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
- Replace DIC_CLIENT_ID macro value with your Client ID
- Replace device_certificate and device_key with your device cert and device key. (There is no need to change the CA certificate.)
The preferred certificate type to use in the application is ECDSA.
If using mosquitto, change the following file matter/examples/platform/silabs/DIC/matter_abs_interface/src/dic_nvm_cert.cpp enable USE_MOSQUITTO and disable USE_AWS.
Under #if USE_MOSQUITTO
- Replace DIC_CLIENT_ID macro value with your Client ID
- Replace ca_certficate, device_certificate and device_key with your ca_certficate, device cert and device key.
The preferred certificate type to use in the application is ECDSA.
