Can't find the dash button using the libpcap library #22

I'm having trouble trying to capture my dash button using "findbutton", but I know it works since it discovers another random iot device in my house every minute. I ruled out the device being the issue since I was able to see it using wireshark from the same linux mint vm (packet: AmazonTe_27:9f:69 (f0:27:2d:27:9f:69)).

Just to make sure it wasn't the configuration that was the issue, I changed the mac address to the device I mentioned above and it successfully connected and printed a message when the device connected (using dash-rickroll).

Hi @bsherertz. Very impressive debugging! Can you provide a couple more pieces of background:

Thanks @ecaron and the information is below:

node version = 5.4.1 npm is 3.3.12 ifconfig:

It looks like there are 8 to 12 white blinks on average then around 3 to 4 red blinks followed by a longer red (this could be the issue). I did notice after trying wireshark inside my linux mint vm that it was unable to find the wireless dongle so this could be a driver issue (wireless works though from a usb dongle connected inside the vm using vmware). I'll try this with my ubuntu vm and see if this is the issue.

Wow...looks like I just had to restart the vm and plug the wifi adapter into another outlet. Please disregard the issue and thanks for the quick response.
