“The communication will work without monitoring CTS, but in order to achieve minimum packet loss it is recommended to monitor CTS so your host MCU will be notified (and stop UART data) when the module (either Router
or Gateway) is busy doing transmissions (in a mesh network) or doing network maintenance, which is happening on a regular basis (automatically, to decide the optimum network configuration at any time)
