Connection
WhenyourdevicefirstestablishestheserialconnectiontotheWM18x,youshouldwaitforthe
NTX_RESTARTmessagebeforesendinganythingtothemodule.NTX_RESTARTindicatesthatthe
moduleiscommunicatingwithyourdeviceproperly.
Next,waitfortheNTX_STATUSmessage.Thismessagewillindicateifthemoduleiscommunicatingwith

theAPandwithLet’sCook.
Ifyourdevicetakeslongertocomeupandstartcommunicatingseriallyandthismessageismissed,itis
suggestedthatyoumakecallstoNTX_ONLINE
FromtheresultsoftheNTX_STATUSorNTX_ONLINEmessage,youshouldbeabletodecidewhattodo
next.
SincetheWM18xconnectstothelastknownaccesspointautomatically,aftertheinitialconnectionis
establishedthereisverylittleforthedevicetodoonstartupaftertheinitialconnectionisestablished.
Inmostsystems,thereisaUItosettheSSIDandpassword.Initiallyyoushould
callNTX_CONFIGsoyou
canshowtheMACaddressintheUI.ThisisimportantbecausetheMACaddressisusedtouniquely
identifythemoduletotheNetworkcloud.Yourdevice’sserialnumbermaychangebuttheMACwillnot
changesoitcanalwaysbeusedtofind
thedeviceifyouareunsureoftheserialnumber.
Whenadeviceconnectsforthefirsttime,weatherafterapowercycleorwhenthemodulestatus
transitionsfromofflinetoonline,itisrecommendedthatthedevice,getthecurrenttimeanddateand
thensendthecurrentstatus
(NTX_LC_STATUS)andmetadata(NTX_LC_META_DEVICE).Thismakessure
CustomerConnecthaseverythingitneedstoshowthecurrentstatusofthedevice.
Afterconnectiontotheaccesspointissuccessful,themoduleisreadytoconnecttotheNetwork
system.Tostartthisprocessitneedstheserialnumberof
thedevice.Use
NTX_SET_DEVICESERIAL,{serialnumber}tosetit.
