- Add ID? command to firmware: server responds 'SylDa_Server', client 'SylDa_Client' - Add tools/pio_upload_port.py POST-script that queries connected ESP32s - Remove hardcoded upload_port from platformio.ini - Script logic: 1 ESP32 → use directly, 2+ → ID? query, no match → prompt user - Requires pyserial for serial queries (graceful fallback if missing)

"""POST-script: auto-detect upload_port by querying connected ESP32s.
|
|
|
|
Each ESP32 running SylDa firmware responds to the serial command "ID?"
|
|
with either "SylDa_Server" or "SylDa_Client". This script scans
|
|
/dev/serial/by-id/ for Espressif devices, queries each one, and sets
|
|
UPLOAD_PORT for the matching environment.
|
|
|
|
If no device responds (e.g. first flash), the user is prompted to
|
|
select a port manually.
