I have a wemos d1 r2 (v2.1q) that won’t accept uploads from arduino.
The port is correct, the baud is 115200, the board type is “Lolin(wemos) r1 d2 & mini”.
I get “timed out waiting for packet header”.
Also tried board=wemos d1r1, with different upload errors.
Then I swapped to a espduino-32 (hw-729), with similar failures.
swapped USB cables, same results.
If you know the secret to making either of these boards work, please share!
