Wireless Serial Communication with Arduino? Problems with HM10


greetings,

i first time poster apologize if in wrong place tried fit thought should go.  trying create wireless solution arduino. want set com port still windows computer software wrote work same if plugged in via usb.

what have tried far:
i bought hm-10 module , connected power 3.3v, gnd gnd, , tx / rx pins pins 3 , 4 on arduino (not 0 , 1 because used when connects via usb). used sample sketch "softwareserial" changing serial pins mine.

when use softwareserial, can send @ command without problem. @ responds ok, , others appropriately should. seems working fine level.  problem have setting com port. under windows 7 / 10 (i have tried both), can connect through usb bluetooth module. hm-10 says "connected" , displays under device manager.

as many many sites suggest, next step goto more bluetooth options,  com ports > add com port. there supposed click outgoing (your pc initiates connection) , under dropdown pick hm-10 list. problem nothing appears in list me!  missing obvious? have change on hm-10?  missing piece of hardware? have hm-10 , arduino uno. appreciated have spent weeks trying figure out.

thanks ahead of time,
eric
