Thread CLI CMakeLists.txt file issue

[Allen]

Hello,

I modified the CMakeLists.txt file and now I am able to compile the Thread CLI application. However I noticed something strange in the CMakeLists.txt file.

list(INSERT OVERLAY_CONFIG 0 /opt/nordic/ncs/v1.7.0/nrf/samples/openthread/common/overlay-ot-defaults.conf)

What is the "0" immediately after OVERLAY_CONFIG in the line above?

Another question: Is adding multi-protocol as simple as adding "./overlay-minimal_multiprotocol.conf" to the end of the "INSERT OVERLAY_CONFIG" line?

Thanks

[Charlie]

Hi Alles,

INSERT is one of CMake document defines List operations. You can learn CMakeLists.txt format from it.

Best regards,

1. according to the CMake documentation the "0" in the INSERT command is an error. The index is only relevant when performing a indexed operation into a list like "GET"

2. You did not answer the question about how to use the overlay conf file to add multi-protocol support. I have read the documentation and is says to enable the SoftDevice in Kconfig to enable the ability to configure BLE options. I can not find anything regarding the overlay files provided in the project'

1. No, "0" is not an error. According to the CMake list format: list(INSERT <list> <element_index> <element> [<element> ...]), "list(INSERT OVERLAY_CONFIG 0 /opt/nordic/ncs/v1.7.0/nrf/samples/openthread/common/overlay-ot-defaults.conf)" insert the path to the first position of OVERLAY_CONFIG list.

2. You can add another line like "list(INSERT OVERLAY_CONFIG 1 ./overlay-minimal_multiprotocol.conf)", but this is not suggested since it is one optional configuration. It should be added on compilling command, like "west build -d nrf52840dk_nrf52840 -- -DOVERLAY_CONFIG=overlay-minimal_multiprotocol.conf". nRF Connect VS code Extentsion will do this for you when your choose the option from UI.

Best regards,

Charlie

Thanks Charlie,

I missed the fragments option.

This was very helpful

Is there a file you can edit to get VS code to specify the overlay if the project was not initially configured that way?
