I want to make a characteristic that returns long data from the log buffer. I wrote such a callback

#define LOG_RING_BUFFER_SIZE 2048
void create_logs_dump(uint8_t* buffer);

static uint8_t log_buffer[LOG_RING_BUFFER_SIZE];

int log_gatt_chr_access_cb(uint16_t conn_handle,
uint16_t attr_handle ...
