EDL-1 not logging or showing live data on the app

Hi everyone,

I have an ECUMASTER EDL-1 connected to an EMU Black.

The main problem is that the EDL never starts logging.

Current setup:

  • EMU Black FW 2.175
  • EMU Black Client 2.175
  • EDL-1 FW 1.27

What works:

  • EDL powers up normally.
  • Green LED stays solid.
  • Bluetooth works and connects.
  • EMU Black detects the device as “ECUMASTER logger EDL-1”.
  • “Set Datalogger Time” works successfully.
  • ECU is synchronised and running normally.
  • EDL creates the EDL-INFO file on the SD card.

What does NOT work:

  • The EDL never starts logging.
  • Green LED never starts flashing.
  • No log files are created on the SD card.
  • SD card only contains EDL-INFO.
  • eDash shows no live data.

Checks already performed:

  • Dedicated 12V supply to EDL.
  • Ground verified.
  • RS232 wiring verified multiple times.
  • EDL RX/TX connected to EMU Black pins 11 (TXD) and 24 (RXD).
  • SD card formatted FAT32.
  • ECU firmware updated from 2.169 to 2.175.
  • Different Bluetooth devices tested.

Additional information:

  • Using a SanDisk 32GB SD card formatted to FAT32.
  • The card is not completely rejected by the logger because EDL-INFO is created successfully every time.
  • However, no log files are ever generated.

Has anyone seen an EDL-1 that is detected correctly by EMU Black but never enters logging mode and never creates any log files?
