Configuration Reference

GLIDER stores configuration in non-volatile memory (NVS), so settings survive power cycles and reboots. You can change configuration through either console:

• AT console: AT$CONFIG="<module>","<key>",<value>
• RTT console (Zephyr shell): <module> config <key> <value>

After making changes, always save them to flash:

AT&W

This persists the new values and reboots the device. To wipe everything back to factory defaults:

Listing configuration

Goal	AT command	Shell command
List every module	AT$CONFIG?	config show
List one module	AT$CONFIG="<module>"	<module> config show
Read one key	AT$CONFIG="<module>","<key>"	<module> config show <key>
Show full schema	AT$CONFIG=?	-

The schema (AT$CONFIG=?) reports each key's type, range, default and a one-line description, useful for discovery.

Global app settings

These keys apply to the whole device.

Key	Type	Range	Default	Description
interval-sample	int (s)	5–3600	60	How often the firmware reads sensors and evaluates alarms.
interval-send	int (s)	30–86400	300	How often the firmware encodes a CBOR payload and uplinks it.
downlink-wdg-interval	int (s)	0–1209600	129600 (36 h)	Downlink watchdog. If the cloud sends no downlink within this period, the device reboots. 0 disables the watchdog.

Example

app config interval-sample 30
app config interval-send 120

Digital inputs

GLIDER has two galvanically isolated digital input channels (CH1 and CH2). Each channel can run in one of three modes:

Mode	Behavior
disabled	The channel is powered off: no counting, no events.
counter	Selected edges (rising / falling / both) increment counters. Counters are sent in every CBOR payload.
event	Each edge produces a timestamped event. Events are streamed in the next CBOR payload (up to 64 per channel, per send cycle).

Per-channel keys

The same keys exist for both channels, prefixed with 1- (CH1) or 2- (CH2):

Key	Type	Range	Default	Description
<n>-mode	enum	disabled / counter / event	disabled	Channel mode.
<n>-active-duration	int (ms)	0–60000	100	Minimum time the input must stay active (rising edge debounce).
<n>-inactive-duration	int (ms)	0–60000	100	Minimum time the input must stay inactive (falling edge debounce).
<n>-cooldown-time	int (ms)	0–60000	10	Minimum time between two registered transitions.
<n>-counter-edge	enum	rising / falling / both	both	Which edges increment the counter (only used in counter mode).
<n>-event-type	enum	activation / deactivation / both	both	Which transitions create events (only used in event mode).

Example - count pulses on CH1

inputs config 1-mode counter
inputs config 1-counter-edge rising
inputs config 1-active-duration 5
inputs config 1-inactive-duration 5
AT&W

This counts every rising edge on CH1 as long as the input stays high for at least 5 ms (and low for at least 5 ms between pulses).

Thermometer slots (therm)

Eight independent slots, one ROM code per slot. Empty slots are skipped in the cloud payload.

Key	Type	Size	Default	Description
1 … 8	hex	8 bytes	0x00…	DS18B20 ROM serial bound to that slot. 0x00… = empty.

tip

In practice you should not edit these by hand. Use therm scan --save to discover and bind sensors automatically. See External Temperature Sensors.

Alarms

Up to 32 independent alarm rules can be configured. Each rule watches one thermometer slot and toggles between active and inactive based on a threshold with hysteresis:

• The rule activates when temperature ≥ threshold.
• The rule deactivates when temperature ≤ threshold − hysteresis.

Each transition is recorded in the alarm events buffer and uploaded with the next CBOR payload.

The same four keys exist for every rule, prefixed with <n>- (1-32):

Key	Type	Range	Default	Description
<n>-enabled	bool	-	false	Master switch for the rule. When false, the other keys for this rule are hidden.
<n>-therm	int	1–8	1	Which thermometer slot the rule watches.
<n>-threshold	float (°C)	−55–125	50	Activation threshold.
<n>-hysteresis	float (°C)	0–50	5	Deactivation offset below the threshold.

Example - alarm on slot 1 if it exceeds 30 °C

alarm config 1-enabled true
alarm config 1-therm 1
alarm config 1-threshold 30
alarm config 1-hysteresis 5
AT&W

When slot 1 reads ≥ 30 °C the firmware fires the alarm; it clears again when the reading drops to ≤ 25 °C.

Saving and resetting

Action	Command
Save and reboot	AT&W
Factory reset (wipe everything)	AT&F
Reboot without saving	AT$REBOOT

caution

AT&F is destructive: every configured slot, alarm rule and interval is reset to factory defaults. There is no undo.
