The actual port used to connect to the IoT module can be manually adjusted. Note: If Raspberry Pi model 4B is used, the serial port configuration may be changed, using either ttyAMA0 or ttyS0 depending on UART configuration and config.txt settings.Increase UART clock to enable 500Kbps: modify /boot/config.txt to include a init_uart_clock=8000000.

A long-running calculation implemented purely in C (such as. Raspberry Pi native UART requires some modifications to be usable by RF Explorer IoT module: From Python 3.3 onwards, you can use the faulthandler module to report on synchronous errors.Search for official documentation or see this link.

Otherwise they may create significant RF noise and interference with sensitive RF circuit inside the RF Explorer IoT module.
