Do not try to remove the battery from the RoverC, it is welded in place. According to the documentation the 16340 battery should charge from the stickC usb when the stick C is attached to the roverC or joyC

For which module exactly?

Hi @StuartT there is some bug where the code did not upload completely to your device and caused a glitch. As @m5stack said you need to erase and reflash it, you can do so with the M5burner software, or clicking firmware burner on the top bar of Uiflow desktop version. After that you can erase and choose the firmware which you want to upload. If you are on Linux maybe better to use esptool to erase

There's some example code on the github here:

I created a guide on hackster.io using micropython check it out here https://www.hackster.io/lukasmaximus89/rtc-modules-with-m5stack-46636b you should be able to sync it with ntp by using the datetime function of ds1307 and ntp with settime() this forum post explains it https://forum.micropython.org/viewtopic.php?t=2440

Hi @Happy-Hippo It is true that the bmp280 and dht12 do tend to have their readings thrown off a little by the M5StickC's internal temperature, which was a bit of an oversight on M5Stack's part. Perhaps adding a layer of insulating material between the stick and the yun might solve it.

I cant see how the atmospheric pressure should be so adversely affected though. I'd imagine going with an mqtt platform such as thingspeak or iftt would be the best way to get the weather data to your stick C but I haven't personally tried it. Great idea to pacify your wife, let's see if it works :p
