Web API to control Nybble - OpenCatWeb

I will definitely port my code to Bittle once my Kit arrives and @Rongzhong Li doesn't forget the wireless dongles. ;)

If you already have a Bluetooth connection you could try to directly communicate with Nybble like here:

I will also focus on extended web support on the new BiBoard platform, but this will take some time as I don't know how advanced the prototype is yet.

@leukipp ok ci tengo e ti seguo in questo post. grazie

Is that going to be NyBoard v0_3? What will the all in one board include? Personally, I'd love to see, WiFi, Bluetooth, GPS and wireless charging included. But that's just my wishlist.. hehe!

@FuzzyFoyz It will be a board with WiFi and Bluetooth. GPS is not included. We will also have a battery pack with onboard charging and protection circuit.

@FuzzyFoyz New board with serial2 you can add a small GPS module such as NEO-6M/8M. Not included in the official pack.

"The Pi is set as the master device on the Nybble PCB" might be the problem.

The master switch "Ar/Pi" determines the master of the I2C network of the NyBoard. If you dial to Pi, Pi will take over the I2C devices such as the PCA9685 servo driver and MPU6050. In that case, even if you are communicating with the NyBoard through serial port, the NyBoard won't be able to control the servos.

@Rongzhong Li @leukipp Thanks Rongzhong for your answer. This is the current situation for my cat:

• I set the master switch to Ar

• I reinstalled raspian, configured everything and redownloaded the git file to the raspberry

• ssh into the raspberry is successful

• I can sent from ard.Serial.py the kcr command and Nybble reacts! (yes!!)

• When I start the Flask server developed by @leukipp I cann acess the web page but if I click on one of the three buttons in the upper left corner, nothing happens... Any ideas?

@John Doe Make sure the serial port and baud rate in ardSerial.py match those defined in the bus.py file.

If you’re able to send commands to the Nybble with ardSerial, the web api should work too. I’m using dev/serial0 and a baud rate of 57600 as I’ve Nyboard 0_2.

Also: I‘ve learned Pi’s have different serial settings — the 3A works out of the box with Nybble, but the 3B needs some configuration.
