Extract the inline cursor-walk in handleRegionCmd into file-local
helpers (skipSpaces, rtrimSpaces, takeToken, splitNameJump,
processRegionDefSegment), grouped immediately above the consumer.
Behavior is identical; addresses PR #2540 review feedback on
readability.
Tighten the region def docs: collapse five Note callouts into three
grouped paragraphs (Behavior / Existing regions / Limits), add a
case-sensitivity caveat plus an error example, note the cursor reset
between split commands, and use generic placeholder names.
Modified the alert PSK command handling to only respond when the sender timestamp is zero, ensuring that the PSK is processed exclusively from the serial command line. This change enhances security and clarity in the command processing logic.
- 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.
Remove the hardcoded BLE_PIN_CODE build flag from the Heltec_E290_companion_ble
environment. The presence of BLE_PIN_CODE prevents the unit from operating as a
USB companion. Commenting it out allows dynamic PIN generation and enables USB
companion functionality.
- Added guidance for using a single active WSS broker preset in the T-LoRa V2.1–1.6 MQTT observer environments, clarifying that dual TLS sessions may fail due to memory constraints.
- Updated partition table descriptions to reflect the new recommendation for the `LilyGo_TLora_V2_1_1_6_repeater_observer_mqtt` and `LilyGo_TLora_V2_1_1_6_room_server_observer_mqtt` targets.
- Enhanced platformio.ini comments to emphasize the single broker usage and its implications for memory management.
- 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).
Updated the alert PSK implementation to remove base64 support, now requiring a 32-character hex format for private channel secrets. Adjusted related CLI commands, error messages, and internal handling to ensure consistency with the new format. This change enhances clarity and aligns with the mobile app's "Share Channel" output. Relevant updates made across multiple files, including documentation and preference handling.
