The default tinker firmware is what provides the digital/analog read/write functions to the api. If you’ve flashed a custom app to your core, it won’t have these functions anymore. You can re-flash the tinker firmware from your mobile app. if you haven’t flashed a custom firmware, try re-flashing the tinker firmware anyway and see if that fixes it.
Reflashing had no effect. The RGB LED turned magenta and eventually back to breathing cyan but the iOS app still shows the spinning progress icon on the Re-Flash Tinker button. Eventually the app reported an internal error with the Spark Cloud.
I’m lucky enough to have 2 cores. The same curl syntax (modulo device ID) worked on one while failing on its sibling. No need to try other web-side interfaces, something’s borked.
Hi Andy… same here. Although I had already tried reflashing 2 or 3 times it finally started working when I did two reflash operations in quick succession. Annoying but all working now My geeky Christmas week is saved!
The crucial thing to note, for other readers, is that if the small blue LED isn’t lit up by the reflash process it isn’t working.
Hey guys - just wanted to let you know the Spark team is aware of the issue and working on a fix. It seems like the auto-update firmware isn’t working as expected; for now, flashing the Tinker firmware from the mobile app should work.
