In my original post about creating an auto start system for the DVAP and RPI, I focused on the DVAP Node and ircDDB packages. At the end of the post I mentioned that Robin, AA4RC had published a version of his popular DVAPTool software for the RPI. I later updated the post to include a way to auto start DVAPTool after the RPI is booted. This system has worked very well for me.
Subsequently, I noticed a post by W2SWR with an alternative DVAPTool auto start method. You can download his instructions here. I have tried his method and it works very well.
Later, I noticed a great post to the DVAPDongle Yahoo! Group by KC8ZRM, describing a method to implement a 90 second delay in the auto start of DVAPTool to allow a WIFI connection to obtain an IP address. His email with these instructions can be found here. I have implemented this delay into my auto start system and it works as described.
I would recommend considering both of these suggestions when anyone is considering building an auto start DVAPTool system on the RPI.
