1 – Prerequisites

keep this page open on your computer, you will need it as you move along the process.
don’t worry if this seems long, it’s only because the instructions are very detailed. it should not take more than few minute per device.
download the firmware from https://bitbucket.org/suunto/movesense-device-lib/. check subfolder /samples/bin/release/
select the HR wake up version, with bootloader.
make sure phone is plugged to charger
make sure the battery of the movesense is in good shape or new
if not already installed, install nrf toolbox : https://itunes.apple.com/gb/app/nrf-toolbox/id820906058?mt=8
do one device at a time. remove the batteries of the other devices.

open holon.ist
device must be connected (green) in holon.ist
tap it in the list of connected devices (second section in the list) to select it
tap the “DFU” button
the led should be solid RED on the device.
congrats, the device is ready for upgrade

very similar to point 4. but we will here flash the bootloader
click the zip file in the email and use the share dialog to import and select copy to NRF.
if needed, in the NRF app, push the “DFU” button
pop should appear : select “System Only” (we will update app in the next step)
select device (black button at bottom of the screen): one device on the list should have name “dfutarg”.
upload the file. (button “upload” in the middle of the screen)
once the updates finished, the led stays red. this is normal.
go to iphone settings, and disable and enable bluetooth. needed to reset the BT stack for next step!
