AMBEServer3003_darwin_arm64                macOS Apple Silicon


Use the following config.ini file

[SERIAL]
comport=/dev/ttyUSB0
[AMBEServer]
UDPPort1=2460
UDPPort2=2461
UDPPort3=2462
[LOG]
debug=0
logfile=AMBEServer3003.log

The default buffering on a Raspberry Pi is too large. You should reduce it; otherwise, you may experience significant audio jitter and interruptions. Many thanks to SA7CHI for identifying this issue.

echo 'ACTION=="add", SUBSYSTEM=="usb-serial", DRIVER=="ftdi_sio", ATTR{latency_timer}="1"' | sudo tee /etc/udev/rules.d/99-ftdi-latency.rules > /dev/null
sudo udevadm control --reload-rules && sudo udevadm trigger
sudo udevadm trigger --action=add /sys/bus/usb-serial/devices/ttyUSB0

Check: 
cat /sys/bus/usb-serial/devices/ttyUSB0/latency_timer
Response must be: 1
