card Requests
The Notecard provides a number of requests that can be used to
configure the behavior of the Notecard, its pins, its use of GPS and
accelerometer data, and to query the state of the Device, its network connection
and peripherals. All of these requests begin with the card prefix.
card.attn CellCell+WiFiLoRaWiFi
Configure hardware notification from the Notecard to MCU host. Note: Requires a connection between the notecard ATTN pin and a GPIO pin on the host MCU.
See
card.attnin action as part of the Low-Power Digital Signage, Valve Monitor, and Flow-Rate Monitor accelerator projects.
mode
string
A comma-separated list of one or more of the following keywords. Some keywords are only supported on certain types of Notecards.
"" CellCell+WiFiWiFi
Fetches currently pending events in the "files" collection.
"arm" CellCell+WiFiLoRaWiFi
Clear "files" events and cause the ATTN pin to go LOW. After an event occurs or
"seconds" has elapsed, the ATTN pin will then go HIGH (a.k.a. "fires"). If
"seconds" is 0, no timeout will be scheduled. If ATTN is armed, calling arm
again will disarm (briefly pulling ATTN HIGH), then arm (non-idempotent).
"auxgpio" CellCell+WiFiLoRaWiFi
When armed, causes ATTN to fire if an AUX GPIO input changes. Disable by using
-auxpgio.
"connected" CellCell+WiFiWiFi
When armed, will cause ATTN to fire whenever the module connects
to cellular. Disable with -connected.
"disarm" CellCell+WiFiLoRaWiFi
Causes ATTN pin to go HIGH if it had been LOW.
Passing both "disarm" and "-all" clears all ATTN monitors currently set.
"env" CellCell+WiFiLoRaWiFi
When armed, causes ATTN to fire if an environment variable changes on the
Notecard. Disable by using -env.
"files" CellCell+WiFiLoRaWiFi
When armed, will cause ATTN to fire if any of the "files" are
modified. Disable by using -files.
"location" CellCell+WiFiWiFi
When armed, will cause ATTN to fire whenever the Notecard GPS module makes
a position fix. Disable by using -location.
"motion" CellCell+WiFiWiFi
When armed, will cause ATTN to fire whenever the accelerometer
detects module motion. Disable with -motion.
"motionchange" CellCell+WiFiWiFi
When armed, will cause ATTN to fire whenever the card.motion,mode changes
from "moving" to "stopped" (or vice versa). Learn how to configure this feature
in this guide.
"rearm" CellCell+WiFiWiFi
Will arm ATTN if not already armed. Otherwise, resets the values of mode,
files, and seconds specified in the initial arm or rearm request
(idempotent).
"signal" CellCell+WiFiWiFi
When armed, will cause ATTN to fire whenever the Notecard receives a signal.
"sleep" CellCell+WiFiWiFi
Instruct the Notecard to pull the ATTN pin low for a period of time, and optionally keep a payload in memory. Can be used by the host to sleep the host MCU.
"usb" CellCell+WiFiLoRaWiFi
When armed, will enable USB power events firing the ATTN pin. Disable with
-usb.
"watchdog" CellCell+WiFiWiFi
Not an "arm" mode, rather will cause the ATTN pin to go from HIGH to LOW, then HIGH if the notecard fails to receive any JSON requests for "seconds." In this mode, "seconds" must be >= 60.
"wireless" CellCell+WiFiWiFi
Instruct the Notecard to fire the ATTN pin whenever the
card.wireless status
changes.
files
array (optional)
A list of Notefiles to watch for file-based interrupts.
seconds
int32 (optional)
To set an ATTN timeout when arming, or when using sleep.
NOTE: When the Notecard is in continuous mode, the seconds timeout is serviced by
a routine that wakes every 15 seconds. You can predict when the device will
wake, by rounding up to the nearest 15 second interval.
payload
base64 string (optional)
When using sleep mode, a payload of data from the host that the Notecard
should hold in memory until retrieved by the host.
start
boolean (optional)
When using sleep mode and the host has reawakened, request the Notecard to
return the stored payload.

noteUtilizing these pins requires a physical connection to each pin, separate from a connection to the Notecard's serial data interfaces.
mode
string
The AUX mode. Must be one of the following keywords. Some keywords are only supported on certain types of Notecards.
"dfu" CellCell+WiFiWiFi

See Using DFU Mode
for more information.
"gpio" CellCell+WiFiLoRaWiFi
Configure the Notecard for GPIO mode with AUX1 OFF, AUX2 as an output
LOW, AUX3 as an output HIGH, and AUX4 as an input. See
Using AUX GPIO Mode
for more information.
"led" CellCell+WiFiWiFi
When wiring LEDs to the Notecard's AUX pins (as is done when using monitor mode), use this mode along with the card.led API to manually enable/disable individual red, green, and/or yellow LEDs.
"monitor" CellCell+WiFiWiFi
If you plan to place your Notecard in an enclosure, monitor mode can be used to configure inputs and outputs typically placed on the faceplate of a device in order for a technician to test and monitor Notecard activity.
"motion" CellCell+WiFiWiFi
Supplement autonomous tracking with digital inputs and a status output. See Using AUX Motion Mode for more information.
"neo" CellCell+WiFiWiFi

"track-neo-monitor" CellCell+WiFiWiFi
Combines track and monitor modes while also supporting NeoPixel LEDs that
allow for monitoring Notecard activity. See the
neo-monitor mode
documentation for additional context.
"-" CellCell+WiFiLoRaWiFi
Resets the AUX mode to its default value ("off").
usage
array of strings (required for gpio mode)
An ordered list of pin modes for each AUX pin when in GPIO mode. The following values can be used on all Notecards:
"" to leave the pin unchanged.
"off" to disable the pin.
"high" to set the pin as a HIGH output.
"low" to set the pin as a LOW output.
"input" to set the pin as an input.
"input-pulldown" to set the pin as a pull-down input.
"input-pullup" to set the pin as a pull-up input.
And the following values can be used on Notecard Cellular, Notecard Cell+WiFi, and Notecard WiFi:
"count" to set the pin as an input (interrupt) that increments a counter for
each rising edge pulse on the pin. It is up to the device's designer to make
sure that the signal is either HIGH or LOW at any time, and is never left
floating.
"count-pulldown" Same as count usage, but a pull-down resistor internal to
the Notecard will automatically keep the pin from floating.
"count-pullup" Same as count usage, but a pull-up resistor internal to the
Notecard will automatically keep the pin from floating and falling edges of
pulses are counted.
seconds
int (optional)
When in gpio mode, if an AUX pin is configured as a count type, the
count of rising edges can be broken into samples of this duration.
Passing 0 or omitting this field will total into a single sample.
max
int (optional)
When in gpio mode, if an AUX pin is configured as a count type, the
maximum number of samples of duration seconds, after which all subsequent
counts are added to the final sample. Passing 0 or omitting this value will
provide a single incrementing count of rising edges on the pin.
start
boolean (optional)
When in gpio mode, if an AUX pin is configured as a count type, set to
true to reset counters and start incrementing.
gps
boolean (optional)
Deprecated
If true, along with "mode":"track" the Notecard supports the use of an
external GPS module.
This argument is deprecated. Use the
card.aux.serial request with a mode of "gps" instead.
rate
int (optional)
The AUX UART baud rate for debug communication over the AUXRX and AUXTX pins.
sync
boolean (optional)
This argument is not available on Notecard LoRa.
If true, for pins set as input by usage, the Notecard will autonomously
report any state changes as new notes in file. For pins
used as counter, the Notecard will use an interrupt to count pulses and will
report the total in a new note in file unless it has been noted in the
previous second.
file
string (optional)
This argument is not available on Notecard LoRa.
The name of the Notefile used to report state changes when used in conjunction
with "sync": true. Default Notefile name is _button.qo.
connected
boolean (optional)
If true, defers the sync of the state change Notefile to the next sync as
configured by the hub.set request.
limit
boolean (optional)
If true, along with "mode":"track" and gps:true the Notecard will disable
concurrent modem use during GPS tracking.
sensitivity
int (optional)
When used with "mode":"neo-monitor" or "mode":"track-neo-monitor", this
controls the brightness of NeoPixel lights, where 100 is the maximum
brightness and 1 is the minimum.
ms
int (optional)
When in gpio mode, this argument configures a debouncing interval. With a
debouncing interval in place, the Notecard excludes all transitions with a
shorter duration than the provided debounce time, in milliseconds. This interval
only applies to GPIOs configured with a usage of count, count-pulldown, or
count-pullup.
count
int (optional)
When used with "mode":"neo-monitor" or "mode":"track-neo-monitor", this
controls the number of NeoPixels to use in a strip. Possible values are 1,
2, or 5. See
Using Neo-Monitor Mode
for more information.
offset
int (optional)
When used with "mode":"neo-monitor" or "mode":"track-neo-monitor", this is
the 1-based index in a strip of NeoPixels that determines which single NeoPixel
the host can command. See
Using Neo-Monitor Mode
for more information.

{} means success.card.restore CellCell+WiFiLoRaWiFi
Performs a factory reset on the Notecard and restarts.
Sending this request without either of the optional arguments below will only reset the Notecard's file system, thus forcing a re-sync of all Notefiles from Notehub.
On Notecard LoRa there is no option to retain configuration settings, and providing
"delete": true is required. The Notecard LoRa retains LoRaWAN configuration
after factory resets.
delete
boolean (optional)
Set to true to reset most Notecard configuration settings. Note that this does
not reset stored Wi-Fi credentials or the
alternate I2C address
(if previously set) so the Notecard can still contact the network after a reset.
The Notecard will be unable to sync with Notehub until the ProductUID is
set again.
connected
boolean (optional)
Set to true to reset the Notecard on Notehub. This will delete and deprovision
the Notecard from Notehub the next time the Notecard connects. This also removes
any Notefile templates used by this device.
Conversely, if connected is false (or omitted), the Notecard's settings and
data will be restored from Notehub the next time the Notecard connects to
the previously used Notehub project.

}card.wifi Cell+WiFiWiFi
Sets up a Notecard WiFi to connect to a Wi-Fi access point.
noteWi-Fi updates cannot occur if you have changed a Notecard WiFi's connection
mode from periodic to continuous. If you have a Notecard WiFi in
continuous mode, you must change it using
a hub.set request before using
card.wifi.
ssid
string (optional)
The SSID of the Wi-Fi access point. Alternatively, use - to clear an already
set SSID.
password
string (optional)
The network password of the Wi-Fi access point. Alternatively, use - to clear
an already set password or to connect to an open access point.
name
string (optional)
By default, the Notecard creates a SoftAP (software enabled access point) under
the name "Notecard". You can use the name argument to change the name of the
SoftAP to a custom name.
If you include a - at the end of the name (for example "name": "acme-"),
the Notecard will append the last four digits of the network's MAC address (for
example acme—025c). This allows you to distinguish between multiple Notecards
in SoftAP mode.
org
string (optional)
If specified, replaces the Blues logo on the SoftAP page with the provided name.
start
boolean (optional)
Specify true to activate SoftAP mode on the Notecard programatically.

View the last known network state, or customize the behavior of the modem. Note: Be careful when using this mode with hardware not on hand as a mistake may cause loss of network and Notehub access.
mode
string
Network scan mode. Must be one of:
"-" to reset
to the default mode.
"auto" to perform automatic band scan mode (this is the default mode).
"m" to restrict the modem to Cat-M1.
"nb" to restrict the modem to Cat-NB1.
"gprs" to restrict the modem to EGPRS.
apn
string
Access Point Name (APN) when using an external SIM. Use "-" to reset to the
Notecard default APN.
method
Used when configuring a Notecard to failover to a different SIM.
"-" resets the Notecard to the default method.
"dual-primary-secondary" will attempt to register with the internal SIM first,
then failover to the external SIM.
"dual-secondary-primary" will attempt to register with the external SIM first,
then failover to the internal SIM.
"primary" will exclusively use the internal SIM.
"secondary" will exclusively use the external SIM.
hours
When using the method argument with "dual-primary-secondary" or
"dual-secondary-primary", this is the number of hours after which the Notecard
will attempt to switch back to the preferred SIM.
