iOS SDK Change Log

[4.1.0] - 2026-09-04​

iOS SDK 4.1.0 (FW 8.65)

Added​

  • Guided flows (Wearing Optimization and Blood Pressure Initialisation) are now translated into all 17 supported languages. The host application must list the languages in its Info.plist (CFBundleLocalizations) for them to be used.
  • Cuffless bracelet blood-pressure spot measurement — start/stop API with the measurement result returned to the integrator.

Changed​

  • Embeds firmware 8.65 for the 287-2B bracelet.
  • Licence-key enforcement hardened for third-party builds: the licence check is now performed inside BLE initialisation so it cannot be bypassed, and offline use is granted only from a previously validated licence cached securely in the Keychain instead of being allowed on a network error.
  • Faster data delivery at the default 1-minute activity sampling rate: activity records are now retrieved one at a time instead of in batches of three, so measurements reach the cloud continuously instead of in 3-minute bursts.
  • Firmware update recovery: a bracelet left in bootloader mode after an interrupted update is now detected directly and the update resumes from where it stopped, instead of waiting for the bootloader to time out.
  • Firmware update resume now reuses the firmware package originally selected, so study-specific firmware resumes with the correct image.
  • Safer synchronisation of the daily summaries (activity, heart rate, blood pressure, SpO2, respiration rate, skin and core body temperature) when records are removed while an upload is in progress.
  • Additional robustness: wearing-optimization alerts are now driven by the firmware, the sleep wake-up time window has been relaxed, invalid height values are rejected, and the SDK now logs a warning when the applied device plan would stop the bracelet from measuring.

Fixed​

  • Fixed a Bluetooth authentication issue on a first or stale bond that made secured commands time out and the connection drop and reconnect.
  • Fixed a second firmware update being started while one was already running, which caused the update to fail with a connection error.
  • Fixed a crash and reduced memory pressure during large data synchronisations.

[4.0.0] - 2026-07-08​

Guided setup flows are now bundled as self-contained SwiftUI modules.

Added​

  • WearingOptimizationView — the whole Wearing-Optimization flow (preparation → instructions → running → retry → success/failure) as one SwiftUI view. Present it, pass a result callback; the SDK drives the bracelet. See the Wearing Optimization guide.
  • BPInitializationView — the NIBP (blood-pressure) calibration flow bundled the same way; the host supplies cuff readings through a cuffProvider closure. See the Blood Pressure guide.
  • NIBP spot-measurement results (cuffless bracelet BP).
  • Mac Catalyst compatibility.
  • FW 8.48 for 287-2 bracelet.

Changed​

  • Secured BLE connection (requires FW 8.41+).
  • New Corsano sleep pipeline.
  • Improved PPG2 sync after ECG and NIBP-spot measurements.
  • Reduced memory pressure during raw-PPG sync.
