I have my door opener working with V3 Ethernet board and seeedo 4 relay V2 board, It communicated correctly when initially powered and I have managed to operate each of the 4 relays. The problem is I keep getting communications time out errors each time I toggle a relay or even when refreshing the communications? Sometimes it is a communications parsing error?
If I cycle power to the arduino and restart my Iphone 5 app it all connects immediately again.I have checked the power supply and it is sufficently rated for the power requirements and I have trialled another power supply to be sure it isn't the cause.
I also upgraded to the 1.5 version of the Arduino IDE as I thought this may improve the issue.
