Auto Reset With Botboarduino

[kinect_guy]

I am familiar with the auto-reset function of the Arduino. You tie a ~100 nF capacitor from RTS of the serial port to the reset pin of the Arduino (along with the RX, TX, GND, Vcc of course). Voila!

This does not work for the Botboarduino. I even switched out the ATMega with the Duemilanove for one with the Uno bootloader to no avail.

I am currently trying to do this with a bluetooth module for remote upload capabilities. Right in front of me I have an Uno and a Botboarduino. Using the circuit I mentioned above I try it with the Uno, it works. Put the Uno chip into the Botboarduino, it doesn’t work. I am using the correct baud for the bluetooth module, and am making sure to choose the Uno board in the “Tools” menu.

From my understanding, the only difference between the two is the USB chip, which should not affect this circuit at all.

I should also mention that I can get the bluetooth upload to work on the Botboarduino if I reset it manually.

Any insight on the topic is appriciated!

Hi,

To be specific, you can use either DTR or RTS, which should both be triggered by the Arduino IDE before programming.

Could you please reply with one or more pictures clearly showing your circuit with the BotBoarduino to cause the auto-reset?

Please note the BotBoarduino already has the capacitor and pull-up resistor attached to the reset pin for auto-reset capability (from pin DTR). You can view the schematic in the documentation here. This may interfere with your circuit.

Sincerely,
