I've just released the Chibi stack v0.91 and chibiArduino stack v0.51. For Chibi, I added the sleep mode function to the AT86RF212 boards. I also removed unneeded code that added a carriage return to the virtual COM port whenever it saw a newline. I found that this caused some strange errors and was actually not needed so I decided to strip it. The additional carriage return is automatically added in the chibi command line handler already. For both stacks, I fixed a bug where the radio required a delay when waking from sleep mode to allow the PLL to lock.
But probably the main feature I introduced in this release is the support for promiscuous mode. Being able to support promiscuous mode opens the door to an extremely powerful feature where you can turn the stack and hardware into an 802.15.4 packet sniffer. When used in conjunction with a protocol analyzer like Wireshark, it becomes an extremely powerful tool for protocol stack and software development, debugging, and security research. I'll be talking more about this in the next post.
The chibiArduino Datasheet was also updated to include a Troubleshooting section and a matrix table for setting the power jumpers and switches on the Freakduino.
Also, the chibiArduino HOWTO guide was updated with the CHIBI_PROMISCUOUS parameter definition.
