A setting/proto for the device hotspot to be hidden (hidden ssid, stop broadcasting ssid/respond to probe requests), with this the only way to connect to the hotspot is to enter it's name (and password?) manually either by knowing the mac address or by reading the AP name on the screen
It's an IoT DIY project which notifies you when you have received a parcel or a letter in your letterbox. This project uses an HelTec AB01 LoRaWAN module to send data over an LoRaWAN Gateway when WiFi is out of range. I use an Helium Gateway from the People's Network in order to forward packets over Helium Network which send data to AWS IoT Core (MQTT) or Pipedream (HTTP) and more. LoRaWAN is a bidirectional protocol useful when you need to send few data over long distance from low-power and low-bandwidth IoT.
