Click the button “Ok” on the Advance Settings dialogue.5. Finally, click the “Ok” button on the properties dialogue.Observe that this needs to be done for each new virtual FTDI COM port. E.g. for each connected USBdongle.10.2 Change UART baud rate of PBA31309The default baud rate of the PBA31309 is 115200 bit/s. If another baud rate is needed it can bechanged by the customer. Changing the UART baud rate can be performed in two ways. Either the newbaud rate is stored in the EEPROM of the module during product manufacturing or the baud rate istemporary changed by the host in runtime.10.2.1 Change of baud rate in product manufacturingStep Command/response Description1 AT+JRES Send software Reset to the module ROK Make sure the module respond with ROK2 AT+JRBD Read BD-data+RRBDRES=083C0E19030000008A0080BA8C01BF02067E981F598740FA1218800003040506440C1002040001102404F2F8FE04B90006000000000000000000The module will respond with the complete BD-data.
