I have the same issue. I can’t send any code to the Hercules board.
- In the Arduino editor, I’ve set the port to the UARTSbee, Board to Duemilanove, Processor to ATMega328P
- I have then connected the UARTSBee to the Hercules board. The board is not powered by the battery back.
- When I connect the UARTSBee to the computer (Mac or PC, tried both) it lights up, and the Hercules power also lights up.
- Any time I try to update a sketch I get
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0x00
And I get exactly the same if the UARTSBee is disconnected from the Hercules.
Q. What am I missing?
Q. Should the UARTSBee be set to 3v or 5v?
Q. Why can’t the UARTSBee communicate with the Hercules?
Any help gratefully received!
