connect HLK-RM04 to arduino uno (or mega)
when went reply existing thread "the system" suggested start new thread 1 on 120 days without response. trying accomplish:
getting rm04 send email on wifi on trigger event arduino card.
i person can't seem rm04 respond in way examples in chunlinhan/wifirm04 library. i have read every post on forum concerning , many others. got stopped @ "serial1" error.
i have used code below rayshobby.net (thanks ray). , have been able talk rm04 , in post. maybe else.
my objective not chunlinhan library work (but thank great work), rm04 send email on wifi via trigger event on arduino card. don't care route take.
ideally want work pro-mini happy work in prototype mode on uno or mega.
i have accomplished sending email using ethernet both ethernet shield , enc28j60 ethernet card. using smtp2go resolve internet email blocking problems. not unfamiliar terrain.
it may simplest if send smtp direct rm04 did enc28j60, (which subject , 2 line notice)
an alternative route may use wifi card web-server sends http get/post via url "relay" site contain message. in case have send destination email address content. website email-fowarding process add subject , content.
somehow think if spi work between arduino , rm04 (knew pins numbers) rely on chunlinhan libary , figure out there, don't know if spi part of process have seen posts referencing chunlinhan libary use, 5v, ground, , pins 21 , 22 on rm04 , pin 0 , 1 on arduino.
i got both enc28j60 , regular ethernet shield sending email excellent work done create library jcw/ethercard on github , code @ end of post in case helps else. (some tweaks depending on card, think ethernet library called)
thanks work people have done , suggestions email sent view wifi either straight smtp or via web web relay.
i pieced stuff together, people noted in code examples did heavy lifting. sorry if got inadvertently deleted.
