Overvoltage and Undervoltage Testing Issue with BMS_C1 Board about bms-c1 HOT 6 OPEN

Okay I will raise a new issue.
I closed the cutecom application before flashing. The error persists.

from bms-c1.

Thanks for posting this issue.

I could not reproduce the behavior with latest main firmware on a BMS C1 v0.3.3 board with 4s cells. Once the BMS goes into undervoltage state the TP6 stays at around 0V all the time and only goes up again after the battery voltage rises above the reconnect threshold.

Which firmware version did you use?

from bms-c1.

Thank you for the reply.

The firmware version is v23.0-0-g99d48b0.

Of the two boards only this board has this issue. The other board is working as intended.

Did you also try with the most recent firmware?

Also: If it appears only on one board, it may actually be a hardware issue.

Follow-up: Live Data Not Publishing, and Board Shutdown Issue with Latest Firmware

Issue:
I tried updating to the latest firmware version "v23.1-1-g55c2ea2-dirty," but encountered two issues:

Live data is not being published on Cutecom.
The board shuts down when attempting to flash the code and can only be turned on using the S2 button.

Steps Taken:

To address the live data issue, I created an overlay file (as in https://libre.solar/bms-firmware/src/dev/customization.html) in the app folder with the following code:
{
chosen {
thingset,serial = &usb_serial;
};
}

I then built and flashed the code using the "west flash" command. When attempting to monitor the board using the "west espressif monitor" command, I encountered the following output:

Additionally, when I tried to flash the code again, red and green leds turn off but there is voltage at the bat+, bat-, pack+ and pack-. When the leds are off the "west espressif monitor"command gives this:

On exiting the espressif monitor not able to flash code again. On holding down the S2 button the leds turn back on after blinking for a few seconds:

I would appreciate any guidance on resolving these issues. Specifically, I need help with:

1) Diagnosing and resolving the issue with live data not being published on Cutecom.
2) Understanding why the board is shutting down during code flashing and how to prevent this from happening.

Additional Information:

Board Model:  Libre Solar BMS C1 (v0.3)
Firmware Version: v23.1-1-g55c2ea2-dirty.

If an issue is unrelated to the topic of this issue, please open a new one.

Live data publication on the USB serial is now disabled by default. As mentioned in the release notes, the Zephyr shell is now exposed to the USB serial. In order to enable publication messages on the shell, enable it here.

Regarding your problem with flashing: Did you keep the serial monitoring on while you tried to flash (espressif monitor or CuteCom)? That's not possible, as flashing uses the same serial interface.
