The device can communicate through its serial port with: Through logic and voltage compatible universal asynchronous receiver/transmitter (UART). Through a level translator to any serial device, for example, through an RS-232 or USB interface board.

  • Page 35: Spi Communications

    Operation SPI communications You can configure the UART baud rate, parity, and stop bits settings on the device with the BD, NB, and SB commands respectively. For more information, see Serial interfacing commands. In the rare case that a device has been configured with the UART disabled, you can recover the device to UART operation by holding DIN low at reset time.

  • Page 36: Select The Spi Port

    Operation SPI communications SPI mode is chip to chip communication. We do not supply a SPI communication option on the device development evaluation boards. Select the SPI port On the through-hole devices, you can force SPI mode by holding DOUT/DIO13 low while resetting the device until SPI_ATTN asserts.

  • Page 37: Serial Buffers

    Operation Serial buffers If the output buffer is empty, the SPI serializer transmits the last valid bit repeatedly, which may be either high or low. Otherwise, the device formats all output in API mode 1 format, as described in operation. The attached host is expected to ignore all data that is not part of a formatted API frame. Serial buffers The XBee Wi-Fi RF Module maintains internal buffers to collect serial and RF data that it receives.

  • Page 38: Cts Flow Control

    Operation The Commissioning Button CTS flow control The FT command allows you to specify how many bytes of data can be queued up in the serial transmit buffer before the device asserts CTS low. The serial receive buffer can hold up the 2100 bytes, but FT cannot be set any larger than 2083 bytes, leaving 17 bytes that can be sent by the host before the data is dropped.

  • Page 200: Rework

    Manufacturing information Rework Note The best practice is to use a “no clean” solder paste to avoid the issues above and ensure proper module operation. Rework CAUTION! Any modification to the device voids the warranty coverage and certifications. Rework should never be performed on the module itself. The module has been optimized to give the best possible performance, and reworking the module itself will void warranty coverage and certifications.
