Unable to run client

[PhoenixCampbell]

While compiling, I am unable to run the client at the step indicated:

pm3 ~/client$ pm3 /dev/ttyACM0 [=] Waiting for Proxmark3 to appear... [=] Session log C:\Users\PHJCa\OneDrive\Documents\GitHub\ProxSpace-3.3\pm3/.proxmark3/log_20200404.txt [!!] ERROR: cannot parse command line. We got COM3 as port and now we got also: C:/Users/PHJCa/OneDrive/Documents/GitHub/ProxSpace-3.3/msys2/dev/ttyACM0

[!] ERROR: invalid serial port C:/Users/PHJCa/OneDrive/Documents/GitHub/ProxSpace-3.3/msys2/dev/ttyACM0

I was wondering what I am doing wrong. I was also following along with the video installation as well, wondering if that led to problems as well as written direction.

either you use the scripts which tries to find which serial port you are on.

./pm3

or if you run it from root folder,

./client/proxmark3.exe -p /dev/ttyACM0

i got it to work, one last question, how do you switch from offline to online mode. That seems to be my last problem.

Good that you solved your issue.

And sorry, I don't understand that question.
If you are asking about standalone mode, there is plenty of documents here in the repo that covers that part.
