Hi,

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,  
Mike

Here’s [the wiki for BlueDuino](http://wiki.aprbrother.com/wiki/BlueDuino_rev2). Here’s [the wiki for upgrading firmware](http://wiki.aprbrother.com/wiki/BlueDuino_R2_How_to_upgrade_firmware_for_CC254X_module).

Thanks.

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.
