I am investigating building my own HC05 Arduino programmer since my attempts, following various online howtos, has failed.....other than if I manually reset the Arduino by pressing the rest button.
I am thinking of building my own programmer with an UNO plus HC05.
So what I have done is as follows:
1) Hooked a HC05 up to Serial1 on a mega. 2) Wrote a sketch that simply dumps what ever comes through Serial1 to Serial Monitor. 3) Connect the Mega to my laptop via the USB cable. 4) Made a bluetooth connection from my PC to the HC05 module - COM40 5) Attempted to upload a sketch to COM40.
What I see on serial Monitor on my laptop is 27 1 0 1 14 1 at 10 second intervals until the IDE on my PC times out.
So what do these value represent?
And what is the IDE expecting to receive from the arduino mcu?
