Hi guys @democrazia : thank you, adding from easyIO import * solved the issue. Thank you! @ajb2k3 : you are correct, the 485 stock version doesn't have batteries. However I don't think M5Stack engineers are planning to separate the two versions in UIFlow as there is only one M5Station to select from in UIFlow. So yes, it is a bug - instead of the error we should get 0. Thanks Felix

I second that request.

Hello @loboris thank you for your suggestion. Unfortunately an on the screen indicator would not be updated properly if the M5Paper is turned off by pressing the reset / power off button. That is where an LED indicator, which is independent of the screen, would come in handy. Thanks Felix

Hello @Zontex Understood. Thank you for checking. Maybe it could still be wired to a GPIO, but via a solder bridge, so it could be used optionally? Anyways, I've soldered a wire from AXP IRQ to ESP32 GPIO35. I can detect now when USB (aka ACIN) has been connected or disconnected while ESP32 is in light sleep and use that to wake up. Cheers Felix

Hi guys Power consumption update: even though the example keeps the M5CoreInk in shutdown mode (everything off except for the RTC) most of the time and only powers up for about 2 seconds every minute to do the update, the built in battery only last for about one week. Thanks Felix

Hi @Zontex No offence, but I went ahead and created my own M5GO in white with some additional modifications, actually mostly removing stuff which consumes too much power for my battery operated project. I've called it M5PogoBottom. Cheers Felix

Hello @sodoku that is actually not a bad idea. I'll keep that in mind. Thank you for suggesting it. Cheers Felix

@felmue Thanks for the sample code ! For rumble part yes it was shaken it.. i have read your kb about Core2 and see not possible without hardware modification... Thanks again for you quick answer !

Hello @Zontex thank you for checking with your engineers regarding possible long term damage for the RTC backup battery. It's good to know there is none expected. This M5StickC Plus was part of order M5-8036 and the serial number is (I think): In case that is not the serial number, then please kindly let me know where I can find it. Thanks Felix

Hi @Zontex thank you for looking into it, I appreciate it. Please let me know if there is anything I can help with or test. Thanks Felix

Hello @buzali no, at the time I used the Arduino environment for my tests. RTC wakeup should be covered by this example. In UIFlow have a look at the Restart on block. You can find it under Hardwares - Power with M5CoreInk selected as device. Thanks Felix

Hello Rop nice, now we already have two keyboard layouts (anybody working on Dvorak?). I like your solution for uppercase letters and the caret handling is nifty - well done. Cheers Fexli

Hi @Rop or a pin drop... thank you for that piece of information - it's good to know the last touch can be retrieved if necessary. Currently in my project I put almost everything to sleep, except for touch (monitor mode) and IMU (setup for WOM). The ULP is monitoring the interrupt lines from both and wakes the main CPU if required. Cheers Felix

Hi @Rop I think I've played with that register setting myself at one point in the past and I also did not see any difference in regard of the area under the circles. It will be interesting to see if that will be improved in one of the next M5Core2 hardware revisions. Thanks Felix
