Already fix it guys, thanks anyway
I've tried to connect an Xbee Wifi S6B smt module (FW 2021) to different commercial routers using WPS but it seems it doesn't work.
After sending the atcb2 command, I push the WPS router's button, but nothing happens, the Associated LED keeps permanently on. Sometimes atai receives 0x02 or 0x23.
If I configure the module with the modem's SSID and password, the connection is ok. Active scan also reads all the networks around.
