hi, is any chance with espruino boards to use pdf simple files and convert them to display at lcd, tft or epaper displays?
i am not thinking about diy ebook reader but about road book reader, like is used for enduro or Dakar styles rallies, there are simple navigation information based on a simple character and signs system,
those road book maps are usally available and also can be created by user,
issue is the sun, any tablet or present navigation system are most not epaper made what is
bad for reading during the rally, sometimes is necessary to even stop to read the map,
with epaper it should be much better for visibility of the data on the screen
didn't finy any roadbook reader at the market with epaper and possibility to read pdf files

I've just got my first MDBT42Q to try play with, after all customs and postage process which was an extra effort, during first time i wanted connect it I probably fried it.
I know there is written warning to check polarity, I wanted to connect it via usb/ttl converter as my macbook doesn't support ble. I don't know how I did it, I checked wiring few times and finally connect it wrong.
I know, my mistake, but from my point of view board for 20GBP should have protection against wrong polarity. I remember I made wrong connection with pico, but there is rectifying diode, I changed it and pico is still working.
It's pity I can't play with ble again, MDBT42Q is fried, and Bangle.js I ordered can't connect with any of my 4 computers (they don't support ble, also few dongles USB I have). Unfortunatelly again I have to make step back and come back to arduino for another few projects, my next attempt to switch to espruino failed.
I appreciate any advice how to connect my Bangle.js (1st version) over bluetooth in some reliable way.
I use it with macbook pro a1278, also I have ZEXMTE usb bluetooth dongle to work with it. I did checked another 3 dongles but without success.
My macbook onboard bluetooth can connect with this watch let say one per 100times.
When I use ZEXMTE dongle I can get connection every 20-30 times, also it not keeping it for long,
after while it disconnect it.
I use espruino Web IDE as described here https://www.espruino.com/Troubleshooting+Bangle.js .
Any advice how to make this connection work?
