switching from ble to wifi (IDFGH-4365)

[lky2431]

Hi,

I am writing a project using ESP32-WROVER. One of the feature is that i have to send a wifi and password from a mobile phone to the esp32 through ble gatt server. The wifi information is sucessfully received. However, there is "lock_acquire_generic" bug or sometimes "corrode heap" bug when the esp is setting the wifi information.

The code I use to receive the wifi information like: static void gatts_profile_event_handler(esp_gatts_cb_event_t event, esp_gatt_if_t gatts_if, esp_ble_gatts_cb_param_t *param) {..... }else if (res == SPP_IDX_SPP_WIFI_VAL){ ESP_LOGI(GATTS_TABLE_TAG,"message come"); ..... sta_on();

The code I use to switch to wifi like: void sta_on(){ ESP_ERROR_CHECK(esp_wifi_set_config(ESP_IF_WIFI_STA, &wifi_config) ); ESP_ERROR_CHECK(esp_wifi_start() ); } The wifi is already initialized and set to STA before. It work completely fine if I set using wifi but not bluetooth for first program. After sending the wifi information. I see the log below: 0x40084e86: lock_acquire_generic at C:/esp/components/newlib/locks.c:143

0x401604e0: esp_wifi_set_config at ??:?

If seemed the problem is that the program cannot locate proper memory when I set the esp_wifi_config.

If anyone have similar experience on how to solve this, could you share some to me. I would be grateful about it. Thank you

@lky2431 Could you please provide a demo to reproduce the issue? You can also try the blufi example in IDF. It does the same thing as you expected.

@lky2431 It looks like a heap issue，there are several heap issues fixed，please update the latest release version
