Unable to Compile Thermostat Example for ESP 32

[samisarfraz]

I am trying to compile the code and getting error:

I also cannot add library to Arduino IDE and get an error:

Arduino: 1.8.5 (Windows 7), Board: "ESP32 Dev Module, Default, QIO, 80MHz, 4MB (32Mb), 921600, None"

Dear @0x1abin ,

I have 1st used your recommended library by VSChina but unfortunately all the people who are using this library are getting same issue of ESP 32 device rebooting and not making stable connection with Azure IoT Hub. it gets connected but after sometime it gets TLSIO / MQTT error SNTP and nobody is responding to resolve listed below error.

I have noticed one amazing things that when i have used example of remote monitoring using DHT 22 temperature & humidity sensor, it works fine and makes a very stable connection with Azure Iot Hub and device doesn't reboot and i have kept your example running for more than 6 hours and noticed zero error but in your example their is no support of receiving messages from Azure iot hub to device so we can execute functions but if use azure iot hub to send message to device then i see on serial monitor on device an error rather a message (but it receives at device end but doesn't comprehend)

I feel their is very minor work need to be done to your recommended library of VSChia but unluckily their is no support to resolve.

_An error occurs in the two examples if the delay between messages of 5 minutes or more.

Hope hear from you with some positive outcome :)

Solving this problem is difficult for me, maybe you can try the IDF stable SDK.

closing because the date, can open again if the issue still exists, seems to be solved.
