esp8266 hangs at second wifisecure connection
Posted: Sun Jun 17, 2018 10:29 amHello,
I'm having issues with my project. I'm trying to connect to different websites to get json results. First connection (getInfo("crypto")) goes well, but esp8266 hangs on second connection (getInfo("weather_today")).
If I put "weather_today" in first position, it runs well and hangs on second connection too...
Thanks for any help !
