Development and Testing
4.1.
Debug of the Module in the Final Application
To test, debug and reprogram a module in the final application, Telit strongly
recommends having the interfaces listed below externally accessible or available via
test pads on the host PCB.
This allows testing of the connection between the module and the application and to
test the performance of the module using an external computer or test set.
Depending on the customer application, these pads include, but are not limited to,
the following signals:
TXD
RXD
ON/OFF
RESET
GND
VBATT
TX_TRACE
RX_TRACE
PWRMON
USB
D+
USB
D-
USB
V_BUS
USB_ID
TIP
: If the application uses USB as the main interface to the module, this is sufficient
to capture any debug and trace data (no other UARTS needed) provided the
application can export the data stream from the USB Diagnostic Port.
4.2. Development
Kit
To assist with the development of Telit CC864-DUAL based applications, the EVK2
Evaluation Kit is available which provides the following: RS232 serial port level
translator, direct UART connection, USB connection, Handset, Headset and Hands-
free(car kit) audio and antenna.
The EVK2 provides a fully functional reference solution for a data/phone application.
