Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.

The advantage of using the Bangle is that the firmware in
jswrap_bangle.candnmea.cturns the NMEA strings received from the GPS device into espruino events. To implement the server on the B5 you would need to have an NMEA parser etc - probably too slow in Javascript so it would probably need firmware hacking - although all the software is already there for the Bangle 2. A further advantage is that the Bangle has a relatively large 350maH battery. Advantage would be that the B5 is smaller to carry around:)
