BT: bta_gattc_co_cache_addr_init, Line = 333, nvs flash get blob data fail, err_code = 110c

Hi I am getting a BT error.
First I initialize wifi, second mqtt client, and then the bluetooth in order to read an itag's ble address and send that address to a mqtt broker. However after initializing the mqtt client I got this message:

Re: GATT Client + Simple WiFi Examples

I think youve made a good find here. If we look on the v3.0 code base we find:

https://github.com/espressif/esp-idf/blob/release/v3.0/components/bt/bluedroid/include/bt_trace.h

Re: ESP32 reads BLE iTag's Battery Service

Thanks! I was able to read the value:

Code: Select all

const char *char_pointer = (char*)p_data->read.value
int battery_percentage = (int)*char_pointer;
ESP_LOGI(GATTC_TAG, "(p_data->read.value) Battery level: %d %%",battery_percentage);
