External sensor integration

By Andriy Herts, Nataliia Herts

Update Firmware message

By Patrick Quille

Hi, We currently have 2 beta photosync devices. Today when using both devices we got error messages on our phones saying update firmware (v1.01 to v1.04). Where do we need to go to find these firmware updates? Also our computers do not recognise the devices through the usb connection. Is there aditional software we must download to allow this? Thanks, Patrick
