Like @cramer has said, you need a special tools from globalsat, LoraConfig_S-0PC-31-1611091, this tool allows to filter the information received from the device and allow the use of AT commands, and then you can use another tool they provide or a serial terminal, in my case I'm using realtek to send AT commands to the device.
With the commands i have configured the otaa join Mode and has made a join against a multitech conduit, that is the only test i have made.
One question for those of you who have the device, have you been able to use the commands with the DEV prefix? I don't receive any response when i use them.
On another note, i have been unable to read the configuration from the device with the configuration tool, so i haven't tried to change that configuration.
