Hello Team,

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

Hi,

You can find the latest SDK version here (SDK14.2). The latest nRF5x Command Line Tools can be found here, this installer includes the Segger J-Link Software Pack v6.20i

Thanks ..How to bring up the virtual comport ? What is the use of nRF usb when it is connected nothing is coming up . Other one is used for power also ,comport is coming up but communication is not happening in that with the tester . Please help on this ..

This is nR52840 . I want this com port to communicate with BITE RF tester for BLE 5.0 RF PHY testing .

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

How to find BD_ADDR in nRF 58240 board ?

[Sigurd]

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.
