KC868-A16 rev1.6 firmware

[maurus44]

Hello,
I am using a KC868-A16 board (REV: 1.6) and I would like to confirm which firmware is correct for this device.
I have been flashing firmware using the ESP32 Flash Download Tool (v3.9.2). So far, I have tested the following firmware versions:

• KCS_A16V3_V3.24.3 → I was not able to access the controller after flashing
  
• KCS_KC868_A16_V2.2.4 → I could access the controller, but the input table was incomplete / partially missing
  

At the moment, I am using:

• KC868_A16_V1.0.10 → this version works, and I can access the controller
  

My question is:
Am I using the correct firmware for KC868-A16 REV: 1.6, or is there a newer recommended version that is fully compatible?
Thank you in advance for your help!
