3. Select it and check the box to enable MQTT discovery if desired, and hit submit.

Add P1Reader to wifi and MQTT

1. When your P1Reader starts up, it sets it up in Station mode and tries to connect to a previously saved Access Point.
2. if this is unsuccessful (or no previous network saved) it moves the P1Reader into Access Point mode and spins up a DNS and WebServer (default ip 192.168.4.1).
3. using any wifi enabled device with a browser (computer, phone, tablet) connect to the newly created Access Point.
4. because of the Captive Portal and the DNS server you will either get a 'Join to network' type of popup or get any domain you try to access redirected to the configuration portal.
5. choose one of the access points scanned, enter password also add the user we made in Mosquitto broker then click save.
6. P1Reader will try to connect. If successful, it relinquishes control back to your app. If not, reconnect to AP and reconfigure.
7. To reset wifi config on the P1Reader and set it back to Access Point double press the the reset button on the P1Reader.
