Reply To: Broker address typed into a config page as text: how do I turn the string into something the ESP32 can use?

fromString worked for the Pi, and then I switched to the char buffer version. Aoife you were right about the pointer: my first try with c_str() connected once and then failed every reconnect with rc=-2. With the global buffer it’s fine, and the shed board is now talking to Hermetry with the host typed into the setup page.
