Printing the security mode and level of bluetooth

[prashaanth]

I am using a nrf52840 dongle with SEGGER. I am trying to find the security mode and level of the bluetooth initially and after getting paired to another device too. My moto is to check for the security negotiation in the bluetooth layer when it pairs with another device. I have a firmware code with me in which I have integrated the nrf5 17 version SDK(https://www.nordicsemi.com/Products/Development-software/nRF5-SDK)

Steps performed:

I am using Segger tool to build.

I create a new project first selected yellow highlighted option


Selected my target board as nrf52840_xxAA. Then did these,

1) Right click go to options--> preprocessor--> include directories and include all these,

2) In preprocessor Definitions add this "NRF52840_XXAA"

"BOARD_PCA10056"

 

3)Open options--> add existing file and add these source files

Ditch the SDK17, migrate to NRF Connect SDK. This old software is in maintenance mode and should not be used for any new projects.

Hi, 

I am trying to download the nrf connect toolchain in vs code but getting this error

Error: Failed with exit code 1. Failed to download toolchain bundle Caused by: An existing connection was forcibly closed by the remote host. (os error 10054).

during nrf connect sdk download

Tried the same in nrf connect desktop app getting same issue. Any idea how to resolve this
