UART connection between CC3200 and external device

Other Parts Discussed in Thread: CC3200

Hello,

I am trying to connect the eZ430RF2500 and the CC3200 using the uart interface. In the eZ430RF2500 I have the wireless sensor monitor code running with a few modifications and in the cc3200 I have the uart_demo code running with baud rate set as 9600.

But i dont know how to connect both of them. In the eZ430RF2500  have the P3.4 as the Transmitter and the P3.5 as the receiver. Baud rate is set as 9600 for both. Both have been tried and tested at that baud rate.

This I found in the CC3200 SimpleLink™ Wi-Fi® and IoT Solution with MCU LaunchPad Hardware and it says that the transmit and receive are the 4th and the 3rd pin. Also how do i connect the jumpers on J6 and J7.

Also in PinMuxConfig(); function in the CC3200 it says-

//
// Configure PIN_55 for UART0 UART0_TX
//
MAP_PinTypeUART(PIN_55, PIN_MODE_3);

//
// Configure PIN_57 for UART0 UART0_RX
//
MAP_PinTypeUART(PIN_57, PIN_MODE_3);


So where do I connect the transmit and receive pin of the eZ430RF2500 on the CC3200.

    Basically I have to connect exernal device via UART interface to the CC3200, but I am unable to figure out which is the Tx and Rx pin in the CC3200. Do I have to remove the jumpers on J6 and J7?
    I don't have to display the value on the Teraterm software. I have to take the values from the external device via UART and then save the values received in a variable in CC3200. then i have to email those specific values. So I have to have one UART to receive the values and the other  UART which can run the email example code.

    So how do make the connections on the CC3200 so that from the external device i am able to receive values from  one UART and the other UART is used to display values on the teraterm.

    I am using the CC3200 Launchxl
