Thr 2019.12.26

While assisting Alex with a charging issue: forum post Charging found a bit of time to play with this Beta prototype. (pledge backer 258)

Read over the following pages:

Started with: Just got your Bangle.js? Here's how to get started

ref https://www.espruino.com/Bangle.js+Getting+Started

Am able to power on BTN1 and power off BTN2
Am able to reset holding both buttons

Loaded the following:

ref https://banglejs.com/apps/

Bootloader
Settings
Battery Level Widget
Bluetooth Widget
Mixed Clock

Pressing BTN3 after disconnect does reboot and a clock face, BLE icon and Battery status indicator are visible

ref https://www.espruino.com/Bangle.js+Getting+Started
Bullet 2 'BTN2 : ‘Select’ in menus, or bring up menu when in Clock'

However, pressing BTN2 does absolutely nothing, no menu. Bewildering.

Q: What does 'When in Clock' really mean? Is there a specific clock that must first be loaded?

First and second line here, pressing the middle button does not bring up a menu either

nor is there any type of scrolling. The clock face remains static. (minutes do update)

From WebIDE >> Settings >> Console

FIRMWARE: Current 2v04.218, Available 2v04.218

>E.getBattery()
=63

Connecting using the WebIDE reveals this error:

Uncaught Error: Function "setLCDOffset" not found!
 at line 1 col 8
Bangle.setLCDOffset(0);Bangle.setLCDMode("direct");g.clear()...

I'll keep reading / trying . . . .
