Hey I need some help, I have a 2.3.2 Voi, dashboard ES4 with BLE555, ESC flashed with STlink and now with CFW but the battery BMS I can't flash it.
Stm32 doesn't read and TX RX port are blocked. The chip has a 2 pins with tx and Rx but u know is SMD technology.
Before flash ESC I try to flash BMS with Iot port but didn't work.
ESC tells me an error 27 before CFW and now tells error 45 and 22, battery errors
Battery is 100% charge I don't know guys If somebody explain me how to flash BMS at this point save my life
