Documentation for BlueDuino R2


I just got a BlueDuino R2 and am trying to find documentation.

  1. Where can i find a comprehensive list of AT commands and modes?

  2. Is there a wiring diagram for firmware upgrade available? I have 1.7.2 and do need to upgrade, but got confused by the wiki page.

Thanks in advance,

Here’s the wiki for BlueDuino. Here’s the wiki for upgrading firmware.


Is there a diagram of wiring for firmware update available? The wiki is confusing.


For update firmware, you need a extra USB to UART converter. Only need wire 3 pins.

Left is USB to UART converter, right is BlueDuino.

  • RX -> RXI
  • TX -> TXO
  • GND -> GND
