See our support post for why we made this change at https://structure.io/r/uplink - Support for updating firmware on Original Structure Sensor from v1.0.0 to v2.0.0 has been removed in this version of Structure App. If you still need this functionality for whatever reason, please reach out to our support team at [email protected] Known Issues: - Due to a bug in firmware version 0.9.8 on Mark II devices, the sensor may crash and run out of memory while attempting to update firmware to 0.9.9 which results in an unsuccessful update message. If you receive this message, please try the update again. This usually happens if the sensor has been connected and streaming for some time before the firmware update is started. For best results, start the firmware update process as soon as possible after plugging your sensor in to an iOS device for the first time. 2.0 12/09/2019 Structure App 1.10.2: - Structure App now supports Structure Sensor (Mark II).

It contains the 2.0 firmware update for the Structure Sensor, and also includes all the changes from the 1.3 version, listed below. Here are some of the highlights of Firmware 2.0: • Laser distortion correction is now more advanced, and depth is more smooth as a result. The new method eliminates vertical lines in depth images.¹ • Structure Sensor's depth output now dynamically changes scale when the iPad color camera refocuses.¹ • Depth frames can now synchronize to iPad Air full-resolution color frames at 24FPS. • An internal timer that limited sensor streaming to 9 hours or less when using OpenNI2 has been fixed. • Overall Structure Sensor reliability is improved, and many minor bugs have been squashed. Other app improvements: • Depth display is more crisp (2X resolution). We hope you enjoy the new update! --- ¹ Requires apps built with Structure SDK 0.5 or above. 1.3.2 01/19/2016 This version fixes a rare issue that would cause certain sensors to reboot unexpectedly.
