Gadgetbridge 0.51.0: Amazfit Bip U, Amazfit Verge Lite

We do not know why Huami releases so many new devices every year. These have become too much to buy all of them, but it is always nice to have pull requests from the community, which happened for the Bip U and Verge Lite during this cycle. Thank you!

But there is a lot more to this release!

Apart from the usual bug fixes and tweaks, we overhauled the daily stats widget completely which is now much better looking and more functional.

Also device code contributors have pushed improvements, most notably the Casio GBX-100 and Bangle.js which now support activity data recording.

On building safe bridges

Cool gadgets give us some really great possibilities, like tracking our activities, controlling music and smart home devices, receiving notifications and more. But in our strive for better, faster, lighter, smarter, cheaper... we often forget the down side of our endeavors. Apps providing connections to our devices do receive all our movement information, including precise location. We have written about it previously, in 2017. But maybe you do not care about the details of your whereabouts being shared and only care about your communication. And your communication with friends and family is surely safe with secure apps that have become widely popular, right? But unfortunately, every notification that is forwarded to your smart bracelet even though you received it from some very secure, end to end encrypted app like Matrix or Signal, has been seen by the bracelet's companion app. These are closed source applications provided mostly by the vendor of the gadget and it is only up to the vendor to decide if they send these conversations to their servers for further processing. It is now up to us to decide if we want to give them fully detailed view into our lives.

Gadgetbridge 0.50.0: Initial support for Casio GBX-100

This release comes just two weeks after the previous version bump, but brings a support for a new device:

• Casio GBX-100 contributed by Andreas Böhler.

Another important new feature in this release is support for flashing watchfaces for the Amazfit/Mi Band 5. These devices support up to three custom watch faces plus two factory ones. Even though it looks easy then you know how, it took a lot of time and effort to analyze and implement this correctly.

On the user interface side, the Sports Activities got their Dashboard view revamped to better match the design of the recently added Activity List Dashboard. And, utilizing all the work done on our new sortable type of preference widget, the Charts Tabs can now be selectively enabled/disabled and also arranged as preferred by each user, independently for each device.

Gadgetbridge 0.49.0: Lots of improvements - and even more Huami devices supported!

Notes from under the bridge

Gadgetbridge 0.49.0 has been released, closing up yet another interesting period of development.It is already available on F-Droid!

New supported devices

Initial support for few new Huami devices has been added:

• Amazfit Bip S Lite
• Amazfit GTR 2/GTS 2

Thanks to contributors who own these devices and were able test and integrate the required changes into Gadgetbridge. Adding a new without us having access to the physical device can be hard, so any effort is appreciated. To make new developer's lives easier, the New Device Tutorial has been improved a lot, providing good guidance in adding a new device, storing activity data and also providing preference interface and storage.

Gadgetbridge 0.48.0: Three completely new devices supported

Gadgetbridge 0.48.0 has been tagged and will appear on F-Droid soon! As always, this can take a few days.

Six code contributors and twenty one translators have contributed more then 130 commits to the latest release of Gadgetbridge, bringing support for three new devices:

• The Sony SWR12 bands
• Lefun Smart Bands
• Nut

The Nut devices use the Nordic firmware update protocol (DFU) by using the official nordic library. This enabled us to also use it for other devices like the like the PineTime (InfiniTime), and probably more devices in the future. PineTime InfitiTime firmware's music control, being recently improved, also got improved support in Gadgetbridge. All of the work mentioned in this paragraph was contributed by Taavi Eomäe. Thanks Taavie!

Gadgetbridge 0.47.0: Pinetime-JF, big update for Huami devices

Gadgetbridge 0.47.0 has been tagged and will appear on F-Droid soon! As always, this can take a few days.

This release finally has initial support for Pinetime-JF (JF Firmware for the PineTime watch). You can check progress of the JF Firmware here. This initial support is not really usable, it only allows setting the time, displaying PineTime's software and hardware revisions, and seeing notification titles on the watch (without vibration). As the firmware improves, we plan to support new upstream feature as soon as we can.

Gadgetbridge 0.46.0: Mi Band 5 and TLW64 support

Gadgetbridge 0.46.0 has been release and after a whole week of waiting it landed in F-Droid.

This release, which adds TLW64 support contributed by Erik Bloß, also has support for the new Mi Band 5, which is basically runnig on the Mi Band 4 code.

On the Huami front there are fixes for GTR/GTS activity data on newer firmware version. There seems to be extra data which we ignore for now to make the current code run with it. In the future we will look at making use of the new data which unfortunately would need a new database schema.

Gadgetbridge 0.44.0: Initial WatchX(Plus) support and much more

Gadgetbridge 0.44.0 has been released! Let's play the F-Droid waiting game.

This release finally merges support for WatchX(Plus). Support for this watch has been contributed to "ksiwczynski", "mkusnierz" and finally "mamutcho", who also did the final polishing before official inclusion. We do not own the device ourselves, but we believe it works ;)

Thanks to a donation of a brand new ZeTime (THANK YOU!), I could finally test the state of ZeTime support and fix some long standing issues, plus add support for rejecting calls from the watch. There will be probably further fixes in the next release.

Gadgetbridge 0.43.0: Fossil Hybrid HR

Gadgetbridge 0.43.0 has been released and will be in F-Droid, god knows when. If she exists.

This release adds initial support for Fossil Hybrid HR. Again most of the work was contributed by Daniel Dakhno. Thanks Daniel! Unfortunately this device needs server side pairing with the official Fossil app once. The procedure we used to obtain the device specific secret key is complicated and described briefly in our wiki. There might be other easier methods by "cracking" the app but we refrained from trying. Please the wiki read before you decide this otherwise very nice device.

Gadgetbridge 0.42.0: iTag support

Gadgetbridge 0.42.0 has been released and is already build by F-Droid.

This release adds initial support support for "iTag" devices, contributed by Taavi Eomäe. Lacking any compatible devices, we cannot really tell you anything about it though ;)

Apart from iTag support, Taavi also contributed various other small fixes and improvements to this release. Thanks!

For user-facing changes since the last blog post, check the following list:

Version 0.42.0

• Initial iTag support
• Fix indefinitely lasting bluetooth scans when location permission has not been granted
• Try to stop incoming VoIP call notification when the call is answered
• Vectorize some icons and add a new Mi Scale 2 icon
• Mi Band 4: Make high MTU optional, fixes problems on some phones
• ZeTime: Fix probably broken support (duplicate id used by Fossil)
