PlugStream Firmware 1.53.4

Bug Fixes

  • ocpp: execute the offline journal CREATE TABLE instead of only preparing it (38254ab)
  • security: stop logging the presigned firmware URL in full (f8f1439)
  • sensor: bound journal recovery so a broken database cannot burn the CPU (5aec47d)
  • sensor: detect a slow journal, not just a broken one, and say so remotely (2318d52)
  • sensor: keep the journal file small - littlefs charges every commit for it (02fef3b)
  • ocpp: make the boot-recovery SQL executable on the device it ships to (1a99b6a)

Features

  • ble: enable BLE 5 (2M PHY) and link encryption, keep BLE always on (c8ddf29)
