Absolutely; If you’re familiar with IoT and MQTT, then you have the basic knowledge on how the Waiter ECC communicates. The only restriction is, the controller circuit board is looking for a very specific SSID (WaiterControl) and a very specific IP address for the MQTT broker (192.168.50.10). These are currently hard coded in the controller card firmware. We anticipate changing this in the future so an end user can select their SSID and MQTT broker addresses, but for now, this was the simplest, most reliable way of ensuring wifi connectivity between the controller board and the operator touchscreen.
