We have an application where we want to connect wirelessly from a tablet to a Phidgets SBC with multiple interface kits attached. I saw the 802.11 adapters that would provide WiFi, but no Bluetooth. Is there any Bluetooth solution we could use in this environment? We don't really want to expose these units on an 802.11 WiFi network. We also may need to connect to multiple SBCs from the same tablet...
You might consider getting a WiFi dongle for the SBC which supports master mode, and configuring the SBC itself as a wifi access point to connect to with your tablet. Getting IP over bluetooth working would be significantly more work.
Hostapd was working, but has now stopped and nothing I do will get it to start again. I did disable webif update using update-rc.d phidgetsbcwebif disable as suggested by Patrick. I am wondering if something else in the SBC setup or startup controls the wifi adapter. It still seems available on the web page. any help is appreciated.
It seems that wpa_supplicant is the issue. If I kill this process then hostapd works. I think i'll edit the /etc/wpa_supplicant/wpa_supplicant.conf file and see if that will somehow stop this from interfering. Any input on the correct way to handle this would be appreciated.
You will also need to move/delete the file: /lib/udev/rules.d/60-usb-wifi.rules - this starts up wpa_supplicant when the USB dongle is plugged in / on boot.
