LilyGo TWatch 2020 lunokIoTWatch firmware

Buy me a coffe!

Last videos from development

Video test:

"CAN YOUR SMARTWATCH RICKROLL?" * Shinoa Fores

3D engine:

IA driven freehand character recognition (can learn your own patterns):

• Note: under heavy development (not ready for everyday use)

• Supported devices:

• lilyGo TWatch 2020 series v1

• lilyGo TWatch 2020 series v2

• lilyGo TWatch 2020 series v3 (both battery and UART/TTL) 380mAh and 500mAh (planned 400mAh version)

• You can set WiFi credentials ("Home>Settings>Prov") via QR using:

  • Android device: https://play.google.com/store/apps/details?id=com.espressif.provsoftap (select WiFi provisioning using WiFi)
  • Apple iOS: https://apps.apple.com/us/app/esp-softap-provisioning/id1474040630

• The BluetoothLE pairing can be archieved via "Home>Settings>Pair" can use BatON https://play.google.com/store/apps/details?id=com.limi.baton on Android to remote battery monitoring

• Can use Gadgetbridge https://www.gadgetbridge.org/ and receive android notifications on watch (use "BANGLEJS esprunio" as device)

Build, upload & flash:

• First take care about what hardware version have (at this time 1,2 and 3)
• Install https://platformio.org/install/cli

Don't bother me, give me fast:

$ git clone https://github.com/lunokjod/watch.git
$ cd watch
$ touch openWeatherKey.txt
$ pio run -e Release-twatch2020_V3 -t upload
$ pio run -e Release-twatch2020_V3 -t uploadfs

• Replace '_V3' with your watch version

Update from earlier version:

$ git fetch
$ git reset --hard HEAD
$ git merge '@{u}'
$ pio run -t clean
$ pio run -e Release-twatch2020_V3 -t upload
$ pio run -e Release-twatch2020_V3 -t uploadfs

• Replace '_V3' with your watch version

Basic usage:

• Use button to wake/sleep the watch
• When screen goes on, the watchface appears
• Long button push for poweroff

What does:

• WiFi time sync once every 24h (using network time protocol NTP)
• WiFi weather sync every 30 minutes, needs online account (set your openWeather key in "openWeatherKey.txt" at same level as platformio.ini before build) more info: https://openweathermap.org/
• Wake up every 15 minutes to monitor the user pose (future sleep monitor)
• Wake up every activity (steps monitor app Home>Steps)
• BLE GATT support
• Pairing with random pin (see "Home>Settings>Pair" on main menu)
• Remove current bonded devices
• BLE Battery standard notification. Can use BatON https://play.google.com/store/apps/details?id=com.limi.baton on Android to remote battery monitoring
• Man in the middle resistant (BLE)
• Color themes
• Multiple watchfaces (call for designers!)
• Screen orientation
• OTA update (wireless)
• Gadgetbridge compatibility (BangleJS-esprunio) for android/iOS notifications
• Media player
• Handwritting trainable keyboard
• BLE zone location
• omdb Posters api
• Launch lamp on gesture (put your arms down and double tap or PEK)
• Deep sleep: Put your watch with the screen ON facing to plane surface and the stripes points up
• Wakeup: Simply wear-it on your wrist, the watch boots up, PEK and doubleTap already works
• Lua scripting
• UI rich controls with layouting via (LuI)
• 3D engine control on LuI
• Handwritting reconeisance

Full application list:

OUTDATED

See outdated app gallery

Hardware support:

• BMA423 support (including during sleep)
• AXP202 support (including sleep)
• haptic and vibration support
• ST7789V support (lilygo TFT_eSPI)
• Partial RTC support (system sync)
• MAX98357A (mp3 playback support)
• WiFi (via provisioning)
• BLE (work in progress) issues while wifi is in use
• IR work, but only can send with this hardware (useless by now, I want to do jokes!)

Pending to implement:

• Multiple apps (seamless)
• Add first launch application assistant to set or omit the desired setup parts
• PDM Mic (voice assistant)
• RTC (alarm features)
• espNow (locate other family watches, icon chat availiable)
• Custom activities (hidden app availiable for testing)
• feedbacked apps (what do you need?)
• Web installer: https://espressif.github.io/esptool-js/
• User customizable night hours, during this time, the system don't allow to reply anything inmediatly(delayed send guarantees don't send stupid messages to others by accident)
• Menú must remember the last used or better: reorder the list with user preferences (app usage counters)
• hive mode (wireless mesh, share info with other lunokIoT, without infrastructure)

Important build flags

platform.ini file contains the build flags, the more relevant are:

• -DLILYGO_WATCH_2020_V3 change with your version (lilygo library driven) please report issues :)
• -DLOG_LOCAL_LEVEL=ESP_LOG_VERBOSE esp-idf debug shit
• -DLUNOKIOT_DEBUG generic system debug messages
• -DLUNOKIOT_DEBUG_APPLICATION allow use of lAppLog()
• -DLUNOKIOT_DEBUG_EVENTS System events specific debug messages
• -DLUNOKIOT_DEBUG_UI UI specific debug messages
• -DLUNOKIOT_DEBUG_NETWORK Network specific debug messages
• -DLUNOKIOT_SILENT_BOOT dont shake and no fanfare sound when start/stop
• -DLUNOKIOT_WIFI_ENABLED start the wifi timed connection subsystem
  • -DLUNOKIOT_UPDATES_ENABLED check lastbuild on github and warn about the update
• -DLUNOKIOT_BLE_ENABLED start the ble subsystem
• -DLUNOKIOT_SCREENSHOOT_ENABLED Allow to do screenshoots (touch 5 seconds to use it)
• -DLUNOKIOT_SERIAL Enable serial comms via UART 115200bps (output log)
• -DLUNOKIOT_DEBUG_UI_DEMO Enable a bunch of demo applications about graphics

Common problems:

Build failed: "NO WEATHER KEY FILE FOUND, ABORT BUILD"

• If you don't have a openweather account get it one and generate a user key
• Put the key on "openWeatherKey.txt" (yes, camelCase)
• Try to build again

Clock don't show nothing on screen

• is a V3 device?
• Review the build list of platformio and select RELEASE and your version V_1,V_2,V_3...

Know problems

• Touch are unstable meanwhile calibration is running (some seconds after boot)

Warning:

Advice about usability: This software is under heavy development and erlier development phase... many parts can be disfunctional, broken or buggy

Advise about privacy: This software (as device does) can monitor your activities (for fitness applications purposes) and isn't shared outside

Advise about warranty: Absolutely no warrant about nothing, use at your own risk
