Gateway OS WiFi access point

Hi all,
I’m successfully using the LoRa gateway OS on a Raspberry Pi 3. Before I dive into editing the Yocto recipes, I would like to know if anyone has already tried setting up a WiFi access point, something like: ‘gateway-’ with mac address retrieved like

MAC_ADDRESS=$( sed -n 's/^.*"gateway_ID": "\([^"]*\)",*$/\1/p' /etc/lora-packet-forwarder/global_conf.json )

and pointing requests to e.g. http://localhost:8080. It seems I will need hostapd, but perhaps there’s something build-in already which I don’t know. Any tip is much appreciated!
