[[file:src/ada.cpp][Arduino source (adafruit on ESP32S2)]] Arduino code that reads linear acceleration, sensor fused quaternion orientation data and the battery voltage on an ESP32S3 connected to an Adafruit BNO055 orientation sensor.
NOTE: you have to set the sensor ID via source! And the receiver's mac address. Linux monitor mode can receive packages pointed to other mac addresses though.

This may be simpler since it doesn't depend on the wifi card used, but the max rate seems to be about 160 packets per second.
*** Linux receiver
You need a wifi card that supports monitor mode for this.
Two scripts are provided to turn monitor mode on/off; [[file:linux-receiver/monitor_on.sh][monitor_on.sh]] and [[file:linux-receiver/monitor_off.sh][monitor_off.sh]]. Run the receiver with [[file:linux-receiver/pozeni.sh][pozeni.sh]], the receiver's code in C can be found in [[file:linux-receiver/main.c][main.c]].
This way, around 700-800 packets can be received in a second. Also OSC packages are sent directly to supercollider, bypassing the SLIP decoder.

Library for decoding SLIP encoded OSC data via serial USB directly into supercollider.
