Hardware Setup

1

Install Wi-Fi Module

Insert the NFA765A module into the M.2 slot at a 30-degree angle, press flat, and secure with the provided screw.
2

Connect Antennas

  • ANT0 (2.4G) — shared between Wi-Fi and Bluetooth
  • ANT1 (5G/6G) — Wi-Fi 5 GHz and 6 GHz only
3

Connect UART Debug Cable

Connect the UART cable to the debug port and note the assigned COM port or /dev/ttyUSB device.
4

Connect Power and Boot

Power on and observe the boot sequence via UART console. Default login: ubuntu / ubuntu.

Verify Components

​
Wi-Fi

lsmod | grep ath11k
iw dev
ls -la /lib/firmware/ath11k/

​
Bluetooth

sudo lsmod | grep bt
hciconfig
ls -la /lib/firmware/qca/
systemctl status bluetooth

​
Wi-Fi Configuration

​
Station Mode

nmcli dev wifi list
nmcli dev wifi connect <SSID> password <password>
nmcli general status
ifconfig wlp1s0
ping 8.8.8.8

​
Set MAC Address (Optional)

The manually set MAC address persists only until the next reboot, then reverts to the factory OTP address.
ifconfig wlp1s0 down
ifconfig wlp1s0 hw ether XX:XX:XX:XX:XX:XX
ifconfig wlp1s0 up

​
Hotspot Mode

1

Add SoftAP interface

iw dev wlp1s0 interface add wlp1s0 type managed
2

Configure and start hostapd

hostapd -B /etc/hostapd.conf
3

Start DHCP server

brctl addbr br0
brctl addif br0 wlp1s0
ifconfig br0 192.168.225.1 netmask 255.255.255.0 up
dnsmasq --conf-file=/etc/dnsmasq.conf \
  --dhcp-range=br0,192.168.225.20,192.168.225.60,255.255.255.0,43200
Stop hotspot: 
killall hostapd
ifconfig wlp1s0 down
rm -rf /var/run/hostapd/wlp1s0

​
Bluetooth Configuration

​
Set Bluetooth MAC Address (Optional)

A manually set Bluetooth MAC address does not persist across reboots.

Debugging

# Wi-Fi
echo "module ath11k +p" > /sys/kernel/debug/dynamic_debug/control
dmesg > /tmp/dmesg.txt

# Bluetooth
echo "module bluetooth +p" > /sys/kernel/debug/dynamic_debug/control
echo "module btqca +p" > /sys/kernel/debug/dynamic_debug/control
dmesg > /tmp/bt_dmesg.txt

​
Troubleshooting

dmesg | grep ath11k
ls /lib/firmware/ath11k/
Verify SSID and password; check AP security settings.
dmesg | grep -i bluetooth
ls /lib/firmware/qca/
Ensure both devices confirm the same passkey; retry pairing.
A2DP and HFP require WCN6750/WCN6856 — verify profile support.
