1 Introduction
1.1 Migrating from Bluetooth 1.1 to 2.0 products
A migration from a cB-OEMSPA13 or cB-OEMSPA33 module to a cB-OEMSPA311 or cB-
OEMSPA331 module is normally done without any problems. Even so, there are some issues
that have to be considered.

The resistance value of the pull-down resistors needs to be decreased to 1kΩ. It is especially
important to be observant on the Mode and Switch-1 signals. This point is not necessary for
the cB-OEMSPA333 modules and 10kΩ can still be used. See the LED and Switch Design
Examples for more info.
The High- and Low-signal definitions are slightly changed on the Logic Level signals.
Especially consider the Low-level definition on the Switch-0 signal. See the Input/Output
signals in the Characteristics section for more info.
A 5V system using resistor dividers to adapt the 5V TxD output signal of the host to the 3V
levels of the OEMSPA RxD input signal should decrease the resistor values to 1.8kΩ and
2.2kΩ. See the Logic Levels Design Examples for more info.
The Serial Port Adapter AT Commands document contains a description of the AT com-
mands supported in the Serial Port Adapter. It also contains information on how to use the
AT commands to create Bluetooth applications.
