Hi

I have the recommended wireless USB adaptor for the Camera Pi Robot

I have tested it on my other Pi (with no robot and camera connected) by following on line instructions and altering /etc/wpa.config and /etc/network/interfaces. It works fine.

When I use it with my other identical Pi which is on the robot it fails. I can not connect to the 'Pi_Mini_Robot’ network at all. I have disconnected the usb and power to the Mini driver so power should not be an issue as I have used the same 1A power supply I used to test on my other Pi (unless running it as a wireless access point uses more power?!)

Any pointer?

Also, why is this set up as a Wireless Access Point. When I have a cable plugged in, it gets a normal IP address via DHCP and I can control the motors fine. By having it as a Wireless Access Point I have to disconnect from my router and loose my Internet connection in order to use the Pi's motors. Am I missing something here? Should I be able to log in to both the Pi_Mini_Robot network and my router if the former worked?

Hi there,

One issue which as tripped people up in the past is that the password for the network 'Raspberry' is case sensitive with a capital 'R'. Probably should have changed this a while back, but it was inherited from an Adafruit tutorial and I've put the current spelling in lots of places now.

The SD card image is set up as an access point simply to make it easy for people to connect to using a smartphone or a tablet. Sorry, I agree that it does make it a bit awkward for people wanting to connect to it from a Desktop PC and browse the internet at the same time, but I haven't got a great way to make it an easily configurable option yet. The network configuration of the Pi can be modified in a number of different ways. This tutorial looks to be fairly good for setting up WiFi networking to a router, although you may need to replace the /etc/network/interfaces file with one from a standard Raspbian install before the GUI WiFi network tools work properly.

You can edit the access point SSID, channel and access point by editing the configuration file with

Code: Select all

sudo nano /etc/hostapd/hostapd.conf

Please let me know how you get on with connecting to it wirelessly. If it's not a password issue then we can look at some other options.
