Unable to upload sketch #135

Just got a T-Watch 2020 and I keep getting a time out waiting for packet header error. I've had this before on some other dev boards that just need to have the boot button held while connecting, but the one button on the t watch doesn't seem to do this. Work around? Solutions?

Try pressing the reset button about a second after the last dot has appeared in the "dots and lines" pattern. It needs good timing, but works every time for me.
