I have an Arduino Mini Pro 3.3 V powered from a coin cell(3.6 V, CR2450) and connected to Bluetooth Mate Gold. I have checked the connections and they are fine. I can also connect to the bluetooth from while trying to upload the file and also from Android bluetooth terminal.I am not sure if it could be bootloader issue as I have checked 2 Arduino Mini Pros that give the same problem running the sample sketch on the bluetooth hookup guide.
- Arduino: 1.6.5 (Mac OS X)
- Board: "Arduino Pro or Pro Mini, ATmega328 (3.3V, 8 MHz)"
The error is:
Sketch uses 2,412 bytes (7%) of program storage space. Maximum is 30,720 bytes. Global variables use 210 bytes (10%) of dynamic memory, leaving 1,838 bytes for local variables. Maximum is 2,048 bytes. avrdude: stk500_recv(): programmer is not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
I burned the bootloader again but no success.
I get the same with UNO. However with UNO, when I press the reboot button before the program uploads is works.
Could someone point me out to the solution to this? Thanks
