        Hi @Mennyt , if you are looking for a cheap one then NK STAR USB 2.0 Mini Microphone will do the job well, or if you need better audio and special Audio processing algorithms includes VAD, DOA, Beamforming, NS, AEC and KWS you try the Seeed Studio ReSpeaker, also keep in mind normally USB Webcam has the built-in MIC and you can also utilize that too.

        All the best with your project, Happy making.

        • @rafitc99 said in NMCLI AP Mode config error | Connection activation failed: No suitable device found for this connection | Raspberry Pi 3 Model B Rev 1.2:

          host="MyRPiAPMode"
          sudo nmcli con add type wifi ifname wlan0 con-name $host autoconnect yes ssid $host
          sudo nmcli con modify $host 802-11-wireless.mode ap 802-11-wireless.band bg ipv4.method shared

          sudo nmcli con modify $host wifi-sec.psk "SomeRandomPassword"
          sudo nmcli radio wifi on
          sudo nmcli con up $host

          Hi @rafitc99, Are you able to set up the AP when trying the commands individually?

        • I was trying to configure AP mode in Raspberrypi by using Network Manager. I'm using the below script. but it is throwing some errors.

          Bash Script to set AP Mode

          host="MyRPiAPMode" sudo nmcli con add type wifi ifname wlan0 con-name $host autoconnect yes ssid $host sudo nmcli con modify $host 802-11-wireless.mode ap 802-11-wireless.band bg ipv4.method shared sudo nmcli con modify $host wifi-sec.key-mgmt wpa-psk sudo nmcli con modify $host wifi-sec.psk "SomeRandomPassword" sudo nmcli radio wifi on sudo nmcli con up $host

          Error ----

          Connection 'MyRPiAPMode' (60965f2a-f510-48ef-afaf-0864242d0c06) successfully added. Error: Connection activation failed: No suitable device found for this connection (device eth0 not available because profile is not compatible with device (mismatching interface name)).

          nmcli con (After script execution)

          I tried to make it availble via sudo nmcli radio wifi on
          But not working.
