1. Install 2021 RC1 firmware.

2. Create a user library named websocket using the attached source.

3. Upload certificates via FTP using ftp login, rename files with long names to cert.pem and key.pem accordingly.
4. Create a resident script with 0 sleep time.

Code:

if not client then
  require('json')
  ws = require('websocket')
  url = 'wss://test-hub.usbim.com'

  client, err = ws.client('sync', 1)

  opts = {
    protocol = 'tlsv13',
    key = '/home/ftp/key.pem',
    password = [[*q&'wrKQsx+#bj8pbEV=%7Gpr"S+sxV2ngr`N}SjCC`X#rtt!wY6PL`d2'3!^x}u]],
    certificate = '/home/ftp/cert.pem',
    cafile = '/home/ftp/ca-chain.cert.pem',
  }

  res, err = client:connect(url, opts)
  if not res then
    log('connection failed', err)
    client:sock_close()
    client = nil
  end
end

if client then
  frame, opcode, clean, code, reason = client:receive()
  log(frame, opcode, clean, code, reason)
  if frame then
    data = json.pcdecode(frame)
    log(data)
  elseif reason ~= 'timeout' then
    log('connection dropped', reason)
    client:sock_close()
    client = nil
  end
end

This example is only a starting point, it should be extended with additional send/receive logic.
