More ways to use SerialMagic

This document outlines how to use SerialMagic Professional software, running on a Symbol MC9090 ruggedized handheld, to capture data from a Pneu-Logic Tyre probe, and then switch devices and begin capturing data from another Pneu-Logic Tyre (Tire) Probe.

Here are the main components of this setup:
1) Symbol MC9090 Ruggedized Handheld running Windows Mobile 5
2) SerialMagic Professional software running on the handheld
3) Two (2) Pneu-Logic Bluetooth Tyre Probes
4) Excel spreadsheet on the handheld

Important Note: The MC9090 has Stonestreet One Bluetooth stack. The stack implementation limits ONE application to communicate with the Bluetooth stack. This means that if BTExplorer is started on the MC9090 you must stop it, and turn off Bluetooth before using SerialMagic. That is correct Bluetooth should be OFF. Apparently Bluetooth icon on the Windows Mobile Today screen is considered an application.

Note: To use SerialMagic Professional with the Pneu-Logic tire Probe on Windows Mobile devices with Microsoft and WidComm Bluetooth stacks, do NOT turn off Bluetooth as outlined above for StoneStreet Bluetooth stack.

First, you will need to download and install SerialMagic Professional for Windows Mobile (Pocket-PC) onto the Symbol MC9090.

Next, launch SerialMagic Professional on the Symbol MC9090 handheld, and power on the first Pneu Logic Tyre Probe.

Connect First Tire Probe
First, check to make sure that the Device Type is "Pneu-Logic Probe" (Go to Setup > Select Device)

Next, if you wish to connect to a New Device, go to Setup > Connection, and make sure "Choose New Device" is selected.

Now, START SerialMagic to begin the connection process. SerialMagic will display a list of nearby Bluetooth Devices.
Select the device you wish to connect to, in this case "Pneu Logic Probe DDEM412." Then tap OK.

Next, enter the passkey for the Probe, the passkey is "1234." Then tap OK to complete the pairing / connection.
Once Connected, SerialMagic will minimize itself to the taskbar. If you bring up the application, you will see "Status: Connected."
Launch the target application (the application to receive the data), in this case Excel Mobile.
Place your cursor in the desired cell, and take a reading with the Probe. See the data appear in Excel, like magic!

Connect Second Tire Probe
Now, to connect to another Pneu-Logic Probe, go back to SerialMagic, and hit "STOP."
To indicate to SerialMagic you wish to connect with a New Device, you can go to Setup > Connection, or tap-and-hold on the "Last Device."
(Below-right, you will see the "Choose New Device" shortcut appear, select it). Then hit START to begin the new connection.

SerialMagic will first display a list of "Paired Devices." If you wish to start a new Search, choose Menu > Discover.
Once the Discovery is completed, select the desired device to connect with. In this case, the "Pneu Logic Probe DL70330." Tap OK.

Enter the Passkey for the Probe, which is "1234." Tap OK.
Once Connected, SerialMagic will minimize itself to the taskbar. If you bring up the application, you will see "Status: Connected."
Launch Excel Mobile once again, place your cursor in the target location, and take readings from the new Probe!

*Once the Passkey/Pairing process has been completed for a device, SerialMagic no longer requires the Passkey.*
