flashing espruino+ninebot/eucWatch to a P8 smartwatch

Flashing espruino+eucWatch (formerly ninebot-one)

[updated]

Intro: 

Espruino: is javascript engine ported to nrf52 and P8 (fanoush)

Ninebot-one (nb): is a watch software that besides time, has some additional functions, especially the one that originally gave name to the software, a "page" that displays info from a unicycle mobility device.

eucWatch: latest version and new name for the Ninebot-one software

ATCwatch: another software for P8 based in Arduino (see other articles of this blog)

Steps:

1) Flash bootloader

1.1) if you have Dafit/stock ROM

or 

1.2B) if you have ATCwatch installed on the P8  

2) Daflasher step

3) Espruino step (PC and Chrome)

Configuring/coding nb espruino:

Using nb/ninebot UI

  

From a browser download following apps from github

• DaFitBootloader23Hacked.bin (A custom Bootloader using the preInstalled SoftDevice5.0.1)

• FitbootloaderDFU2 zip    (Soft Device 2)
• espruino_2v0x.xxx_p8_SDK11_SD20.zip  (from fanoush github page for p8)
  

If you start from p8 default status/Dafit stock then you have to install before the first 2 files.

 1) Flash bootloader

1.1) if you have Dafit/stock ROM 

 You must install before:

    DaFitBootloader23Hacked.bin

    FitbootloaderDFU2 zip 

(common steps with flashing ATCwatch)

 

On Daflasher

Select: P8 

(wait until button "Select File" is enabled)

Select File : DaFitBootloader23Hacked.bin

P8 screen [green screen, progress bar and end in 3 color squares]

Select: ATCdfu
Click button "Do DFU Update"
Selectfile: FitbootloaderDFU2 zip [check Use Nordic Bootloader]

(it can take a long time, fail several times during the process and recontinue from last %. But at the end it should complete flashing the file, speed is slow i.e 2,20kB/s)

  P8 screen    [red square and ATCnetz.de]

 

1.2) if you have ATCwatch installed on the P8

From p8 menu, Click "Bootloader"

  P8 screen    [red square and ATCnetz.de]

 

2) Daflasher step

At BLE devices list

Select: ATCdfu

Click button "Do DFU Update"
   [Checked box: Nordic bootloader]
   [Unchecked box: Toggle Bluetooth]
Select DFU file:  espruino_2v0x.xx_p8_SDK11_SD20.zip  

3) Espruino step (PC and Chrome)

(only tested on Windows) 

    Bluetooth has to be on

•     from Chrome (tested in v84):  https://www.espruino.com/ide/#

   "Connection Icon", "Web Bluetooth", P8 xxxx

   on left side terminal type:

             "require("Storage").eraseAll()"

 

•  how to Flash /Upload "init" file   
  
  

Having  right side windows clear (empty of code)

Drag an drop "init" file to left side (

Click on Send to espruino arrow down icon, choose Upload destination, "Storage" , choose name ".bootrst"

 Click on ".bootrst"

 

•   (optional) Edit "handler" file before upload 
  

Depending on P8 model, touch and accelerator controller can change

 

for example for a P8a/TFK5 set

      const touchtype="716" and acctype="BMA421"

 whereas a P8b can be a touchtype="716" or "816S" and acctype="SC7A20"

• Upload files
  

[enter in DEV mode]

  type on the left side:     reset() ,   [press enter while holding the button on the p8]

 

>reset()

=undefined
Welcome!
*** DevMode ***
Short press the side button
to restart in WorkingMode

•    Click on Storage/HD icon (Access files in device's storage),   "Upload a file":  handler, main, settings, calc,...

  (handler, main, settings, minimum files required for basic/testing)

  (euc file is not required, only for ninebot unicycle owners).

• Verify/execute
  

Click on Storage/HD icon (Access files in device's storage), verify existence of files and .bootrst

short tap on the button, and it will boot to working mode

 On left side terminal, execute command "reset()" or "E.reboot()"  (last one reset the hardware and loose the time)

DEV mode: (required for future files upload)

Do a reset() while holding the p8 button

from Settings-info- long press in restart button

 

Configuring/coding nb espruino:

During file upload, time is set on espruino. However, depending on timezone  value for an attribute, the displayed time can be wrong.

 

file: init/.bootrst  (Now .bootcde)

E.setTimeZone(2);

// 3=default

// Spain 1 winter time  2 summer time 

 

file:handler

const touchtype="716"; //716 for P8a/TFK | 816|816s for P8b

 

(for models and hardware check a previous post)  

 

Upgrading espruino

Daflasher

Chose: p8

Click "Start bootloader"

p8 screen [redsquare]

DFU 

 

Upgrading n-b (ninebot) version or many files

Erase and start from scratch

 

require("Storage").eraseAll()

connect

 

require("Storage").compact()  [???]

init to .bootrst

 

 

Using nb/ninebot UI

reset() .The normal reset, command or from p8 screen, "INF" (settings-info) menu, long hold on reboot

E.reboot() , command or from p8  holding the button for~15 secs, it will kick the watchdog 

 

TOR=Torch

AL=Alarms (for timer, hold press and will set current time+10min)

CALC= Calculator

BRI=Bright

ACC=Accelerator/step counter

HID=control over bluetooth keyb/media

CLI=enable nordic serial (required by espruino IDE webIDE)

ATC=enable to sync with d6Notification android app (time, receive commands...)

Set time. 

from web IDE: upload an empty code to RAM

from d6: re/enable notification

BLE command: AT+DT=202008251300 (2020-Aug25th13:00)
