Just received M5StickC Beetle C. I was able to run the Arduino example and use the wifi page to control it. Here are few observations: 1) Wheels are attached very loosely and easily fall off. Are they supposed to be glued on? 2) Seems like there should be a guide or some feature to keep the M5StickC on the Beetle C better. Seems to be able to wiggle loose, especially if you are pressing buttons. 3) Having to slide the switch to the left to turn on the BeetleC seems non-standard. Maybe it would be nice if a small LED was lit when the unit it turned on. 4) There are no instructions on how to charge the battery. I have to assume that if I have the M5StickC plugged into it and the USB cable plugged in, the Beetle's battery is charging as well as the M5StickC battery. When the M5StickC battery charge is full does the battery charge on the Beetle stop? Do I have to have the Beetle turned on? 3) Documentation for how to use the device is missing, outside of running the Arduino example. One can glean a lot of control syntax from the Arduino example but are there any other features to make use of? One nice one would be to be able to see what the Beetle's battery voltage is. At any rate, it'd be nice if there was good documentation. That issue is common to alot of the M5Stack products. 5) The control app is nice but having to control both wheels separately seems awkward. Probably be better if there was just a simple speed, straight,backward,left,right,spin left, spin right interface. None of these issues are enough to say the product is no good but they detract from how good the product could be. Probably the most irritating issue is that two of the wheels fall off very easily. I think I need to get the super glue out. The second most irritating issue to me is in regard to the unknown care and feeding of the Beetle's battery.
