ST25 NFC/RFID tags and readers

Resolved! What is the I2C slave address of the ST25DV04K? What is the E2 = 0 or E2 = 1 meant to?

Hi,​I'm using a ANT7-T-ST25DV04K, which is basically ST25DV04K with an antenna.​In my project I have a sensor that will take a reading and write to the tag memory to then later retrieve it through RF.I want to access it through I2C, in the datasheet ...

Resolved! ST25R3911B - Low Datarate @ NFC_V_ISO15693

Hi there,we are using ST25R3911B in combination with STM32F303CCTX. Also we are using the "NFC_V_ISO15693" and also the sourcecode from ST to handle the complete communication between ST25R3911B, STM32F303CCTX and also the RFID Tag.But there seems t...

Resolved! When is the python wrapper for the UHF Library expected to be released?

I am about to begin working on a project with ST25RU3993 IC as my reader. The UHL Libraries datasheet mentions that there is Python wrapper under works and would be released in Dec. Can anyone let me know, if it is it still on track and give any exp...

Resolved! Using the ST25R3911B Disco GUI, we are seeing the message "ext field detected, not polling" in the status window. What does this mean?

We are trying to increase the read distance by adding an RF amplifier, routing the "Rx" chain through an external divider to RFI1&2. We cannot find any reference to this message in any of the docs or source code we have. Has anybody experienced this?

Resolved! want to about android sdk functions for PWM control
