According to the manual, it is possible to power up the K2 by inserting a USB cable into the USB port, applying power to the unit, and theoretically allowing us to interact with the K2 when connected over WiFi.
However, I discovered from Frostie that if you power the K2 by connecting the USB cable to your PC, you've actually put the unit in USB mode, which disables WiFi, causing the K2 to no longer broadcast a WiFi Hotspot.
So, if you power the unit using a USB cable, plugged into a charger, instead of plugging into the PC, you'll find that the K2 begins to broadcast a proper WiFi signal, and you can connect to it.
Thanks Frostie
Update: It seems my earlier problems were due to one, or both, of 2 things:
1) bad USB cable making an intermittent connection.
2) possibly defective camera.
The K2 DVR's WiFi will come up and connect when powered via USB. Based on older posts, you have to have at least a front camera connected, which was why I thought to swap it out. As I said, I've done lots of testing (and even recording) in "bench" mode powered via USB, so it's definitely a thing.
Once I used a different USB charger with a different cable, and swapped cameras, the DVR came up normally and appeared on WiFi.
FWIW, I tried the newer app that is simply called "Innovv." Some features worked but it was unable to show a live video stream from the connected camera. The older "Innovv K2" app worked fine. This is promising. I should be able to re-use my K2 on my next bike.
The lights come on and it appears to work otherwise. I was even able to re-flash it with firmware. But since I can't connect to it over WiFi, I can't access any of the functions.
You could flash the firmware which enables logging. This way you could check the logs to see whether the K2 starts wifi or not.
That's not correct. As I said, I've powered the K2 via USB charger many times before. Both for off-bike, at-home testing, and on the bike when I was troubleshooting the old power converter design. It's just not cooperating now. Must be some invisible damage from the crash, or from sitting in the junkyard for most of a month. Some idiot tore off the rubber strip that covers the ports on the side. Must have gotten rained in. Surprised it powers up at all.
If you use the USB connection for power, the WiFi is switched off.
To enable WiFi, you need to connect the K2 to the power module.
I am having a related problem.
My K2 was in a crash a while ago. Eventually I was able to retrieve the whole system (DVR, cameras, GPS antenna, even the power converter) from the wreck. I've tried connecting the DVR to a USB power supply (wall charger, not to a PC). It used to work fine this way for "bench" testing at home.
But now it won't show up on WiFi. The signal just never appears.
The lights come on and it appears to work otherwise. I was even able to re-flash it with firmware. But since I can't connect to it over WiFi, I can't access any of the functions. I also tried pressing the hardware reset button under the rubber cover. Made no difference.
Is there anything else to try? The DVR was not physically damaged in the crash, so I don't know why the WiFi doesn't work.
no wifi signal is detected on my phone from the K2 when i turn the bike on ' what can cause that ?
@innovv
Could anyone please remove all the spam postings above (and in the other threads)? I reported them weeks ago and keep doing so, but it seems nobody cares.
I'm not experiencing the same result. I have it plugged into the wall and no wifi signal is detected on my phone from the K2. I have a Galaxy S9 in airplane mode with the wifi turned on. I can see all my other networks.
Thank you for reminder and listing.
