CanSDO getValue assumes next message is the response.

double GetValue(String name) {
    if (state != IDLE) return 0;
 
    twai_message_t rxframe;
  
    int id = getId(name);
  
    requestSdoElement(SDO_INDEX_PARAM_UID | (id >> 8), id & 0xFF);
  
    if (twai_receive(&rxframe, pdMS_TO_TICKS(10)) == ESP_OK) {
      if (rxframe.data[0] == 0x80)
        return 0;
      else
        return ((double)*(uint32_t*)&rxframe.data[4]) / 32;
    }
    else {
      return 0;
    }
}

It doesn't check the ID of the received can message is an SDO response, if it's a response for the requested parameter ID etc
