5.5. What to do when the module cannot connect to EPAT?
If the module cannot connect to EPAT, check whether it is connected to the PC correctly.
If it is connected to the PC correctly, check whether the port selected for log capture is correct.
If the port is incorrect, try other ports to find the correct one.
If you have tried all ports and still cannot find a suitable one, check whether the baud rate is correct.
If the baud rate set on EPAT is inconsistent with the baud rate set with AT+QCFG, garbled data may be
output.
If the USB-UART bridge chip does not support the baud rate you configured, nothing will be output. To
solve that, you need to modify the configuration so that the baud rate adapts to the chip.
