  Yeah, but some browsers will automatically change to https.

  For example, https://support.mozilla.org/en-US/kb/htt­ps-only-mode-firefox-android by default will use https only (but you can change in settings)

  https://support.mozilla.org/en-US/kb/htt­ps-only-prefs some people also enable this and haven't set an exception for the forum.

  You get it when you go to https://forum.espruino.com/conversations­/369818/ (note the https)

  According to the cert, it's only valid for *.microco.sm domain (and this is forum.espruino.com)

  Just wanted to mention that Seeed Studio put an NRF52840 in the XIAO form factor:

  Would be a good stopgap until we finally get an official MDBT50Q breakout with Espruino programmed in, if only it's in stock :P

• Alternate source for the Bangle2 charging cable

  in Bangle.js • 9 months, 3 weeks

  

  You can DIY a cable yourself with some pogo pins :) The one I did wasn't magnetic so I had to spend half an hour just pressing down on the pogo and the watch, but it shouldn't be that complicated to create a harness that can clamp down on both the watch and the pins.

• Bangle.js 2 now on KickStarter

  in News • 10 months, 3 weeks

  

  That is sad indeed. I was hoping that the kickstarter would have surprised me with new puck and pixl boards with the nrf52840 but I guess that would have to wait until the next one (or when the actual chips are back in circulation)?

  I'm not sure what "platform" refers to. Maybe I'm misunderstanding, but are you asking about alternative firmware for the nrf52832 chips? There's arduino of course, and then there's adafruit's circuitpython. You can also work with the nordic sdk directly.

  I was actually replying to @user134951 :D

  With regard to your question on comms with the internet, Gordon answered a similar question: http://forum.espruino.com/conversations/­309832/

• Is bluetooth open source

  in Bangle.js • 11 months, 3 weeks

  

  You'd be surprised that even the computer you're using has an opaque, second "brain" that nobody except the manufacturer has any idea of what it's doing (maybe even tracking you?) https://en.wikipedia.org/wiki/Intel_Mana­gement_Engine

• Is bluetooth open source

  in Bangle.js • 11 months, 3 weeks

  

  I would liken this to saying operating systems based on Linux are open source, except when you start adding binary blobs like nvidia or printer drivers.

  You can recompile Espruino to not use bluetooth (for example the stm32 ones don't have bluetooth) but the watch won't be as functional (e.g. no app store, no wireless comms).

  Nordic is the manufacturer of the microprocessor that powers the watch, and they also provide the bluetooth stack. Since they are the manufacturer, the Nordic provided bluetooth stack works best with the chip, similar to how nvidia drivers have better support than the nouveau reverse engineered drivers.

  Another tricky thing for opensource products working with wireless comms would be compliance. If you use the Nordic sdk, you can mention that in your product docs and the certification officials would know what to do (since a lot of products with the Nordic chips would usually use the sdk and they would have experience with it). If you don't, you're in for a more grueling (and possibly more expensive) certification process since you'll need to ensure your wireless energy signals don't go beyond what local laws require. Since Espruino can be used in consumer products (the only one that comes to mind right now is https://lab.ruuvi.com/espruino/ ) the product manufacturers benefit from this as well.
