Amazfish

Companion application for the Huami Amazfit Bip and Cor

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://github.com/Freeyourgadget/Gadgetbridge/wiki/Amazfit-Bip-Firmware...

App has been tested using an amazfit bip, downloading the latest (0.1.1.45) official firmware.

The firmware is split into multiple files on these devices.  With the official MiFit app, all are downloaded at once, and everything works fine.  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.*.  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 resource (.res).  If you 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 resource sent.  Just wait for the app to connect again, then send the resource.  It may work better to send the resource first, then the firmware.

The following types of file exist:

firmware, resource, a-gps data, fonts

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.  Official devices unknown.

Implemented

• Pairingfrom
• Notifications
• Calls
• Some settings
• Retrieving activities
• Heartrate Chart
• Alarms
• Watchface download
• Firmware upload
• Activity Sync

Todo

• More Settings
• Weather
• 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.
