Unable to upload via bluetooth with HC-05

Development Tools IDE 1.x

Hi,

I try to use my HC-05 bluetooth module to upload my program.
For now it is an empty program.

void setup() {
  Serial.begin(38400);
}
void loop() {
}

Here is the wiring a made:

But nothing happens. It keep saying "Uploading..."

I choose the right board and the right port (/dev/cu.HC-05-DevB), I'm on OSX.
When I open the Serial monitor there is a communication happening and maybe this is what is blocking the upload?

The problem is that I already made this work one day without any trouble but now I can't understand why I'm not succeeded.

Thanks for your help

Thanks, I did not wanted to do all these steps at first but...
Even after doing everything I was getting the same error, it finally worked when I've set Serial.begin(57600); in my setup.

Wow. That's a lot of work done on the HC-05.

I think I'll be lazy and stick with buying a FTDI USB to serial adapter on eBay from a trusted source recommended here on these forums.

Yes, it does take 20 minutes or so to build a wireless adapter. It is pretty fun to have a Pro Mini that programs via Bluetooth and don't have to plug/unplug from USB.

With my poor soldering skills, I'd be "toast". :slight_smile:

I have used jumper and no resistor, it's still working though.
