Neewer Lights are RGB LED panels supposed to be controled with a Neewer App on your mobile phone (iOS / Android). The official App connects to the devices with Bluetooth Low Energy (BLE) and allows the user to change the color, mode, luminosity, play a specific program, etc.
We wanted to be able to use those panels in an audio/midi reactive setup for visual perfomances, triggered by MIDI events or audio in real time (from Touchdesigner or any other visual software). We analyzed the BLE messages and implemented a small server to reproduce the app behavior and send our own messages to the device.
Connects to a Neewer RGB Light using its mac address. Listens to incoming UDP messages and forward them to the light panel with BLE. You can produce the UDP messages from Touchdesigner ask the light to change it's color or luminosity in real time.
git clone https://github.com/null-part/neewerserver.git
cd neewerserver
pip install --user -r requirements.txt
usage: neewerserver.py [-h] [-a UDP_LISTEN_ADDR] [-p UDP_LISTEN_PORT] [-l] [-c COMMAND] -m MAC_ADDRESS
optional arguments:
-h, --help show this help message and exit
-a UDP_LISTEN_ADDR, --udp_listen_addr UDP_LISTEN_ADDR
Address to use for the UDP server. Default: 0.0.0.0
-p UDP_LISTEN_PORT, --udp_listen_port UDP_LISTEN_PORT
Port to use for the UDP server Default: 1664
-l, --list_commands List available commands
-c COMMAND, --command COMMAND
Command to execute. Available commands: scan, serve (default: serve)
-m MAC_ADDRESS, --mac_address MAC_ADDRESS
Device mac address. Must be set.
You can detect the BLE handle to use thanks to the scan command
Example:
./neewerserver.py -m 'DD:9D:97:26:40:00' -c scan
./neewerserver.py -m 'DD:9D:97:26:40:00'
This is an expimental project. Use at your own risk.
The server may disconnect from the light after some time, you may want to restart the server to reassociate to the device.
BLE latency is quite acceptable. If you experience packet drop, try to get closer to your light panel. We also had some issues with a mobile client connected as the same time as neewerserver.
