Wi-Fi Provisioning

[mayank-mpc]

ESP-IDF Ver: v5.3.2
Devkit: ESP32 S3 N8R8

Requirements

• Trying to start the Wi-Fi provisioning again after getting Wi-Fi provisioning fail event

• It should be able to start provisioning everytime after receiving incorrect credentials, unavailability of Wi-Fi network

• It should be able to provision multiple times in runtime without restarting the device

At present it is working but after providing incorrect credentials 3 times the device reboots automatically stating the below logs. Also, there is a 30 second window provided to perform provisioning and the timer will stopped once the device is connected with the mobile device for provisioning.

Code: Select all

assert failed: insert_free_block tlsf.c:358 (current && "free list cannot have a null entry")
HINT: CORRUPT HEAP: heap metadata corrupted resulting in TLSF malfunction.
Make sure you are not making out of bound writing on the memory you allocate in your application.
Make sure you are not writing on freed memory.

My handler code

Code: Select all

case WIFI_PROV_FAILED_EVENT:
                        ESP_LOGE(CONN_MNGR_TAG, "Provisioning failed");
                        if(wifi_prov_check_for_provisioning_enabled())
                        {
                            ESP_LOGI(CONN_MNGR_TAG, "Provisioning is enabled");
                            wifi_prov_stop_provisioning(); // wifi_prov_check_for_provisioning_enabled is assigned with false in this function
                            vTaskDelay(1000 / portTICK_PERIOD_MS);
                        }
                        if(ESP_OK != wifi_prov_start_provisioning()) // wifi_prov_check_for_provisioning_enabled is assigned with true in this function
                        {
                            ESP_LOGE(CONN_MNGR_TAG,"Error in wifi_prov_start_provisioning()");
                        }
                        wifi_prov_start_provisioning_timer();
                        break;

Fixes applied by me for resolving these problem

• Calling Wi-Fi provisioning stop function everytime before Wi-Fi provisioning start function also added a delay of 1 sec to allow safe release of release before starting provisioning service again

• Increased stack of the task handling these process from 4 kb to 8kb

• Used wifi_prov_mgr_reset_sm_state_on_failure() function for reprovisioning purpose but still getting the same error

• Verified use of stop provisioning function twice in row

Please suggest a way to perform provsioning again and again without rebooting the device again
