@wjcarpenter Standby voltage. the stick doesn't truly power off and there is always a small voltage present in the stick which is why the battery always runs out.
The voltage increasing with a cable plugged in is normal and thank you for pointing out this function.

@kenneth123 Just tried and logged in with no issues.

Hello @smily77

according to the schematic GPIO15 is used as reset pin (SOC_EXTRF_RST).

Thanks

@Slarck You should always Erase first because of this. never just burn only.
Thats the reason for the big red erase button being there!

@yuyun2000 Did you Erase existing firmware first?

@jbruggem Your first post shows that

1. you haven't configured Arduino to configure code for the M5Stack Core2 which uses a different core and pin config to a base esp32.
2. The example you are using is not an M5Stack demo,
3. Arduino is missing Libraries.

All these errors point back to not have the M5Stack Core2 board type selected.

@Slarck My pleasure.
Alas Last years attempt failed as everyone was too busy and this year I'm in the process of replacing my workshop along with with other sheds But I will announce the 2025 version again in September. on all social media channels this year.

Hi guys

corresponding github issue for reference.

It seems there isn't an easier way just (yet) than using Espressif Library Builder.

Thanks
Felix

@jeremyn3 You need to follow the instructions on the CoreMP135 product page.

Hello @peolsolutions

please stop posting mostly irrelevant information. This topic is about how to remove the magnets - not about what the magnets are good for.

Thanks
