Adjust the command handling in CommonCLI_Observer to prioritize the
more specific "timezone.offset" check before the general "timezone"
check. This change prevents incorrect responses when querying the
timezone offset, improving the clarity and correctness of command
responses.
Enhance the command handling in CommonCLI_Observer to clarify the
compilation behavior under different configurations. Additionally,
optimize memory pressure checks in MQTTBridge to reduce unnecessary
heap walks, improving performance during sustained memory pressure.
This change ensures that publishes are skipped only when necessary,
enhancing overall stability.
Port the neighbors CLI from mqtt-bridge-implementation-flex:
- set mqtt.neighbors on|off - enable/disable periodic publishing
- set mqtt.neighbors.interval <h> - 12-336 hours (rejected, not clamped), stored ms
- get mqtt.neighbors - "on"/"off"
- get mqtt.neighbors.interval - "> <hours> hours (<ms> ms)" (ceiling division)
Both gated on WITH_MQTT_NEIGHBORS with a WITH_MQTT_BRIDGE stub replying
"Err - not supported (requires PSRAM)" on non-PSRAM builds. Handlers only write
prefs + savePrefs() — the mesh loop reads them live, so no bridge restart and no
direct bridge/MyMesh call (matches flex).
Token ordering preserved: SET tokens keep their trailing space so the shorter
"mqtt.neighbors " can precede "mqtt.neighbors.interval "; GET tokens have no
trailing space so the longer ".interval" is tested first.
UTF-8 em-dashes (U+2014) inside MQTT_DEBUG_PRINTLN / CLI reply strings
render as mojibake ("aEUR"-style, e.g. cooperative stop garbles) on
consoles that don't decode UTF-8. Replace the em-dashes in printed
strings with ASCII '-'. Comments are intentionally left unchanged (they
never reach the console; rewriting them would be needless churn in a
merge-sensitive file).
Verified on V3: the stop message now emits pure ASCII -- zero non-ASCII
bytes in the boot+stop console capture.
Include detailed instructions for local testing of observer and WiFi
functionality without hardware. Document the use of a mock backend and
Wokwi ESP32-S3 simulation for easier development and testing.
Enhance the MQTT implementation documentation to improve developer
experience and facilitate testing workflows.
Introduce a web configuration portal for easier node management and
provisioning without serial CLI. Enhance MQTT functionality with
improved IATA code validation, dynamic slot management, and
background NTP synchronization. Update web UI elements for better
user experience and security notes regarding open AP usage.
The 30s "MQTT: Memory" line was useful during the outbox/sync-publish
investigation but is spam for production. Gate the periodic logMemoryStatus()
call in the MQTT task loop behind MQTT_MEMORY_DEBUG (a dedicated diagnostics
flag, not enabled by plain MQTT_DEBUG or production builds) and stop the
heltec_v3 variant from force-enabling MQTT_MEMORY_DEBUG on its observer_mqtt
envs (now commented out to match heltec_v4). logMemoryStatus() itself is kept
intact for opt-in debugging.
Expose the same data on demand via a new `get mqtt.stats` CLI command backed by
MQTTBridge::formatMqttStatsReply(): free/max heap, queue depth, outbox total,
and per-slot publish ok/err counts (1-based, matching the msgs: line). Fits the
160-byte reply buffer at 6 slots; returns "(bridge not running)" when down.
Reverts merge ae045395 (feat/flex-ipv6, PR #25). Enabling IPv6 joins the
device into IPv6 multicast/ND processing; on multicast-heavy LANs (e.g.
with a Thread/Matter border router advertising a ULA prefix) inbound
bursts land in dynamic WiFi RX buffers in internal heap. Measured on a
Station G2 with 4 WSS brokers: min-free floor dropped 36 KB -> 18 KB,
largest free block pinned below the 16 KB publish threshold for minutes
at a time, 523 dropped publishes in 15 minutes. With IPv6 disabled the
floor and max-alloc recovered and publish skips stopped.
The feature only fed the wifi.status display line — no transport uses
IPv6 (all brokers connect over IPv4), so the fleet risk (network-
dependent degradation on unknown home LANs) buys nothing. Revisit after
the Arduino core 3.x / IDF 5.x move if IPv6 transport is ever needed;
the branch remains at feat/flex-ipv6.
Kept from the merge: the wifi.status uptime append now computes the
actual remaining space in the 160-byte reply buffer instead of assuming
a hardcoded 128, fixing a latent overflow of the snprintf bound.
Refactored the handling of observer-related settings by moving them from
NodePrefs to a new MQTTPrefs structure. This change centralizes MQTT,
WiFi, timezone, SNMP, and alert configurations, improving code organization
and maintainability. The new structure allows for better separation of
concerns and prepares the codebase for future enhancements.
Refactored the CommonCLI class to separate observer-related command
handling into CommonCLI_Observer.cpp. This change improves code
organization and maintainability by isolating MQTT, WiFi, and other
observer-specific commands from the main CLI logic.
