7.3.2 Adding a Certificate to the WINC Trusted Root Certificate Store

  • Before connecting to a TLS Server, the root certificate of the server must be installed on the ATWINC15x0. If this is not done, the TLS connection to the server is locally aborted by the WINC.
  • The root certificate must be in DER format. If it is not provided in DER format, it must be converted before installation. Refer to Section 17 “How to Generate Certificates” for certificate formats and conversion methods.
  • To install the certificate, execute root_certificate_downloader.exe with the following syntax:
    root_certificate_downloader.exe -n N File1.cer File2.cer .... FileN.cer
