Multi-m3pi Communication with Wixel

You should be able to change the Wireless Serial App so that when the computer sets the baud rate on the virtual COM port to something between 0 and 255 the Wixel changes the radio’s channel number to equal that “baud rate”.

In a previous post a year ago, you wrote:

To change the channel, I think you would need to send the SIDLE strobe to the radio (RFST = SIDLE), wait for a few microseconds or poll MARCSTATE to be sure the radio reaches the idle state (see Table 71 of the datasheet), change the CHANNR register, and then start the radio again by sending the appropriate strobe (RFST = SRX in your case).

After reading through some of the Wixel SDK source code, I understand these instructions, but I am unsure about what to look for; how can the Wixel tell if the computer has changed the baud rate? I was also wondering, would this sort of dynamic channel-changing be possible for Wixels running attached to an m3pi (ie, would an m3pi be able to instruct its attached Wixel to change the channel as well)?
