Arduino Pro Mini 3.3v WT12-A

Wireless & IoT

Hello All,

I have an Arduino Pro Mini 3.3v attached to a WT12-A bluetooth module, this is almost a similar setup with the Arduino BT (except it uses WT12 instead of WT11)

Serial connection is working at 9600. I have a pre-uploaded ASCII Sketch sample at Serial.begin(9600).

I can see the serial output of the Arduino Pro Mini via Bluetooth. It is working fine. Except for upload of sketch.

I have updated the preference.txt and set the serial.burn_rate=9600;

I would like to know if there is something I missed? Or is the Arduino Pro Mini 3.3v able to accept upload sketch at 115200 only? Or is it a matter of timing (clicking the upload button vs. clicking the reset button of the arduino)

Any advise is highly appreciated :smiley:

is Arduino Pro Mini 3.3v 8Mhz programmed to accept sketches at 19200 only?

Replies are highly appreciated.
