Access to BT0 #16
Description
Ran into a problem whereby STLink, Black Magic Probe and Ser+/folie could not take control while running the STM32duino bootloader and this sketch. Suspect code problems when running on STM32.
I needed to use BT0 to 3v3 to get back in control of the node. Used a jumper wire to the BT0 hole assigned to Red-Pill.
