Since discovering my Android phone most likely doesn't support album art over AVRCP (even when setting the version to 1.6 in the developer options, weird), this is probably as far as the porting will go. I cannot find the service with the Cover Art UUID in my phone. You might continue developing it, though. It's in the source code, though. Maybe it's a Xiaomi thing. Might have to investigate further. Also consider moving to nOBEX
Python implementation of Bluetooth's Basic Imaging Profile for sending images between devices and includes the ability to resize, and convert images to make them suitable for the receiving device
Python3 porting and dependency upgrades by Gonzalo Ruiz @rgon January 2020. Tested on a Raspberry Pi 4 running: Raspbian GNU/Linux 10 (buster) Linux 5.4.83-v7l+.
This is a prototype implementation where some dummy data is used to make user experience easier. To make it to production grade, you need to tweak a little. Supports only linux platform as of now.
pybip3 requires Linux and python3 to run.
$ cd pybip3
$ ./requirements.sh # Install build dependencies (apt-get)
$ sudo python3 setup.py build
$ sudo python3 setup.py install
This python project is created to test the CoverArts feature of bluetooth's AVRCP 1.6 profile in CAR Infotainment system. Inorder to test that we primarily need 'bipserver' implementation, but we have implemented 'bipclient' as well to make development easier. This implementation is developed on top of pybluez and pyobex thanks to them!!
Make sure the setup have two bluetooth adapters since loopback support is not available in bluetooth, we cannot run both client and server in same hardware.

Start the server on one of the bluetooth address.
$ cd pybip3
$ python3 bipserver.py --address 00:1A:7D:DA:71:05
Starting server for 00:1A:7D:DA:71:05 on port 1
....
Start the client by specifying server's bluetooth address.
$ cd pybip3
$ python3 bipclient.py
