Was anybody able to get mutual TLS authentication running on a WINC1500 Wifi module?
I am using the WINC1500 firmware V19.6.1. Mutual TLS authentication should be supported since V19.5.6 based on the firmware release notes. In my setup the WINC1500 acts as a MQTT client. TLS based communication without mutual TLS authentication works so far. All the required certificates are present on the module. The WINC1500 is able to detect the CertificateRequest from the server at print it out to the UART debug output. Put after that the connection got closed.
Do I need to enable this feature?
