OK. Here's the log https://dl.dropboxusercontent.com/u/94009991/sg_logfile_20160701221638.txt
It doesn't really tell me much about the camera connect problem.
However, I am repeatedly not able to connect to the 70D when I start SGP and try.
If I close SGP and start BYE and connect to the 70D, then disconnect, close BYE, start SGP again, I am then able to connect to the 70D.
I have repeated this several times now and it's the only way for me to get SGP to connect to the 70D. A little odd.
If I didn't have BYE I may not be able to connect at all? Hmmm.
Any other ideas to fix this let me know. I haven't got a clue. I am using the correct mode (bulb).
Thank you.
