Hi ST Team,I just integrated ULD driver of VL53L1X but it keeps returning range status: 4. What could be the problem?Settings:Timing: 100Inter Measurement: 100Distance Mode: ShortROI: 16x16Signal: Default ( 1026 something )Sigma: 90The I2C communicat...

Hi,My setup is ST25R3911B / RF-HL ported to ESP32.Recently came across NDEF middleware in "ST25NFC_Embedded_Lib_ST25R3911B". I'm trying to read T2T NFC-A cards but whenever I try to run the NDEF middleware part, the "ndefPollerNdefDetect" function re...

Hi,I've implemented the RFAL-HL ( Higher Layer ) based on X-Cube-NFC5 in our project.Currently, the example only provides us with a way to detect tags only. I would like to know, what's the procedure by which we can send an NDEF data packet to a P2P ...

Hi,I have ported RFAL library to ESP32 platform and have set up proper interrupts for it to function in capacitive wakeup mode.So the issue:We are using RFAL-HL ( higher layer ) in our project ( based on X-Cube-NFC5, but using the latest version of R...

Hi John,The sensor does seem to be stable after the driver is implemented without any flaws. Thanks for the help!Just a small question: The results are within + or - 15mm, Is this normal for short distance mode?Regards,Ayush

@John E KVAM My bad! I took a look at my platform file again, the RdByte function was correct that's why I was getting all the reference registers correctly but I was overwriting the I2C buffer in some functions ( RdWord & WrWord ). Resolving that i...

@John E KVAM Thanks for the quick reply!I've tried different lengths ( 750mm ~ 250mm ) and target reflectances ( Marble, Black Tile, Hand, and Cloth ), In all of the cases it returns a range status 4 which is pretty weird, I've worked with VL53L0X ...

You were correct. The ISR was not getting called immediately after re-attaching. So I added a couple of lines after re-attaching to detect the IRQ status and fire that interrupt anyhow.Card detection and collision have been fixed. But timing is still...
