- Wed Jun 17, 2015 5:58 am #20681 Hello, I am trying to add smartconfig to esp_mqtt project by tuanpm - http://tuanpm.net/native-mqtt-client-li ... r-esp8266/

For smartconfig, I have used and tested it. I used app from this github repository IOT-Espressif-Android and use espressif iot SDK v1.1.1. They work perfectly.

Unfortunately, adding any code from esp_mqtt cause the firmware to not working anymore. I am still looking on how to use smartconfig and esp_mqtt together. I attached my code:

}



Here is my correct smartconfig output:


And this is what happen when I add esp_mqtt code:


Now, I think this is because in the SDK docs, it states that smartconfig_start must run alone, we cannot run other code with it. My question is, how can I run other function in ESP8266 after smartconfig finished?
