HEX vs ZIP firmware?

The latest builds of Pixl firmware are in HEX format. Are these able to be flashed to the device from the nRF Connect app?

Thanks for letting me know - no, they can't be flashed. I think they issue may be that the cutting edge builds have become too big for the flash memory available.

I'll try and get this sorted ASAP

I know you're busy right now, no worries, but as a Dev-Ops guy I'd be glad to pitch in if it's a build pipeline thing.

Thanks! Sadly I think it's actually just that recent additions for Bangle.js have bumped the firmware size up - so I need to find a way of saving a few bytes :)

Actually I take it back - it's to do with Python versions! pip install nrfutil failed

The stupid thing is that in https://travis-ci.org/github/espruino/Espruino/builds/667143007, pip install nrfutil worked for BANGLEJS and failed for everything else!

So yes, if you're able to help figure it out, it'd be great! I just tried pushing something forcing a higher Python version, but I guess we'll see if that fixes it or breaks everything :)

I went to take a look at the travis logs and noticed you already made a change to update to python 3.6 on the travis build and subsequent builds succeeded, so it looks like it's good to go!
