Hello PIO 
I added a serial port bluetooth module (HC-05) to an Arduino Uno.
When used in conjunction with PIO’s serial monitor, the device works great. I thought it would be cool to use it for uploading sketches as well so I configured it to do so (I wired the HC-05’s state pin (pin 32) to the Arduino’s reset pin. I’m able to upload sketches flawlessly using the Arduino Ide, but I get a consistent error in PIO when I issue the command:
platformio run --upload-port COM5 --verbose --target upload
(COM5 is the correct port, the HC-05’s baud rate is set to the default 115200).
I’m able to upload using the Arduino Ide, but I’d much rather use PIO. Does anyone have any suggestions? The reported error follows. Thanks.
