NRF52832 HCI interface (zephyr HCI UART using seggar Embedded Studio)

[Chandra2sekhar]

Hello,

we are using NRF9160 +Nrf52832 in a project. NRf52832 has to be used as HCI interface..after searching for this, i came to know that zephyr based HCI uart sample needs to be build & programmed to the 52832. can i able to build the sample from zephyr rtos hci uart sample using seggar embedded studio. i tried "open nrf connect sdk" using nordic version of seggar.. after pointing to cmake,and boards, project not loaded. it gives out some errors..can anyone help me out with how to open & necessary conf files to use samples from zephyr rtos using seggar studio .Thank you

Take a look at the NCS tutorial for guidance on how to build a sample, properly:

• https://devzone.nordicsemi.com/nordic/nrf-connect-sdk-guides/b/getting-started/posts/nrf-connect-sdk-tutorial
• https://devzone.nordicsemi.com/nordic/nrf-connect-sdk-guides/b/getting-started/posts/nrf-connect-sdk-tutorial---part-1-ncs-v1-3-0

Could you provide a screenshot of the nRF Connect Options you've chosen (CMakeLists.txt, Board Directory etc..). Please provide a screenshot of the error messages you're getting, as well?

Are you using the Toolchain Manager? If not I would highly recommend you to, as it simplifies the building process.

Best regards,

Simon

Hi simon,

Thanks for your reply. To reclarify you, i am trying to use Nordic version of embedded system studio, & trying to build the HCI UART sample which is in Zephyr master github. i doubt if NCS & zephyr both are same or different.

i am trying to open build the HCI Uart Sample from zephyr master github, using the seggar embedded studio..help me how to load it,and build it. i am completely new to Zephyr, cmake & command line building, attached is the screenshot

Hello Simon,

Thanks for your reply. i am already using tool chain manager,& NCS. i dont see any sample code for hci Uart  inside the ncs1.3.0 thats the reason i am trying to get it from zephyr as mentioned in many posts on this forum. have a look at the error, it says,something wrong with the cmake. also some config files is missing..help me correct it..

i am already running so late, we need to push the product to market asap..Thank you

if you have any properly configured sample of Hci Uart send it over, i will paste it in the ncs folder and try to open it.Thank you

Now, I see what's wrong. You chose the wrong board folder. Choose this:

C:/Nordic/zephyr-master/zephyr-master/boards/arm/nrf52dk_nrf52832

instead of this

C:/Nordic/zephyr-master/zephyr-master/samples/bluetooth/hci_uart/boards/nrf52dk_nrf52832

By the way, if you have opened SES from the Toolchain Manager, the Zephyr Base will be set automatically, and you should use the same Zephyr folder when building your projects. E.g. when I open NCS v1.3.0 through the Toolchain Manager and SES, the following Zephyr Base will be set in Tools-->Options-->nRF Connect-->Zephyr Base:

C:\Users\<user name>\ncs\v1.3.0\zephyr

Best regards,

Simon

Hello,

i followed your instructions, still same issue..

i have one more point to let you know, i see that , the zephyr folder inside the ncs1.3.0 is just 23.5mb and i see only .git folder.. there is no other files.. likely i doubt some thing is wrong with the installation..i used tool chain manager only.

look at the folder contents..

let me know how to reinstall it..Thank you

Try to reinstall it.

• First, remove it:

• Then install it:

Thanks ,i removed it.. but i have a network problem from many days,..when i try to open nrf connect app, i get Error network changed.. and tool manger also does not shows any sdks.have a look at this.earlier after so many retires, manually downloading the nrf tools ,and copying it to directory , i managed it..

always from beginning i have this network issue with nrf connect

Hello

after reinstalling the ncs 1.3.0 i was able to load the project & build it with default sample. can you please help me out with how  to add overlay file to change the pin numbers,& where can i get information about the how to write the conf & overlay files, its inputs, etc. in which folder it needs to be saved..Thank you
