As the USB access did not work as intended, I got a little bit frustrated and started to poke around on the K2 to see if I can find something interesting. And well...I did :-)
First of all...you can access the K2 with your browser. Simply connect your laptop, tablet, phone or what else to your K2 and go to:
This will give you access to your sd card.
Another URL I found is:
This will give you access to the live view
Looks like this
Well...this is nice, but I wanted at least the same access the App has, so I poked more. Which means I captured the network traffic between the App and the K2 to see what the App is doing. Sadly the App isn't very stable, so I had to start over the whole process every some seconds, causing me only to get some of the commands the App sends to the K2.
But, on the positive side, now as I knew some commands, I was able to simply ask Google if there is something about that in the net. And yes...I found the complete wifi-command user guide for the Novatek NT9666x. Sometimes things are easy :-)
So what is possible with these commands?
First of all, you can do the same as the App does. Means switching GPS on/off, settings G-Sensor sensitivity, select resolution, etc. But there are some more interesting things.
Set time and date
Something the App does automatically. Now you can do it manually.
Delete all files
Allows you to delete all files. No more need to format the card to remove all files.
Change PIP style
Allows you to change the style of the live view (front only, rear, only, front major, rear major)
Helps a little bit when aligning the cameras.
Allows you to change the bitrate of the front cam. Rear cam seems to keep its default bitrate.
Change Wifi-Connection mode
Allows you to set the K2 in station mode to connect to your home wlan.
And yes...that works, but transfer speed is still awfull. Your wlan password must not contain special characters. At least the = character is not allowed.
Here is a screenshot of my K2 in my home wlan.
When the K2 is in your home wlan, the App isn't working anymore, as the K2 does not offer a wlan anymore. Changing wifi mode takes three commands (set ssid and password / set wifi mode / start wifi-reconnect)
How is it done?
The commands must be send as an URL to the K2. The syntax is...
xxx = the function you would like to active or change
yyy = the value you would like to set
(see Wifi Command guide)
will stop recording. While..
..will start recording
will delete all files (there is no "par" here)
You will find the Novatek Wifi-Command List in my Dropbox share
All settings commands are instantly effective, but will only be saved when the K2 shuts down properly. Means you can play around without the worry to mess something up. For example, if you change the wlan mode and it is not working, you can simply cut of power to the K2 to revert back to the old settings.
