Unable to Establish HTTPS Connection on Non-Tuya Server Using TuyaOS SDK

Issue Title:

Unable to Establish HTTPS Connection on Non-Tuya Server Using TuyaOS SDK

Issue Description:

I'm encountering difficulties establishing an HTTPS connection to a non-Tuya server using the TuyaOS SDK. Below are the relevant logs from my application:

[01-01 00:00:05 ty E][custom_http_client.c:321] Error opening HTTP session.(code: -1)

Steps to Reproduce:

1. Attempt to establish an HTTPS connection to a non-Tuya server using the TuyaOS SDK.
2. Observe the logs provided above.

Expected Behavior:

The HTTPS connection should be successfully established without errors.

Actual Behavior:

The connection attempt fails with the following error: Error opening HTTP session.(code: -1).

Environment Details:

• TuyaOS SDK version: [3.9.0]
• Device/Platform: [Beken7231n]
• Server URL: [REDACTED_URL]

Additional Information:

• I have confirmed that the server is reachable and operational as I have tested with python server.
• I have verified the correctness of the server URL.

tuya_tls_config_t tls_config;
tls_config.mode = TUYA_TLS_SERVER_CERT_MODE;  // Example mode, adjust as needed
tls_config.hostname = host_uri;
tls_config.port = 7000;  // HTTPS port

// Set CA certificate (assuming CA_CERT is defined as per your previous definitions)
tls_config.ca_cert = CA_CERT;
tls_config.ca_cert_size = strlen(CA_CERT);

// Set timeout and other parameters as needed
tls_config.timeout = 10;  // Example timeout

// If you have client certificate and key, set them as follows:
tls_config.client_pkey = SSL_PRIVATE_KEY;
tls_config.client_pkey_size = strlen(SSL_PRIVATE_KEY);

/* Setup callbacks */
tls_config.f_send = send_callback;
tls_config.f_recv = recv_callback;
tls_config.exception_cb = event_callback;

// Open HTTP session with Tuya TLS configuration
int http_ret = http_open_session_with_config(&https_handle, host_uri, &tls_config, TLS_ENABLE, 0);

Proposed Solution:

Please investigate the logs provided and advise on any configuration changes or updates to the TuyaOS SDK that may be required to establish HTTPS connections to non-Tuya servers successfully and also explain what error this line is referring to specifically L->0 and M->0:

[01-01 00:00:05 ty E][lr:0x5b511] MAX SECURITY_LEVEL CONFIG ERROR: L->0,M->1
[01-01 00:00:05 ty E][lr:0x84847] tls transporter connect err:-2

how to connect bk7231 to my server

How can i connect BK7231 to my server? i found function "create_mqtt_hand" in mqtt_client.h in SDK folder but i could not find anywhere your examples call this function.
