Can a Researcher Use One iOS Device with Multiple Skyns?

Updated

It is possible to use one iOS device with multiple Skyns, especially if the Skyns are used and connected to the Skyn app in non-overlapping time windows. But, it is not recommended to use one iOS device with two Skyns collecting and uploading data at the same time.

In all cases, for best results, it is preferable to pair one unique Skyn to one unique wearer account and iOS device because this ensures data will be continuously uploaded from the Skyn to the correct account. Because the Skyn app can only connect to one Skyn at a time, if more than one Skyn is paired to a single iOS device, the researcher or user will need to manually ensure the app alternates which Skyn gets connected and uploads data. This could result in some data being overwritten if wearers are not careful.

If pairing one iOS device with multiple Skyns is necessary, please follow the guidelines below.

  1. First, make sure only one Skyn is powered ON at a time (The first Skyn will be designated Skyn A)
  2. With only Skyn A ON, following the pairing instructions in the Skyn app
  3. Once Skyn A has successfully paired and the researcher confirms data is being collected and stored, power Skyn A OFF
  4. Then, force close the Skyn app
  5. Re-open the Skyn app, and confirm no Skyn is connected from the home screen. Then, tap the settings icon on the bottom right, and select 'Pair New Device'
  6. The user will be prompted on the next screen to 'Prepare Your Skyn'
  7. Follow the instructions to press and hold the second Skyn (designated Skyn B) to turn that Skyn ON and put it into pairing mode
  8. Once Skyn B is in pairing mode, follow the instructions to accept the pairing
  9. Both Skyns (A and B) are now paired to the singe iOS device. The user can then turn Skyn A ON, and begin recording data from both devices
  10. Please remember to check which Skyn is connected in the Skyn app. To switch between which Skyn is connected, the user can alternate briefly turning one and then the other Skyn OFF, remembering to confirm each Skyn serial gets appropriately connected to the Skyn app and syncs it's data
