FLashing the new update

[kavin kumar]

Hello Team,

How to flash nRF52 DK for the latest update ? where can i found the latest update ?

I would recommend using the DTM example from the SDK for Bluetooth RF-PHY tests.

You can find the source code and the project file of the example in the following folder: <SDKInstallFolder>\examples\dtm\direct_test_mode

Same IUT where it is detected as J-Link cdc com port 8 but it is not communicating with Ellisys EBQ tester . How can i proceed to start testing with EBQ for LL and HCI testing ?

How to find BD_ADDR in nRF 58240 board ?

From the Bluetooth Core Specification Core version 5.0, page 2773:

Direct Test Mode shall be set up using one of two alternate methods:

1. over HCI (as defined in Section 2) or
2. through a 2-wire UART interface (as defined in Section 3)

Each DUT shall implement one of the two Direct Test Mode methods in order to test the Low Energy PHY layer.

The implementation in the SDK is for UART DTM, not HCI.

The BD_ADDR (bluetooth address) is derived from the NRF_FICR->DEVICEADDR[].

See this post on how it is derived.
