XV-21 wifi mod

Postby mb300sd » July 11th, 2014, 12:54 am

I modified my XV-21 with a wifi connection today. It has the new rev64 pcb without the serial connectors, so I embedded a TL-WR703N inside it. The router fits perfectly in the casing and barely moves when it's closed.

The router drew a little too much power to tap off the internal regulators, so I also added a switching regulator module connected to the battery voltage. I think the locations I tapped are after the board's current sensors so it shows up in the battery management software.

I desoldered the USB port from the router and connected it directly to the neato board. USB power can be toggled by software in the router, although the most recent firmware doesn't seem to care if its connected or not (I read somewhere another version won't clean with USB connected).

I've uploaded a custom OpenWrt image with only the needed packages included, along with a copy of my config. It creates a network called XV21 with the Neato's serial port shared on tcp port 2000.

Standard openwrt installation instructions apply. Upload files.tar.gz after it's installed, extract to /, run setup.sh, and reboot.

If your vacuum won't clean with USB connected, add
"echo 0 > /sys/class/gpio/gpio8/value" to /etc/rc.local to turn off the USB port on boot, use "echo 1 > /sys/class/gpio/gpio8/value" to turn it back on.

Great work! Very elegant way of hacking a wifi module into a neato.

Only gripe i have with the botvac is that the usb port is in the dustbin container; you just can't do anything apart from updates with it.

Does it not have any commands at all, or is the port just inaccessible because of the dustbin? I soldered directly to the mainboard USB signals without using the port.

It has commands and receives and echos just fine and all commands are just fine, it's just that the dustbin has to be removed while the usb is plugged in.

Great, plan to run this as well, can you also monitor sensors while neato is running ?
can you upload the file "xv-21" again since the link does nothing but asking me to register.

Did anyone manage to run this wifi mode with the same configuration and can help with the "xv-21" file?
Appreciate some help.
