Watch Application System in Python
Introduction
Wasp-os is a firmware for smart watches that are based on the nRF52 family of microcontrollers, and especially for hacker friendly watches such as the Pine64 PineTime. Wasp-os features full heart rate monitoring and step counting support together with multiple clock faces, a stopwatch, an alarm clock, a countdown timer, a calculator and lots of other games and utilities. All of this, and still with access to the MicroPython REPL for interactive tweaking, development and testing.
Wasp-os comes fully integrated with a robust bootloader based on the Adafruit NRF52 Bootloader. The bootloader has been extended to make it robust for development on form-factor devices without a reset button, power switch, SWD debugger or UART. This allows us to confidently develop on sealed devices relying on Bluetooth Low Energy for over-the-air updates.
Documentation
Wasp-os is has extensive documentation which includes a detailed Application Writer's Guide to help you get started coding for wasp-os as quickly as possible.
Getting Started
Wasp-os can be installed without using any tools or disassembly onto the following devices:
- Pine64 PineTime
- Colmi P8
- Senbono K9
Use the Installation Guide to learn how to build and install wasp-os on these devices.
At the end of the install process your watch will show the time (03:00) together with a date and a battery meter. When the watch goes into power saving mode you can use the button to wake it again.
At this point you will also be able to use the Nordic UART Service to
access the MicroPython REPL. You can use tools/wasptool --console
to access the MicroPython REPL.
To set the time and restart the main application:
^C
watch.rtc.set_localtime((yyyy, mm, dd, HH, MM, SS))
wasp.system.run()Or, if you have a suitable GNU/Linux workstation, just use:
./tools/wasptool --rtcwhich can run these commands automatically.
As mentioned above there are many drivers and features still to be developed, see the :ref:`Roadmap` for current status.
Community
The wasp-os community is centred around the github project and is supplemented with instant messaging via the #wasp-os IRC channel at libera.chat .
If you are unfamiliar with IRC and don't have a preferred client then we recommend connecting to libera.chat using the matrix/IRC bridge. The matrix bridge will allow us to receive messages whilst offline. Follow the link above and, if you do not already have a matrix account, register yourself. That should be enough to get you chatting!

Custom builds
Wasp-os is designed to allow users to easily create their own custom builds. Simply modify the wasp.toml file to include your favorite apps and watch faces. See the docs for more information on how to build wasp-os.
