Amazfish

Companion application for the Huami Amazfit Bip, Cor, MiBand2/3 and GTS

Requires sailfish version 3.0.3.8 or above due to changes in the base sailfish image

Powered by KEXI

As of version 0.5.1, actiivity data is retrieved into an sqlite database. Becuase I think it is important to allow individuals to be in control of their own data, and that they should have the ability to analyse it themsleves, I have chosen to store data in a KEXI compatible database. This will allow you to copy the database from the phone, and open it up inside KEXI on Linux/Windows/Mac and perform queries and reports on it. This added ability means i link to a couple of KDE libraries, which should be installed automatically.

Firmware Download - READ FIRST - I am not liable if you brick your watch ;)

Read this for info about which files to flash https://codeberg.org/Freeyourgadget/Gadgetbridge/wiki/Amazfit-Bip

File download has been tested using an Amazfit Bip and GTS.

The firmware is split into multiple files on these devices. With the official MiFit app, all are downloaded automatically in the correct oder. With this app, you have to send each file individually. The firmwares are available by extracting the MiFit apk, and looking in the assets/ folder for files named Mili_chaohu.* for the Bip. GTS firmware files can be found online, the device name is kestrelw, but be sure the files your arw downloadling are legitimate. When you select a file, its type and version will be determined, and you will be prevented from sending invalid files.

The firmware (.fw) requires a matching font (.ft) and resource (.res). Send the firmware first, the app will send a reboot command at the end of the transfer, and the watch will boot up into a mode where it needs the matching font and resource sent. Just wait for the app to connect again, then send the font and resource.

The following types of file exist:

firmware, resource, a-gps data, fonts

So, to re-iterate, the firmware flashing order is:

.fw
.ft
.res

Amazfit GTS

GTS requires a server-side pairing key which requires inital pairing with an android device. To get the key, follow the instructions here and enter into Amzafish when prompted, WITHOUT 0x at the beginning.

See https://codeberg.org/Freeyourgadget/Gadgetbridge/wiki/Amazfit-GTS

MiBand 2/3/Cor

These devices are untested and use the Bip backend. Should be safe to try and FW download should not be allowed.

Pairing Issues

Pairing works for myself, sometimes I have to try twice. If pairing doesnt work at all, then try:

keep the app open, and pair again in the BT settings page of sailfish
in the sailfish BT settings page, delete all entries and try again
turn off/on BT on the phone
factory reset the watch

Check if after all this, pairing works from the sailfish BT settings page. It should pair and connect just fine from there. f that doesnt work, my app wont either.

Not all features currently implemented

May not work on all devices

Uses Bluetooth Low Energy to communicate with the watch, this is known to be problematic on some devices. it is known to work on the Xiaomi Mido. Probably also works on the FP2 and is tested ont he XA2.

Implemented

Pairing
Notifications
Calls
Some settings
Retrieving activities
Heartrate Chart
Alarms
Watchface download
Firmware upload
Activity Sync
Basic music control

Todo

More Settings
Support other devices (maybe eg MiBand2, as it is similar)

The Cor is also claimed to be working, but as i dont have that device, i cant test it.

Tip: On your device, create a symlink in /home/nemo to /home/nemo/.local/share/harbour-amazfish This way, you can easilty copy the database off the phone using MTP.

The rockpool devs, as i borrowed the call handling code handling code from them
The gadgetbridge devs, which gave me a lot of hints and inspiration from their device code.
