  • Page 75 The TP reading may not be calibrated. To compensate for this you can determine an offset to use in the equations above as follows: With the XBee Cellular Modem not powered, allow it to sit at room temperature for 15 - 20 minutes. Power the device and immediately read the TP command. Convert the TP reading from hex format to decimal and subtract the result from the actual room temperature.

    Based on the results of your thermal testing you may find it is advisable or required to implement a method of dissipating excess heat. This section explains how to employ a heat sink on top of the XBee Cellular Modem.

  • Page 77: Add A Fan To Provide Active Cooling

    Another option for heat mitigation is to add a fan to your system to provide active cooling. You can use a fan instead of or in addition to a heat sink. The XBee Cellular Modem offers a fan control feature on I/O pin DIO11 (pin 7).

    GSM 03.38 character set. Because this character set only provides 7 bits of space per character, the XBee Cellular Modem ignores the most significant bit of each octet in an SMS transmission payload.

    Modes Select an operating mode Select an operating mode The XBee Cellular Modem interfaces to a host device such as a microcontroller or computer through a logic-level asynchronous serial port. It uses a UART for serial communication with those devices.

  • Page 83: Transparent Operating Mode

    In Bypass mode, the device acts as a serial line replacement to the cellular component. In this mode, the XBee Cellular Modem exposes all control of the cellular component's AT port through the UART. If you use this mode, you must setup the cellular modem directly to establish connectivity. The modem does not automatically connect to the network.

  • Page 84: Leave Bypass Operating Mode

    AT commands. When you want to read or set any parameter of the XBee Cellular Modem using this mode, you have to send an AT command. Every AT command starts with the letters AT followed by the two characters that identify the command and then by some optional configuration values.

  • Page 85: Troubleshooting

    Multiple AT commands You can send multiple AT commands at a time when they are separated by a comma in Command mode; for example, ATNIMy XBee,AC<cr>. The preceding example changes the NI (Node Identifier) to My XBee and makes the setting active through AC (Apply Changes).

The device's serial port can communicate: Through a 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 93: Serial Buffers

    Serial buffers Serial buffers The XBee Cellular Modem maintains internal buffers to collect serial and RF data that it receives. The serial receive buffer collects incoming serial characters and holds them until the device can process them. The serial transmit buffer collects the data it receives via the RF link until it transmits that data out the serial or SPI port.

  • Page 95: Spi Communications

    SPI communications SPI communications The XBee Cellular Modem supports SPI communications in slave mode. Slave mode receives the clock signal and data from the master and returns data to the master. The following table shows the signals that the SPI port uses on the device.

  • Page 96: Full Duplex Operation

    This allows the SPI slave to alert the SPI master that it has data to send. In turn, the SPI master is expected to assert SPI_SSEL and start SPI_CLK, unless these signals are already asserted and active respectively. This, in turn, allows the XBee Cellular Modem SPI slave to send data to the master.

  • Page 97: Low Power Operation

    By default, Digi configures DIO8 (SLEEP_REQUEST) as a peripheral and during pin sleep it wakes the device and puts it to sleep. This applies to both the UART and SPI serial interfaces.

  • Page 98: Force Uart Operation

    Data format SPI only operates in API mode 1. The XBee Cellular Modem does not support Transparent mode or API mode 2 (which escapes control characters). This means that the AP configuration only applies to the UART, and the device ignores it while using SPI.
