SDK Mode feature

  • Polar Verity Sense (starting from firmware 1.1.5) has now feature called SDK Mode. The SDK mode is the state which makes available the full capabilities of the sensor, i.e higher sampling rates, wider (or narrow) ranges etc. For example, in the SDK mode the accelerometer sampling rate can be chosen from values 26Hz, 52Hz, 104Hz, 208Hz or 416Hz compared to 52Hz available in normal operation mode.

How to use SDK Mode

  • first of all you need to update the Polar Verity Sense sensor to firmware 1.1.5. Which can be done by registering the sensor to Polar Flow ecosystem, see the help
  • Polar BLE SDK provides new API's which are used to enable/disable the SDK mode
  • once the SDK mode is enabled you may start the data streams as in normal operation mode

Good to know about SDK Mode

  • you may read all the capabilities in the device with the requestFullStreamSettings function in any operation mode. However, before starting the stream in any operation mode it is good practice to read currently available settings with requestStreamSettings function.
  • if starting many streams on high frequency at the same time, it cannot be guaranteed that all the data is sent over the Bluetooth as traffic may get too high

iOS SDK updates:

func enableSDKMode(_ identifier: String) -> Completable

func disableSDKMode(_ identifier: String) -> Completable

func requestFullStreamSettings(_ identifier: String, feature: DeviceStreamingFeature) -> Single<PolarSensorSetting>

Android SDK updates:

public abstract Completable enableSDKMode(@NonNull final String identifier);

public abstract Completable disableSDKMode(@NonNull final String identifier);

public abstract Single<PolarSensorSetting> requestFullStreamSettings(@NonNull final String identifier, @NonNull DeviceStreamingFeature feature);
