UART sleep

[mat214]

I use the script with node red to manage my battery.

After a while the command:
daly-bms-cli -d /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0 --all

returns the same data inconsistently. For the correct data to come back I have to unplug and plug the USB-UART back in.

Here is the return of the command when it does not work correctly:

daly-bms-cli -d /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0 --all { "soc": { "total_voltage": 0.0, "current": -3000.0, "soc_percent": 0.0 }, "cell_voltage_range": { "highest_voltage": 0.0, "highest_cell": 0, "lowest_voltage": 0.0, "lowest_cell": 0 }, "temperature_range": { "highest_temperature": -40, "highest_sensor": 0, "lowest_temperature": -40, "lowest_sensor": 0 }, "mosfet_status": { "mode": "stationary", "charging_mosfet": false, "discharging_mosfet": false, "capacity_ah": 0.0 }, "status": { "cells": 0, "temperature_sensors": 0, "charger_running": false, "load_running": false, "states": { "DI1": false }, "cycles": 0 }, "cell_voltages": null, "temperatures": null, "balancing_status": { "error": "not implemented" }, "errors": [] }

only the raspberry pi is connected to my battery. Daly returns me a consumption of 0 A while in charge I could clearly see 20A. I have in parallel a shunt and an ina226 which gives me a consumption of around 0.3 A.
