I've got problems flashing my B16. Tried address 0x10000 and then 0x0. Getting this error below always. Why?
Quote:8-download data fail
Tips:
Maybe communication instability caused this error, you can try to reduce the baud rate of download.

take a photo of your controller and screen photo of download tool.
download firmware, use 0x0 address.
RE: "KCS" v3.9.4 firmware BIN file download - ck1 - 07-09-2025
Yes, I have used 0x0 address.
This is what I get ... as in the attachment.

which board model you are using?
RE: "KCS" v3.9.4 firmware BIN file download - ck1 - 07-09-2025
I am using B16, the relay version. Is there another model?
So far no success flashing it with KCS v3. I think I will just use ESPHome instead.

1. power off B16
2. hold on DW (download) button, don't move your finger.
3. power on of B16
4. release your finger.
5. Then B16 enter bootloader mode. download firmware again.

Oh, thank you. I've learned to go to bootloader from your message!
One more question:I have bought a few HAv2. If I only use YAML file and not KCSv3, can I still use these HAv2 on B16's RS485?
I already viewed E16T with HAv2 here. I just want to confirm I can do the same with B16 and HAv2.
RE: "KCS" v3.9.4 firmware BIN file download - admin - 07-09-2025
sure, it's ok, you can config by ESPHome, only need to use RS485 port.
