First, my scenario is:
1- I use Sandbox v0.9.0; and Ubuntu 14.04.
2- Download GPIO demo code from Sanbox.
3- Install GPIO demo for Android.
4- I flashing application on the NodeMcu development board with ESP8266 WiFi module with a CP2102 converter.
All above step is OK.
But, My problem is:
1- When I open the GPIO control app on the Android when I press + button and enter the token (esp8266); But not any endpoint found.
2- I want to Know I need set Wi-Fi SSID and password for ESP8266 when I run build.sh deploy command?!
Because by default ESP8266 just have a name.
3- I try with both option (set ESP8266 Wi-Fi SSID and pass, and my Wi-Fi SSID and password), but not found endpoint on the GPIO control app
I found my answer.
Q: When I open the GPIO control app on the Android when I press + button and enter the token (esp8266); But not any endpoint found.
A: Because we need "Trustful" option, before flashing the application.
Follow the below steps:
Admin panel > Applications > GPIO control slave > Credential service > Trustful > Saved.
This solution works well.
