I have a Petoi Bittle with Nyboard v1.2 that I was trying to upgrade the firmware with from my Mac. It says parameters uploaded and then the Mac app crashes. Since then I can connect to it with the mobile app, but when I send a command such as Stand it beeps repeatedly and doesn't respond. The yellow and blue lights on the board are on.
I dont have the USB module so limited to Bluetooth connection only.
Please help!
I suggest you to open the serial monitor in the Arduino IDE:
In Tools menu, select the correct Port first (the Bluetooth module port likes: /dev/cu.Petoi-****)
then input "n" to skip all the prompt questions. the close the serial monitor to upload the main sketch.
