Bluetooth causing board to crash

[nzjeux26]

Hi, Since I was having real issues with my SPIFFS i thought i'd park it for today and try to get Bluetooth working so I can use it as input. But yet again I've been met with errors and cannot get past them.

I followed through the GATTS_Server tutorial in GitHub, everything compiles fine and looks good, except when i load it to the board it crashes with the following:

Core 0 register dump:

Now after some searching, i *think* it's trying to access a memory point it's not allowed to, so i found a stack decoder on github but all i get is:

0x401398b1: __assert_func at /builds/idf/crosstool-NG/.build/HOST-x86_64-w64-mingw32/xtensa-esp32-elf/src/newlib/newlib/libc/stdlib/assert.c:58

This means nothing to me so I thought I would just start removing things until it doesn't happen, as it turns out it would keep happening until I took everything out!

Here is my code:

Code: Select all

// Initialize NVS
    esp_err_t err;
    err = nvs_flash_init();
    if (err == ESP_ERR_NVS_NO_FREE_PAGES || err == ESP_ERR_NVS_NEW_VERSION_FOUND) {
        ESP_ERROR_CHECK(nvs_flash_erase());
        err = nvs_flash_init();
    }
    ESP_ERROR_CHECK( err );

    esp_bt_controller_config_t bt_cfg = BT_CONTROLLER_INIT_CONFIG_DEFAULT();
    err = esp_bt_controller_init(&bt_cfg);
        if(err){
        printf("%s initialize controller failed\n", __func__);
        //ESP_LOGE(GATTS_TABLE_TAG, "%s enable controller failed\n", __func__);
        return;
    }

I have the rest in comments further down, but even just the above is enough to cause the crash.
Here are the includes i am using:

Code: Select all

#include <driver/gpio.h>
#include <esp_system.h>
#include <freertos/FreeRTOS.h>
#include <freertos/event_groups.h>
#include <freertos/task.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <math.h>
#include <esp_log.h>
#include <esp_sntp.h>
#include <nvs_flash.h>
#include "fonts.h"
#include "graphics.h"
#include "demos.h"
#include "graphics3d.h"
#include "input_output.h"

//#include "blue.h"
#include "esp_bt.h"
#include "esp_gap_ble_api.h"
//#include "bta_api.h"
#include "esp_gap_ble_api.h"
#include "esp_gatts_api.h"
#include "esp_bt_defs.h"
#include "esp_bt_main.h"
#include "esp_gatt_common_api.h"
#include "sdkconfig.h"
#include "esp_debug_helpers.h"

I have commented out BTA_api.h because even with a manual entry i cannot get VSCode to read it, I get
"cannot open source file "common/bt_target.h" (dependency of "bta_api.h")"

This is weird because all the Bluetooth headers are in the same file path. I don't think missed the BTA_API.h is enough to cause all my woes but it wouldn't surprise me.
**EDIT**

So as a test i also did the BLE Beacon example in the book Developing IoT Projects with ESP32, and it too caused the same result as above. So it's definitely something in the Bluetooth header files or something that is causing this.

Cheers
