hello to all
I have a problem
How to upload a firmware into BW16
Which pin need to use as DTR or yet?
i try mosi,
try to close pb1_txd && pb2_rxd

result is null
Arduino IDE take me
"Enter Auto Upload Mode
Uploading…error: Device not supports Auto Upload Mode

Upload Image done."

or

Hi @lauway6v,

May I know what is the actual problem you are facing? Unable to flash firmware into BW16?

Thank you.

ok
solution
first step
ground + TX
3.3 + EN
second step
ground + TX
EN + ground
third step
free TX
EN + 3.3 aka VCC

and press “upload”

then wait after 5 seconds will go uploading

Warning need
to check EN ±+
because i think its GATE of MOSFET

Youtube help you and me.
GodBless Youtube, amin ^)

tx = -
en = +
en = -
tx = 0 ( free - not connected to another )
en = +

or
tx = -
en =+
en = -
en = +
tx = 0 ( free - not connected to another)

after upload need disconnect en from +(vcc)

p.s.
not forget right sequence
one from two examples - is working 100%
