Known Issues

  • If you regenerate and build the AWS IoT applications, you could encounter a build error "wdrv_winc_enterprise.h: No such file or directory". This can be overcome by commenting the line of code "//#include "wdrv_winc_enterprise.h" in driver/winc/include/wdrv_winc_client_api.h file. This patch is applied due to a known issue in "wireless_wifi" repo. The issue is expected to be fixed in a future release of "wireless_wifi" repository.
