I am now using the UART-WIFI MODULE-TLG10UA03 to help me with my programming for arduino. I just want to get the db data of hot spots, so I used the command of "AT+WSCAN". But now I do not know what will be returned if I use Serial.read() command. Is the return value a string of just a character?
Another question is that can I use the Serial Monitor to monitor the data from the wifi module? Right now I cannot know what will be returned, so I cannot program to find a specific SSID that I want to know its db value. If I can know what I can get from the wifi module, the programming part would become much easier. If I cannot use the Serial Monitor, are there any other ways that I can use to know the value returned by Serial.read() command and the wifi module?

And you want us to do your research for you, with no links? No thanks.
