AN-B-007 DA1458x Bluetooth Direct Test Mode
■This document is a guideline for testing the DA1458x SoC device in Bluetooth Direct Test Mode.
●Introduction
■DA1458x are Bluetooth®Smart SoC devices, working with extremely low power while providing world-class RF performance, a small footprint and flexible peripheral configurations for a wide range of applications.
■The DA1458x supports Direct Test Mode (DTM) for RF PHY testing as specified by the Bluetooth SIG. The Device Under Test (DUT) communicates with the Bluetooth tester over a 2-wire HCI UART. See Figure 1 for a description of the test setup.
■The DA1458x supports Direct Test Mode when used with the split embedded configuration of the firmware. The prod_test_58x. hex files can be found in the latest SDK and can be downloaded from the Dialog Customer Support site. Please read sections 4.1to 4.3.4 for setting up DTM for BluetoothRF testing.
■Additionally, using the latest Connection Manager tool and loading the same prod_test_58x. hex file, some production tests can be executed, for example: continuous modulated Tx output, Tx CW output and Rx testing with statistics. This test-mode is started when choosing ‘Boot Test Mode’ in the Connection Manager after downloading the prod_test_58x. hex file. This tool provides a GUI showing the available commands.
■Furthermore, a command line interface based executable is available (prodtest. exe),offering similar functionality. Please read sections 4.6and 4.7for setting up these production test tools.
