I'm having difficulty updating the firmware on my puckjs. Once in DFUTarg mode;
Have you tried a fresh battery? The DFU update uses quite a lot of power, so if your battery is on the way out then the DFU process can cause the battery voltage to drop too low, which will make Puck.js reboot
I left the battery out over the weekend and when I tried updating it today it worked first time.
Great! It'd be worth checking 'Puck.getBatteryPercentage()` to get an idea how full it is - if it's running right down then stuff like the Magnetometer might not work.
Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.
