I have had some problems connecting with Web Bluetooth on Chrome after a while that just requires a restart of Chrome. As it's often my main browser, this can be a pain.
So, try installing Chrome Canary just for Bangle / Espruino so it can be restarted easily. I've taken care not to install any extensions or do Google log-in on Canary, so there are no bookmarks or other distractions. That way, I'm less likely to accidentally use Canary for other things.
