I have been struggling to get this to work for over a week now, and can't find any documentation about this. But then I realized this wasn't doing the calls over SSL but rather over plain http. Once the slave has connected and setup the secured websocket channel AND sent at least one RPC call to the master can be a dummy call of some sortat this point the master can do rpc calls towards the slave.

This should print 5 in the logs on the master. This way you could do for example a GPIO. Toggle of pin 5. Copy ca. On the client side I copied the client. Copy it to the client ESP mos put clientfile. Toggle call:. You can also setup a 'default' secure channel to the server that stays open. For that configure the default websocket on the client ESP Cfg. It will use the default open channel to do the call. This speeds up consecutive calls to the master, otherwiser for each call a handshake must be done that takes some time.

It provides a way of building responsive and low-latency web applications by providing a persistent bidirectional communication channel between the client and the server in real-time. The connection between both can remain open. This means that after the initial handshake, each frame carries only a small header which reduces overhead compared to plain HTTP, and most importantly, it allows for server-initiated push of the data as it becomes available rather than have the client actively poll the server.

This is often easier and less resource-intensive than using one channel for reporting and a second for controlling the device. Especially with increasing complexity of the control and reporting logic, the benefits of a bi-directional connection appear. This function returns a WebSocket connection.
