No, I'm not using tuya. Only TCP Server, TCP Client and MQTT some of them in the same time that's why is important this firmware.

if you not use Tuya , you can use old firmware, no problem.
because new firmware have different data structure, so you need to use AT-Link tool to eraser CPU , re download BOOTLOAD hex file , then download BIN file will be ok. i have tested newest firmware, without any problem.

No problem. I will use AT-Link tool and make every step necessary but with new firmware I can use TCP Server and MQTT same time. With old firmware cannot use same time. Another reason I don't want to be behind with updates so if you could send the BOOTLOAD hex file I'll appreciate it. Thank you.

here is BOOTLOADER HEX file for KC868-COLB.
open your metal box, make sure your CPU chip is AT32F403AVGT7, if you not sure, you can take a photo of your biggest CPU chip on PCB.

Ok. So I reflashed the bootloader and downloaded latest firmware but still the same problem. Why it has the port 80 and not the 4196 as all other devices? I think there is some collusion there.
