My Bittle gives a continuous alarm when connected via USB, reset does not work. Remote does not work. Just before that I could do a reset and recalibrate. At then end only the c command worked,
What does this mean?
I removed the battery and then I uploaded WriteInstinct again. Recalibrated everything and now it is silent again. It stil does not respond to the remote or any command except c.
You need to turn on the battery by long-pressing its button for 2~3 seconds.
The WriteInstinct.ino only writes constants to the board so it doesn't have the low voltage alarm. You need to upload OpenCat.ino afterward. I suggest you download the newest OpenCat repository on GitHub as we keep upgrading the code.
Please refer to chapter 4 of the user manual at docs.petoi.com. It's a complex system to be understood carefully.
