Digi XBee LTE-M/NB-IoT Element
The XBee LTE-M/NB-IoT element is used to send data over a cellular network. This element is for using the Digi XBee3 Cellular LTE-M/NB-IoT cellular modem. This cellular modem communicates over UART using an AT command set. It takes several seconds to perform HTTP transactions, so it’s recommended to send data infrequently.
Given the high RAM usage of this element for storing HTTP packets, it’s only available on the following platforms:
- Arduino Mega
- NXP Rapid IoT
- Maxim MAX32630 Feather
- ESP32 and its variants
The XBee LTE-M/NB-IoT is a protocol element that can be imported into the Element Toolbox through the Add Element button located in the toolbox from the Embedded tab.
The following properties can be changed for the XBee LTE-M/NB-IoT element:
The name of the element.
UART Driver Instance
The UART driver instance to use.
NOTE: The chosen UART driver instance must be exclusive to the cellular modem. It must not be shared with debug print data.
GPIO Driver Instance
The chosen GPIO driver instance to use.
The GPIO pin that resets the modem. This pin will automatically be used to reset the modem on startup. Set to
ATMO_GPIO_NO_PIN if unused.
Destination Phone Number
Phone number used for SMS messages. This should be formatted with digits only (no spaces or dashes), with an optional
+ entered at the beginning of the number for the country code.
The following triggers are available to execute events from within the XBee LTE-M/NB-IoT element:
Execute an event when the source element connected to the XBee LTE-M/NB-IoT triggers.
Execute an event after an SMS message is sent.
The following abilities are available for the XBee LTE-M/NB-IoT element when its source element triggers:
Trigger the element(s) that follow the XBee LTE-M/NB-IoT element.
Send an SMS to the phone number specified in the element’s properties.
