Apologies if this is a real newbie question but I have ordered two packs of stickers. One pack is PCB only ( no covers) and the more recent pack have covers ( with the symbols such as bike, chair etc) . We have developed an IOS app which only works with PCB version only, All we are doing in the app is detecting and recording movement with zero stats for the covered versions.
Is there a difference in the firmware loaded which would mean only PCB works?
Do the symbols on the stickers mean a different app is loaded for each?
We plan to ship the versions with covers to our customers so it may be that we need to re-flash or for future orders be more specific in specifying the firmware that is loaded
