Is it possible to receive a GPO pulse when an NDEF message is being read by an NFC reader, such as a smartphone? I thought it was possible by configuring the GPO field to RF busy (0x6X) and connecting the GPO port to a GPIO port of my MCU. However, t...
If I perform like a stupid User (write Tag and before the message is published i remove it from the Tag), I am able to get an error message from the NFC-Tag. It's something like "Tag I/O-Error" or "Tag I/O-Error, Tag is not ndef". So if this happens ...
Hello, i have a strange problem with x-nucelo-nfc01a1 shield.I get an i2c timeout but under different conditions it occurs in different places in code.My setup is nucelo board with stm32L073RZ and X-NUCLEO-NFC01A1 shield, and to communicate with M24S...
I have a few thousand units using these tags in the field and have found that under some condition that I'm yet to replicate in the office the tags seem to be able to get into a state where they are unable to be interacted with by either an app (I've...
I'm trying to use X-NUCLEO-NFC01A1 with STM32 F429ZI to read data from phone NFC. When I'm trying to open session HAL_I2C_Master_Transmit(&hi2c1, M24SR_ADDR, (uint8_t*)pBuffer,NbByte, 1)in function M24SR_SendI2Ccommand (file drv_I2C_M24SR.c) returns ...
I have code running on a few thousand units in the field and on the whole they work perfectly, however I'm seeing this problem in a few of the packs and wondered if anyone had seen it themselves or know what causes it or even better what i need to do...
I just need to verify the board design, (that the uP can reach the M24SR on i2c). The documentation seems to assume knowledge of the ISO protocols and I can't find complete packet examples.
Hi, the requirement of my project is to interface x-nucleo-nfc01a1 with blueNRG2 dev board, but i can't get it done.I tried and failed miserable and now I am short on time.can you please provide me the same project for blueNRG2 ?Any help will be appr...
Hello, I`m using M24SR64 to config wifi using I2C on Raspberry Pi.And now I have a problem that after conmunicating with M24SR64 by I2C, and deselect I2C session, I found the RF session is closed too. I want to use Android App to config NDEF message ...
