Thanks for the issue
Could you provide more details on mode used to reproduce it ? (as there is multiple mode for the real-time sniffer) ?
- After some checks on HydraFW v0.8 vs v0.9 beta I confirm there is no any change related to HydraNFC
Note: I have just updated the source code of HydraTool to v0.3.2 (to support parity enabled/disabled) could you test it ?
Thanks to provide more details on exact version of HydraFW tested which reproduce an issue
from hydratool.
Thanks for the details
-
Could you do a capture with hydratool -> SaveDirectToDisk and provide the file when the issue appears on FW v0.9 ?
If possible please do the same with FW v0.8 where all shall work fine
Thanks to provide the files for check -
Could you check the sniffer with ASCII mode and capture it (on both FW v0.8 & v0.9 woth same test) to check if it works fine ?
Thanks to provide the files for check
Note:
Thanks to confirm if you use C32HM-DDHSL-0 or an other variant
I hope you have good connection / wire and short wire (less than 15cm if possible) for the connection between C32HM-DDHSL-0 & HydraBus as it is quite sensitive at 8.4Mbit/s
from hydratool.
I confirm this issue is fixed with latest hydrafw master 55e5dbe
See archive build_HydraFW_v0.9-beta-65-g55e5dbe_HydraBus_HydraNFC.zip of the firmware pre-built
See hydrabus/hydrafw#93
from hydratool.
Thank for quick reply.
I have used the mode nfc sniff bin frame-time

I did try with version 0.3.2.0 of HydraTool, unfortunately the issue remains. I will upload fw v0.8 again for testing
from hydratool.
Here it is:
debug_captures.zip
You will find inside:
[debug_captures]
[fw_v0.9]
- fw_v0.9_bin_capture.bin
- fw_v0.9_ascii_capture.txt
[fw_v0.8]
- fw_v0.8_bin_capture.bin
- fw_v0.8_ascii_capture.txt
Hope this will help.
Also I confirm I'm using the FTDI C232HM-DDHSL-0 cable. Wires are connected directly on the board withtout any cable between.
edit: The sequences I have recorded are not the same of course. I was just playing by putting a tag in the field of a ISO14443 reader. So it is mostly polling from the reader.
from hydratool.
Thanks for all details
After checking the fw_v0.9_bin_capture.bin I confirm there is definitely something wrong I suspect the UART speed is wrong ... as the fw_v0.9_ascii_capture.txt seems to work fine
I will do some tests and fix that as soon as possible but it will take few weeks as I'm very busy with tons of things
from hydratool.
There is not any urgency about this, actually I can live with the fw v0.8. Thanks for the investigation. Let me know if I can help for the fix.
Regards
from hydratool.
I have done some fix especially one which should fix this issue (added missing explicit initialisation of bus_mode added in latest refactor => mode_conf.config.uart.bus_mode = BSP_UART_MODE_UART)
hydrabus/hydrafw@5204114
Could you rebuild the firmware with HydraFW master and tell me if that fix the issue
Note: This issue shall be part of HydraFW issue (even if I have fixed minor things at same time in this tool)
I have created it here hydrabus/hydrafw#93
from hydratool.
Sorry for my late reply. Actually I don't have the tools installed for building the HydraFW and to be honest I prefer to avoid installing them.
