I attempted to runt the puck 1v91 firware update via nRF toolbox and got a notification saying the upload failed. Now the Puck won't seem to switch on. I can't get the red LED for a soft reset or the green LED.
Do you think you could check the battery voltage or try with a new battery?
It's possible that the firmware update failed because the battery ran out - re-flashing the device uses quite a lot of power
I've tried a new battery and no success. I haven't got a meter to test the battery, but it is new.
Do you have any way of getting hold of a volt meter? The only other person that reported having this problem did actually have 2 flat batteries when they tested.
If it is broken I'm happy to replace it, but it seems amazingly unlikely - even in the case that the firmware upload failed, you should be able to get into bootloader mode by inserting the battery with the button held down
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.
