Why is my ESP8266 MQTT Client Gateway an Access Point?



  • About 3 weeks ago I setup the ESP8266 MQTT Gateway from the Development branch and with the exception of adding the WiFI information and using a static IP I didn't change anything else. Everything worked as is and I am quite happy with it and thought nothing of it. this past weekend I got a new phone and had to join it to my router. In doing so I saw a wifi network called ESP_09E3. It turns out it is the Gateway advertising as a wifi access point, unprotected and open for all. I was quite worried but it was not a big problem. It has an IP that is not in my internal subnet and non routable ... but still ... why is it advertising as an AP and how can I stop it?

    Thank you,

    Mike

  • @hek I added the line to the file mentioned and uploaded my sketch again but it did not change anything.

    Any other ideas?

    Thank you,

    Mike



  • Forget that last message. I reliazed you mentioned to change the MyGatewayTransportEthernet.cpp, which I did, but I'm running the MQTT Gateway. I found the same location in the MyGatewayTransportMQTTClient.cpp file (line 157) and added the entry there. That disabled the AP advertisement.

    Thank you,

    Mike

    You can add it in the setup of the gateway code, works fine for me...

    WiFi.mode (WIFI_STA); // turn off AP mode

    Also, a note: In my testing of a ESP8266 and a RFM69HW radio at 915MHZ, I noticed that i no longer had any range, 100 ft max. Using the same radio on a serial gateway, my range was over 1000ft.. I suspect that the WiFi radio was desensitizing the RFM69 radio receiver... So be cautious! and do some testing.

    Thank you, I will try it right in the gateway code.

    I'm using the NRF24L01+ radios and I have not seen any noticeable difference in the range. Mind you I never tried to see how far I can go when I was using a serial gateway, but for now all my sensors work as they did with the serial gateway.
