Hello @desmbr indeed, that doesn't look good. I wonder if maybe the internal battery is defective preventing the power rails from reaching the proper voltages. Edit: first, however I would unplug the hat and maybe try a different USB power supply. If you still have warranty, I suggest you ask for a replacement. If not, you might try to open it and disconnect the battery to see if that helps. These pictures I took a while ago might be helpful opening M5CoreInk. Thanks Felix

Use a compatible RFID reader, authenticate if necessary, and send read commands via software or microcontroller in order to read a block from an RFID tag. Make sure that proper protocols are followed (LF, HF, UHF) and that data is retrieved securely. Integration of identification and access control systems enhances their efficiency.

@figgalicous The desktop IDE hasn't been updated in a while. The Web version gets updated weekly.

@felmue thanks I will check it out and make better use of the project zone as a how to learning aid.

@zaraken CoreS3's audio.Player can support these functions.

@novablue6879 Hi, I finally understood that the update will be released in the UIFlow2 interface at the end of the Chinese New Year. The update will include the program to make the Bala2 move.

I had a similar issue. What solved it for me, was to add the Init SDCard block and increase the frequency. So I'm guessing that reading from the sd card was just to slow to be able to play the music smoothly

Hello @hmwavem works for me. See example in UIFlow2 Project Zone: M5Dial_WiFi_AP_UIFlow2.2.1 Thanks Felix

@aivarannamaa This solved the problem. Thanks!

@felmue Thanks for your help. I'm waiting to hear from tech support.

@louisandthecat Do you mean updating the microPython code over Wi-Fi?

@m5hehehe the i2c driver install error do not affect any function, please review your codes

Hi @riztronic We have fully tested the Arduino code running normally and without a problem! You can get the newest code here: https://github.com/m5stack/M5-LoRa-E220/blob/main/examples/P2P_TX_RX/P2P_TX_RX.ino The test video is here: https://www.dropbox.com/scl/fi/soim9m8aonp52850p5xqs/361e2e27700890d74db6e65082fd4d05.mov?rlkey=tay4leplto1qlrsl2zt9s549d&st=dff6d295&dl=0 The problem may be that your TX/RX pins are reversed
