_mw_datasignal_subscribe(battery_signal!, nil) { (context, data) in
         let state = MblMwBatteryState()
        print(state.charge)
    }

    mbl_mw_datasignal_read(battery_signal)
