Question

HV B1.4 + ATC_ota_40000.bin = brick

Regressor opened this issue 7 months ago · comments

I flashed two devices with ATC_ota_40000.bin and got two bricks. No screen, no BT.

I soldered CH340 usb to ttl adapter (3,3V) but allways getting "Use reset chip (RTS-RST): see option --tact". I tried to change speed down to 340000 and only -b 480000 sometimes shows 1 or 3 sectors flashing. Changing timeouts up to 0.5 didn't help...

Connection: rts to vcc, rx to P14, tx to 1K then to P14, gnd to gnd.

This is the best result:

Flashed with https://pvvx.github.io/ATC_MiThermometer/USBCOMFlashTx.html
python version unusable :(

Thanks for the report. New transitional firmware from yesterday was not thoroughly tested. And now it is tested and good to go. Sorry for inconvenience.

Got one more sensor. Flashed it over ait. Fix confirmed.
