Converting app to Bangle.js 2

So taking the doztime code from github and uploading to the emulator as Bangle2 (or to the Bangle2 itself) I get the following errors:

Uncaught Error: Function "sleep" not found!
 at line 4 col 45 in .boot0
if (!NRF.getSecurityStatus().connected) NRF.sleep();

...(){ toggleTimeDigits(); }, BTN4, {repeat:true});
                              ^

...(){ toggleDateFormat(); }, BTN5, {repeat:true});

So NRF and setLCDMode are to be expected because the emulator does not have NRF and the Bangle2 does not support LCD modes.

And the others are related to the button definitions that are not supported on the Bangle2 either.

But you could work around with that probably by using above code from Gordon.

Not sure why you are seeing different errors. Maybe some browser caching issue?
