Dear Flavio
In the free version of Ruhavik you can use Setbox to send commands to the tracker. For this it is necessary:
- know the exact syntax of the GPSR command (we recommend checking directly with the manufacturer, he is the one who has the most accurate information);
- that the tracker and additional equipment are correctly connected to the equipment;
- the tracker was in touch.
In addition, if your tracker is a copy (clone) of a Concox, Coban or Xexun tracker, then if you connect it using one of these types of device, then most likely you will also have a this button that is preconfigured for these trackers.
