I agree quite frustrating, when you follow the sample and get no results.

Any pointers in the right direction would be fantastic.

Hello,

I have both the RFID RC522 unit and UHF-RFID unit. I can easily configure the RC522 to read tags and cards and return the relevant tag id etc. However when I try with the UHF-RFID no information is returned.

I'm not sure If need specific types of tags for the UHF-RFID.

Any Pointers would be fantastic.

regards

Kyle

Hi

I'm wondering if there are any versions of the UnitV camera without a case?

Hello,

I have face and QRCode detection working on the K210 UnitV. I want to capture the button press on the sides of the Unit. Is there some sample code for this.

Thanks

Kyle

Hi,

I have been able to read and write to Mifare tags however I cannot find the block location for the NDEF information on a NTAG215. the UID is readable but I cannot get any other info on the tag.

I access Mifare with this
rfid0.readBlockStr(1, keyB=[0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF])
and its working

Trying to find the right NDEF block location
rfid0.readBlockStr(4, keyB=[0x03, 0x04, 0x05, 0x06, 0x07, 0x08])

Any pointers would be awesome.

thanks

Hey,

I'm looking for a neat way to attach a top sensor to a grey core. So it can sit next to the screen. Any ideas would be welcome.

Thanks
Kyle

@m5stack

With M5Cam is there a menu config example to make this work correctly. I have tried many configurations and it reboots on load .

Any suggestions would be great, I have had it working with the firmware you supply but cannot get the menu config working.

Thanks

I have found the same with USB connected devices they are very difficult to connect with.

Awesome thanks all working

Hello,

Today I opened a new M5StickC with the factory firmware on which was working. I then when to burn the latest version of UIFlow firmware 1.6.1, however it keeps rebooting.

with the following on console. I'm sure it's not a great thing but hope it can be recovered. I can and have returned the factory demo firmware and this works.

thanks for any help.
