Answers checklist.

• I have read the Rainmaker documentation and the issue is not addressed there.
• I have updated my IDF branch (release/vX.Y) to the latest version and checked that the issue is present there. This is not applicable if you are using Rainmaker with Arduino.
• I have searched the Rainmaker forum and issue tracker for a similar issue and not found a similar issue.

IDF / ESP32-Arduino version.

Operating System used.

What is the expected behavior?

Calling esp_rmaker_stop(), followed by esp_rmaker_node_deinit() stops any rainmaker processes from running.

What is the actual behavior?

Calling esp_rmaker_stop(), followed by esp_rmaker_node_deinit(), and then attempting to run esp_rmaker_node_init() results in the following error message.

 esp_rmaker_core: ESP RainMaker is still running. Please stop it first.

This is particularly frustrating as all our production code is guarded behind a strict set of unit tests. If it's impossible to teardown and deinit rainmaker, then we can't run tests on it, which leaves our production code exposed to bugs.

Steps to reproduce.

esp_rmaker_node_t *node = NULL;

bool Rainmaker_Init(const char *node_name, const char *node_type)
{
    ESP_LOGD(TAG, "Rainmaker init");
    esp_rmaker_config_t rainmaker_cfg = {
        .enable_time_sync = true,
    };
    node = esp_rmaker_node_init(&rainmaker_cfg, node_name, node_type);
    if (!node)
    {
        ESP_LOGE(TAG, "Could not initialise node");
        return false;
    }

    esp_rmaker_timezone_service_enable();

    return true;
}

void Rainmaker_Deinit(void)
{
    ESP_LOGD(TAG, "Rainmaker deinit");
    esp_rmaker_stop();

    app_insights_disable();
    esp_rmaker_node_deinit(node);
    node = NULL;
}


TEST_CASE("Rainmaker teardown success", "[rainmaker]")
{
    Rainmaker_Init("Test-node", "Test type");
    vTaskDelay(pdMS_TO_TICKS(1000);
    Rainmaker_Deinit();
    vTaskDelay(pdMS_TO_TICKS(1000);
    Rainmaker_Init("Test-node", "Test type");
}
