- Introduced a new method `formatIsoTimestampForMqtt` to centralize ISO-like timestamp formatting for MQTT messages, applying timezone preferences.
- Updated `buildStatusMessage`, `buildPacketJSON`, `buildPacketJSONFromRaw`, and `buildRawJSON` methods to utilize the new timestamp formatting function, improving code clarity and reducing redundancy.
- Adjusted `publishStatusToSlot` and `publishStatus` in MQTTBridge to use the new timestamp formatting method, ensuring consistent timestamp handling across status messages.
- LilyGo T-LoRa V2.1 observer envs: set ESP32_CPU_FREQ=240 and
MQTT_TASK_STACK_SIZE=16384 only for those targets so classic ESP32
TLS + JWT connect fits the FreeRTOS task; other boards keep the
default 8192 B unless overridden.
- MQTTBridge: use large JSON stack fallbacks only for PSRAM builds when
heap-backed buffers may be null; non-PSRAM paths use the inline
member buffers only, cutting peak stack in status/packet/raw publish.
- MQTTBridge.h: update the StaticJsonDocument comment (no longer refers
to an 8 KiB MQTT task stack).
Implemented a new function to strip surrounding quotes from strings in TxtDataHelpers, enhancing string manipulation capabilities. Updated CommonCLI to handle MQTT origin configuration, allowing for both setting and clearing of the mqtt.origin preference. This change improves the flexibility of MQTT origin management in the CLI.
Updated the MQTT message structure to add a new field for repeat status, allowing the indication of forwarding status as "on" or "off". This change includes modifications to the MQTTMessageBuilder and related documentation to reflect the new parameter. Additionally, updated CLI command documentation to clarify flooding behavior in different firmware versions.
Updated MyMesh implementations in simple_repeater and simple_room_server to set mqtt_origin to an empty string, allowing the effective origin to follow node_name during publishing. Introduced new functions in MQTTBridge to manage effective origin retrieval and refresh from preferences, ensuring consistent behavior across MQTT operations. This change simplifies the origin management and enhances clarity in the codebase.
Enhanced the MQTTBridge error handling by adding several missing error codes for Wi-Fi and TLS errors, improving the clarity of error reporting during connection issues. This update includes new cases for group cipher mismatch, invalid PMKID, and TLS handshake failures, among others.
Refactor the MQTTBridge to implement enhanced QoS handling for publish operations. Introduce retry mechanisms for QoS0 packets, allowing for transient failures to be retried with a delay. Update publish methods to return success status, improving error handling and logging. Additionally, adjust the packet queue processing to accommodate new retry logic and ensure better message delivery control.
Implement a new method `formatRadioDiagReply` in MyMesh to format and return radio diagnostic information. Update CommonCLI to handle the new command for retrieving radio diagnostics. Enhance the Dispatcher class with a radio watchdog feature to monitor and recover from silent radio states. Introduce new error flags and methods in the Dispatcher and RadioLibWrapper classes to support these diagnostics, improving overall radio management and troubleshooting capabilities.
This commit introduces a new `reconnect` method in the `PsychicMqttClient` class, allowing for re-establishing a connection to the MQTT broker without needing to disconnect first. The method checks if the client is initialized, updates the configuration if necessary, and attempts to reconnect, enhancing the overall connection management. Additionally, the MQTT slot management has been updated to support up to 6 configurable slots, improving flexibility in connection handling.
- Updated pressure window and threshold constants to differentiate between critical and moderate memory pressure scenarios.
- Enhanced recovery logic to trigger based on specific pressure conditions, improving responsiveness to memory fragmentation.
- Added explicit calls to recreate analyzer client objects during recovery, ensuring proper setup after memory management actions.
These changes aim to optimize memory handling and recovery processes in the MQTTBridge, enhancing overall stability.
- Improved NTP sync logic by implementing retry attempts for NTP updates, enhancing reliability on various hardware.
- Added a fallback mechanism to use ESP32's built-in SNTP if NTPClient fails, ensuring time synchronization continuity.
- Updated the handling of epoch time validation to ensure it meets a minimum threshold before proceeding with time updates.
- Streamlined the process of setting the system timezone and updating the RTC clock, improving overall time management efficiency.
- Updated the logic for JWT token timestamp validation to allow reconnection if the system clock is set, even when NTP sync is not confirmed. This change prevents unnecessary connection blocks after a successful NTP sync at boot.
- Introduced a check to determine if the system clock is clearly set, improving the robustness of the connection maintenance process.
- Introduced a new method `runCriticalMemoryCheckAndRecovery()` to streamline memory checks and recovery processes.
- Added member variables to track fragmentation pressure and the last critical check run time.
- Removed redundant critical memory check logic from `mqttTaskLoop()` and `loop()`, enhancing code clarity and maintainability.
- Improved logging and pressure tracking for better diagnostics during memory management.
- Added new member variables to track WiFi connection state and implement exponential backoff for reconnection attempts.
- Refactored WiFi monitoring logic into a dedicated function to streamline the mqttTaskLoop.
- Introduced fragmentation recovery logic to handle memory pressure more effectively, ensuring MQTT clients are recreated when necessary.
- Reset reconnect backoff attempts upon successful connection to the main broker.
These changes aim to improve the stability and performance of the MQTTBridge under varying network conditions.
- Introduced PSRAM-aware memory allocation functions (`psram_malloc` and `psram_free`) to optimize memory usage on ESP32 boards with external RAM.
- Updated MQTTBridge initialization to allocate JWT token buffers and raw data storage in PSRAM when available.
- Enhanced FreeRTOS queue creation to utilize PSRAM for storage, improving memory efficiency.
- Implemented dynamic allocation for JSON buffers in PSRAM during status publishing and packet handling, reducing stack usage.
- Ensured proper memory cleanup for PSRAM allocations in the `end` method to prevent memory leaks.
This update aims to enhance performance and stability in memory-constrained environments by leveraging available PSRAM resources.
- Implemented PSRAM availability checks and logging to assist in debugging memory fragmentation on boards with external RAM.
- Enhanced logging to provide detailed information about PSRAM size, free memory, and initialization status.
- Updated platformio.ini files across multiple variants to remove obsolete mbedTLS configuration flags, streamlining the build process.
- Added memory debugging features to log heap usage and fragmentation recovery for MQTT clients.
- Introduced `recreateMqttClientsForFragmentationRecovery()` to manage MQTT client lifecycles and reduce memory fragmentation.
- Updated critical memory checks to log detailed heap statistics and active MQTT client counts.
- Included new debug logging for memory status every 60 seconds when memory debugging is enabled.
This update aims to improve stability and performance in memory-constrained environments.
- Main broker: only allocate _mqtt_client when custom broker configured
(analyzer-only saves one PsychicMqttClient). Reconnect main broker after
forced disconnect with 30s throttle; set last_attempt on disconnect so
throttle applies and avoids reconnect storms on flaky WiFi.
- Analyzer clients: call disconnect() when WiFi transitions to disconnected
so ESP-IDF frees MQTT buffers (it does not free on WiFi drop). Reduces
fragmentation and Max drop after disconnect/reconnect cycles.
- get wifi.status: report WiFi uptime (Xd Xh Xm Xs) when WITH_MQTT_BRIDGE.
Track connect time in bridge; backfill when already connected at first check.
- get mqtt.status: show msgs on/off, broker (connected/disconnected/n/a),
analyzer US/EU (connected/disconnected/off), and queue count.
Note: PsychicMqttClient change (register event only on first client creation)
belongs in the library repo if committed separately.
- Updated comments to specify that the Dispatcher owns the packet memory and should handle freeing.
- Removed unnecessary calls to free queued packets in the MQTTBridge, ensuring only references are discarded.
- Enhanced code clarity regarding packet lifecycle management in the end and processPacketQueue methods.
- Introduced `getPacketsRecvErrors()` method in `Dispatcher` to track receive errors.
- Updated `buildStatusMessage()` in `MQTTMessageBuilder` to include `recv_errors` parameter.
- Modified `publishStatus()` in `MQTTBridge` to retrieve and send receive error statistics.
- Adjusted `RadioLibWrappers` to override `getPacketsRecvErrors()` for consistency.
