Tips

  • New applications once installed show up in the "My Own" or "My Installations" folder
  • Make a new ad-hoc network: Tools -> Settings -> Connection -> Access Points -> Options -> New Access Point
  • Manually assigning an IP address to the phone: Tools -> Settings -> Connection -> Access Points -> (Choose your ad-hoc ap) -> Options -> Advanced Settings -> IP4 Phone IP Address
  • You will need to register the phone to the CSE network if you wish to communicate with department machines. Getting the WLAN MAC address requires the codes listed below.
  • If the Nokia phone is running as a Bluetooth client, it has to do a device inquiry, it does not support connecting to a known service on a known device. This is a limitation of the implementation of JavaME on the phones, but should work in Symbian.
  • JavaME apps cannot run as a background process. They can be put into the background through a PushRegistry command that essentially stops them. They can then be restarted via a timer or incoming network process. True background apps can only be done in Symbian.
