Amazfish

Companion application for Huami Devices (such as Amazfit Bip, Cor, MiBand2/3 and GTS and GTS) and the Pinetime Infinitime

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

Supported Devices

There are 3 tiers of supported devices:

Gold

These are devices I have, have tested and will try not to break any functioanlity for an include:

  • Amazfit Bip
  • Amazfit GTS
  • Pinetime Infinitme
  • Bangle.js

Silver

These are devices which are properly implemented in the application, but I do not have and are tested by the commuity, and include:

  • Amazfit BipS
  • Amazfit Bip Lite I do not promise not to break funcaionality in these, but will fix where I can

Bronze

These are devices which use a protocol that is close to another suppored device, and so is treated like that device. Your mileage may vary with these devices.

  • MiBand 2/3/4
  • AMzfit Cor
  • Amazfit GTR

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 Zepp 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

Server Side Pairing Code

The newer devices (GTS, BipS etc) 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

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. If 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)

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.

Button Actions

Bip and GTS notify when the watch button is pressed. This is captured by amazfish which allows running actions on theses presses. An action can be ran on 2,3 or 4 presses. To confiure the actions, goto Settings > Application > Button Actions.

A custom script can be used, the script must be called harbour-amazfish-script.sh and be in the home folder. Example which sends a OTP code to the watch as a message:

#!/bin/sh
if [ "$1" == "4" ]; then
    CODE=`python3 -c 'import pyotp;totp = pyotp.TOTP("XXXX Authenticator code here XXXX");print(totp.now())'`
    dbus-send --session --print-reply --dest=uk.co.piggz.amazfish /application uk.co.piggz.amazfish.sendAlert string:'' string:'Google OTP' string:$CODE boolean:true
fi;
