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
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
