Yes, I am using HC-05 for uploading to the 328p or 1284p.You must set HC-05 such it toggles a pin thus it works like DTR on FT232.Except setting the proper baudrate you have to setAT+POLAR=1,0 and wire a 100nF (or 1uf) ceramic capacitor between pin32 of the HC-05 and the 328p reset.See morehttp://blog.iteadstudio.com/upload-program-to-arduino-with-bt-shield/
Also, fiddling around with pin 32 on the HC-05, I have noticed that the arduino will reset through a 100nF cap the first time you touch one of tis leads to pin 32 on the HC-05. But then it stops working, and the only way to make it work again is to discharge the cap.So what is that about?There does not seem to be much point in implementing a setup where you can upload a program to the arduino only once via the bluetooth and then have to manually discharge the cap to get it to work again.......assuming of course I could get the damn thing to upload a program to the arduino in the first place.
Hi. I have a computer with Ubuntu and Windows 7 dual-boot. It has built-in bluetooth and I also have a HC-06. I cannot get Windows to connect to the Bluetooth module as a COM port. Is that easier to do in Ubuntu 14.04?
Here is my setup for programming Arduino Megas with a HC-05:
