I have both a Raspberry Pi 3a+ and 5 working with a Bittle (not X) with the 2x5 connector. I purchased the Orange Pi 2W 4G for the small size with > that 2GB of RAM. The pinouts look the same and the faq site says they are: "21. When it comes to low-level peripherals, what does compatible Raspberry Pi refer to? A: It means that the 40pin pins are the same as Raspberry Pi." (From: http://www.orangepi.org/orangepiwiki/index.php/FAQ) But when I boot with them connected, the robot does odd things and the Orange PI cannot be logged into. I updated the firmware and I'm using the latest version of Debian Buster Server from Orange Pi.

I have read through the voice information here: https://docs.petoi.com/extensible-modules/voice-command-module (https://docs.petoi.com/extensible-modules/voice-command-module) I would like the bittle to respond to a custom command with the behavior "backflip" and the audio response "good stuff" However, I'm having a tough time discerning if it possible as the return value to serial seems to only contain a behavior command? Is there a way to make such a mapping in voice.h ?

I have the Raspberry PI 3A+ working with Python 3 when I use USB to USB. I can use ardSerial.py to send commands. So I know I have the software setup correctly on the Raspberry PI and that the Nyboard responds. I have soldered the 2 x 5 socket on and when I connect this way, the commands do not work. It seems to upload them, but never comes back from the operation. minicom connection is similar - no errors - but no response upon connecting. The Raspberry PI fires up and I can access it when connected this way - so at least the power is working. Suspecting a possible bad solder job, I have remelted the solder joints to reset them - did not help. I have 1 wire disabled, serial port enabled per the instructions (but I think if I had this wrong it would show up in the USB to USB test?) I bent the 6 pin programming connector 180 degrees to connect both the computer and the Raspberry PI to troubleshoot. When I send commands from the Pi, the serial monitor on the usb port is not seeing anything and it just hangs forever. Things I'm wondering about: Question 1: I have reloaded Bittle's WriteInstinct in the past - is it possible that there is a missing library (even if it works via USB - seems unlikely). Question 2: Is there any way to diagnose a bad pin from either side? Question 3: Putting a new 2 x 5 on the board would be challenging for my desoldering skills - would anyone here suspect the connector block itself? Question 4: I am using the /dev/ttyAMA0 port - but that port is present even when the Pi is not connected to the Nyboard. Does that sound right or indicate a hardware problem? FYI I have all my code in a Git repo that I will make public. With a single curl command you will be able to download and configure all that I've done. Once it's working I will share!
