Arduino port version for ESP32 Compile Time setting vs. Runtime settings for IOT hub client and MQTT client

[hcr-mit]

Query/Question
Why does the ESP32 for Hub example work when the device id, device key and Azure IoT Hub URL are set in #define works correctly, but when set at runtime, does not connect?

Why is this not a Bug or a feature Request?
This is not a bug because the example works when ran per the instructions.

Setup (please complete the following information if applicable):

• OS: ESP32
• IDE: Arduino IDE
• Version of the Library used is current release of Arduino port of 1.5.0-beta.1

I am storing the device id, device key and Azure IoT Hub info in NVM on the ESP32S3 device. This is done during a provisioning session.
I have copied and pasted the example code that works, into a C++ class that retrieves the device and hub info and then sets the local variables at run-time before trying to execute the IoT Client and MQTT Client initializations. (no modifications to these functions).
I have set a 30 sec. delay between attempts to connect. Once the MQTT Client is started, I get the "Before Connect" event then I get the "Error" event with MQTT reporting "MQTT event MQTT_EVENT_ERRORE (39791) MQTT_CLIENT: MQTT connect failed".

The only modification from the example code was to declare the variables:
[
static const char *host;
static const char *mqtt_broker_uri;
static const char *device_id;
static const char *device_type;
]

Then run a function to set the values for these variables before initializing the clients (IoT , MQTT).
