As the convener for the Adelaide community of The Things Network, I am frequently setting up Multitech Conduit Gateways. Depending on your PC or notebook hardware you might have some problems with the Exar USB-UART driver on Linux.

Here are the steps to getting this unit setup from an Ubuntu (should work for any other Linux distro) machine.

Should show something like this:

Bus 002 Device 006: ID 04e2:1410 Exar Corp. XR21V1410 USB-UART IC

If you are using the GUI (Raspian full download) and want to connect your RPi Zero to a keyboard and monitor there are probably easier ways to do this. These notes are for people that want to use a headless (no monitor and GUI) setup ready to connect to your RPi after first boot via SSH from another terminal.

Testing the RPi for some remote sensing application I needed to use a wireless connection as it would have been a pain to reach with an Ethernet cable.

Parts

• Raspberry Pi Series B 512MB
• Raspbian 3.6.11+ Kernel
• Comfast 802.11n – Realtek RTL8188CUS WLAN Adapter

Install WPA Supplicant

sudo apt-get install wpasupplicant
See http://en.wikipedia.org/wiki/Wpa_supplicant

Check for the USB adapter

sudo lsusb
This should show output similar to this (depending on your USB adapter)
Bus 001 Device 004: ID 0bda:8176 Realtek SemicondRTL8188CUSuctor Corp. 802.11n WL:AN Adapter

One of my oldest pieces of hardware is a trusty Nokia SU-8W Bluetooth Keyboard. I have tried to revive it on an Android 1.6 & 2.0 device with not much luck. However I got it working successfully on a Gingerbread (2.3.4) Google Nexus S.

Pre-requisites

• SU-8W Manual (http://nds1.nokia.com/phones/files/guides/Nokia_SU-8W_Wireless_Keyboard_UG_en.pdf)
• BlueKeyboard JP (https://market.android.com/details?id=elbrain.bluekeyboard.ime)

Steps

1. Install the BlueKeyboard JP from the Android Market
2. Go to Settings > Wireless & Networks > Bluetooth Settings
3. Scan for devices and click to pair the Nokia SU-8W
4. Enter a passcode (I used the highly inventive 0000 combinaton) on the phone and click ‘OK’
5. Enter the same on the SU-8W (need to use green ‘fn’ keys for numbers) and hit enter
6. The phone should show the Nokia SU-8W as paired but not connected
7. Go to Settings > Language & keyboard > BlueKeyboard JP Settings
8. Select the Nokia SU-8W as the keyboard and make any other changes you might need
9. Click the ‘Back’ symbol and tick the option box to enable the ‘BlueKeyboard JP’ keyboard
10. In any data entry field (i.e. GMail) hold the finger on the input box and click ‘Input method’ and select BlueKeyboard JP
11. Wait for the keyboard to connect.

Enjoy !
