Hi,In ST25RFAL library, version 2.8.0, in rfal_isoDep.c, function rfalIsoDepHandleControlMsg(), when ISODEP_S_WTX messages is handled, the code limits how many times a card can request wait time extension, specifically, this line: if( (gIsoDep.cntSW...

Hello,I am using ST25R3911B and trying to understand in what cases Soft Framing Error will be generated - this is bit I_err2 in register 0x19.Based on the datasheet, it looks like this is only used when operating in NFCIP-1 mode, which is enabled by ...

Hello,I am trying to use STM32L476 to interact with a Smartcard.I am using USART1 in "SmartCard with Card Clock" mode.I have the "NACK If Parity Error" enabled.I am having a problem where the USART receiver detects parity error on the line, but does ...

Hello,I am looking at the smartcard example application - https://github.com/STMicroelectronics/STM32CubeG4/tree/master/Projects/STM32G474E-EVAL/Examples/SMARTCARD/SMARTCARD_T0_MFXIn the project .ioc file, I see that the Baud Rate is set to 10752 Bit...

The ST25R3911B datasheet indicates it supports VHBR. In the RFAL code, there is default configuration for NFC-B VHBR rates, but nothing for NFC-A (ISO 14443-A).Are VHBR rates supported for ISO 14443-A?

Hello,Thank you for this sample.But I do not think it will work with USBX. Specifically, if you look at ux_device_stack_descriptor_send(), the part that handles UX_STRING_DESCRIPTOR_ITEM, it assumes that the string framework string value is a ASCII s...

Hi,Regarding when the soft framing error could be raised - all clear. Thank you for explaining.But I am still not clear regarding the ST RFAL source code - as mentioned in my previous post, the code in one place uses EMD and in another, for the same ...

Hello,Thank you for this clarification. It is good to know that the soft framing error can be triggered for other protocols, not just NFCIP-1.To have common base for the discussion - I use the source code from ST25RFAL001_v2.4.0.If you look in rfal_i...

Hi,I do not have information about the tag that was used.My setup is ISO-14443 Type B, ST25R3911B-DISCO, using the ST RFAL library.I am trying to understand if the Soft Framing error will be raised in all cases or only when using NFCIP-1 mode. In the...

I think I figured it out. It looks like, for both questions, the setting "Number of retries in receive and transmit mode" is what controls the behavior.If number of retries is 0 (as I have it), then no NACK.Changing the setting to 1 or higher, result...
