Build Procedure For Direct Internet Connectivity (DIC)

Build command with DIC

  • To enable DIC functionality use the enable_dic=true flag.

Here is an example to build the lighting-app with DIC feature for the EFR32MG24 + 9116

./scripts/examples/gn_silabs_example.sh examples/lighting-app/silabs/ out/rs9116_DIC_light BRD418XX disable_lcd=true use_external_flash=false chip_enable_wifi_ipv4=true enable_dic=true chip_enable_ble_rs911x=true --wifi rs9116

Here is an example to build the lighting-app with DIC feature for the EFR32MG24 + WF200

./scripts/examples/gn_silabs_example.sh examples/lighting-app/silabs/ out/wf200_DIC_light BRD418XX chip_build_libshell=false chip_enable_wifi_ipv4=true enable_dic=true --wifi wf200

Here is an example to build the lighting-app with DIC for the EFR32MG24 + 917 NCP

./scripts/examples/gn_silabs_example.sh examples/lighting-app/silabs/ out/siwx917_DIC_light BRD418XX disable_lcd=true use_external_flash=false chip_enable_wifi_ipv4=true enable_dic=true chip_enable_ble_rs911x=true --wifi SiWx917

Here is an example to build the lighting-app with DIC for the SiWx917 SoC

./scripts/examples/gn_silabs_example.sh examples/lighting-app/silabs/ out/siwx917_DIC_light BRD4325B enable_dic=true chip_enable_wifi_ipv4=true

Build command with DIC AWS OTA

  • To enable DIC AWS OTA functionality use the aws_sdk_ota=true flag.

Here is an example to build the lighting-app with DIC feature for the EFR32MG24 + 9116

./scripts/examples/gn_silabs_example.sh examples/lighting-app/silabs/ out/rs9116_DIC_light BRD418XX disable_lcd=true use_external_flash=false chip_enable_wifi_ipv4=true enable_dic=true aws_sdk_ota=true chip_enable_ble_rs911x=true --wifi rs9116

Here is an example to build the lighting-app with DIC feature for the EFR32MG24 + WF200

./scripts/examples/gn_silabs_example.sh examples/lighting-app/silabs/ out/wf200_DIC_light BRD418XX chip_build_libshell=false chip_enable_wifi_ipv4=true enable_dic=true aws_sdk_ota=true --wifi wf200

Here is an example to build the lighting-app with DIC for the EFR32MG24 + 917 NCP

./scripts/examples/gn_silabs_example.sh examples/lighting-app/silabs/ out/siwx917_DIC_light BRD418XX disable_lcd=true use_external_flash=false chip_enable_wifi_ipv4=true enable_dic=true aws_sdk_ota=true chip_enable_ble_rs911x=true --wifi SiWx917

Compile using new/different certificates

  • Two devices should not use the same Client ID. To use a different Client ID for your second connection do the following:

  • If using AWS, Change the following file examples/platform/silabs/DIC/matter_abs_interface/src/dic_nvm_cert.cpp under #if USE_AWS

    • provide device_certificate and device_key with your device cert and device key. (There is no need to change the CA certificate.), Refer Openssl Certificate Creation

    • provide DIC_SERVER_HOST with your hostname

    • provide DIC_CLIENT_ID macro value with your Client ID in examples/platform/silabs/DIC/matter_abs_interface/include/dic_config.h file

  • The preferred certificate type to use in the application is ECDSA.

  • If using mosquitto, change the following files matter/examples/platform/silabs/DIC/matter_abs_interface/src/dic_nvm_cert.cpp and examples/platform/silabs/DIC/matter_abs_interface/include/dic_config.h enable USE_MOSQUITTO and disable USE_AWS.

  • Under #if USE_MOSQUITTO

    • provide DIC_CLIENT_ID macro value with your Client ID

    • provide DIC_SERVER_HOST with your hostname

    • provide ca_certificate, device_certificate and device_key with your ca_certificate, device cert and device key. Refer Openssl Certificate Creation

    • provide mosquitto client user in DIC_CLIENT_USER and password im DIC_CLIENT_PASS in examples/platform/silabs/DIC/matter_abs_interface/include/dic_config.h file.

  • The preferred certificate type to use in the application is ECDSA.
