There are two collection modes when recording with the IMeasureU app: streaming and on board.
Streaming is ideal when instant information is required and the sensor is staying within a close proximity of the device it is streaming to. On board recording is ideal when a higher sampling rate is required and/or the sensor will not be within the proximity of the IOS device for part of the recording.
The details of the two modes can be seen in the table below:
|Data Storage:||Streamed directly to device via Bluetooth||Stored on the IMU internal memory|
|Accessing Data:||Email from app OR upload to iTunes||Download via the Lightning Desktop App|
|# of Sensors:||4 sensors streaming across a single trial||8 sensors across 2 active trials|
|Frame Rates:||3-Axis at 500Hz9-Axis at 100Hz||3-Axis at 1000Hz9-Axis at 500Hz|
|Synchronisation:||Time vectors of all sensors sync-ed||Time sync information relayed to app when in range of IOS device|
