AWR1642BOOST: How can I connect AWR1642 to wifi?

Part Number: AWR1642BOOST
Other Parts Discussed in Thread: AWR1642,

I'm testing driver vital signs with AWR1642.
And, i would like to send both a breath rate and a heart rate to the my server.
I would like to connect with a wifi module such as esp8266 and communicate with the server.
What should I do?

  • Hi,
    AWR1642 provides multiple interfaces to send output data out, it can be UART/SPI/CAN.
    So you need to use one of this interface with your Wi-Fi module where AWR1642 will send the output data over this interface and WiFi module can read that data over the same interface and send it to server wirelessly.

    These interface lines come on J5/J6 header of AWR1642BOOST EVM which you need to connect with a wire.

    Many of points on J5/J6 may not be populated so you better refer AWR1642BOOST schematic to find out if you need to solder any resistor on those points.

  • I am trying to connect to a computer without a usb cable before connecting to a wifi.
    1. R169 and R166 are connected.
    2. R128 and R129 disconnected.
    3. I connected the pins 5 and 7 of J6 to the computer.
    4. connected R26.
    5. I connected J5's 9th pin to my computer.

    However, the 1642 can not be connected to the computer.

  • Reading data through AR_MSS_LOGGER was successful.
    However, sending config value fails.

    This is the config value I sent mmwave.
    The baud rate is 115200bps and the format is ASCII.

  • Hi,
    Resistors changes are correct. When you say AR_MSS_LOGGER was successful that means you are getting UART from AWR1642 device to PC with the correct data.
    With these setting you should see the data over RS232 UART as well.

    RS232Rx/Tx: could you try putting a breakpoint in the 'UartSci_ISR' function of UARTSci.c which should hit whenever you recieve any data over this UART interface. Assuming UART is initialized and configured
    Or check for this register SCIFLR: 0xFFF7 E51C [9th bit: The receiver sets this bit to indicate that the SCIRD contains new data and is ready to be read by the CPU or DMA].
