O got 5 of these, have somefar tested 3 of them with several different libraries, and two different ESP8266 boards, using the 5 v as supply voltage. Only led I get on is the green PWR led on back of the module. In case there is something extraordinary that needs to be done in order to get these working, that should be mentioned in the page, and if not, then I suppose the modules I got are non-functional
