Bug while calling Puck.getBatteryPercentage() in firmware v2.07 (Puck.js v2)

Hi all,

I have experienced the bug while calling Puck.getBatteryPercentage() and NRF.getBattery() in firmware v2.07, the values were 0 and -3.6, respectively. It is OK while I downgrade to v2.06. These wrong values existed only if I send my code (for my own server and service) to RAM (using Web IDE). I've tested two Puck.js devices I have. Just report the issue for the reference. Thank you all my lovely Espruino team.

Best regards

I just booted up a fresh 2v07 Puck.js and uploaded:

print(E.getBattery(), NRF.getBattery(), Puck.getBatteryPercentage());

via the Web IDE, to RAM, and I get:

100 2.84765625 100
// or if I turn LED1 on first to stress the battery
79 2.68242187500 79

So at least in a basic way it seems to be working. However it seems if I do analogRead(D2) first then I can break it even until a hard reboot...

I'll get a fix in for this now - I'm planning a 2v08 release this week so hopefully it'll be in that

Ok, cutting edge builds should now have a fix for this in, and it'll be in 2v08

Hi Gordon,

Always nice to hear from you. :)
I've downloaded 2v07.33 and upgraded to my Puck. The bug has been eliminated.
Thank you for your fix quickly.

Best regards
