[question] Kotlin Android examples

[phanminhtien]

Dear all,
My MQTT Broker is build by using aedes. It have cert.pem and prvikey.pem.
By using cert.pem and prvikey.pem I can connect to MQTT Broker via WSS by using Python and React.
But when I try to connect MQTT Broker by using Kotlin Android, I can not connect to it.
I edit code Two-way authentication ( Link ) to only using cert.pem and prvikey.pem to try connect to MQTT Broker, but not successful.
If you have any examples by using Kotlin, or other way. Please help me. Thanks a lots
