There is no user calibration required on the sensor. Is the sensor pretty new or one of kickstarter devices? On Kickstarter devices firmware update is recommended https://lab.ruuvi.com/dfu/ (both April version and Beta can be used on model +).
IOS 11.0.3 Chrome no longer works with Ruuvi, your instructions no longer work. How can I upgrade the Kickstarter firmware with my IOS devices or my Raspberry Pi 3/Zero W please. Please can you give me proper instructions not a generic video with half the instructions missing.
There are video instructions on the https://lab.ruuvi.com/dfu/ page.
Anyway, Hold “B” and press “R” button to enter bootloader.
RED led stays on while you’re in bootloader mode. Upload the DFU package to “RuuviBoot” device using nRF Connect or nRF toolbox
No. The video STARTS half-way through the process. How do I get to where the video starts (at the start of the video?) please? The video is fine but it does not start at the beginning of the process! DO you understand me? Imagine the process, from start to finish (for a beginner), and then the video starting to record half way through the process - that is what I mean. Nothing wrong with the video or playback but the whole of the process is not recorded/documented.
