One second delay occurs between consecutive frames.

[HyoungSikKWON]

First of all, thank you very much for creating such a useful module.

When using CAN-FD, a delay of 1 second occurs between consecutive frames as shown below. (candump log)

isotp_params setting values

isotp_params = { 'stmin': 1,
'blocksize': 8,
'wftmax': 0,
'tx_data_length': 8,
'tx_data_min_length': 8, 'tx_padding': 0x55,
'rx_flowcontrol_timeout': 2000,
'rx_consecutive_frame_timeout': 2000,
'max_frame_size': 4095,
'can_fd': True,
'bitrate_switch': True,
'rate_limit_enable': False,
'rate_limit_max_bitrate': 1000000,
'rate_limit_window_size': 0.2,
'listen_mode': False,
'override_receiver_stmin': 1, }

You set override_receiver_stmin=1 You are enforcing a delay of 1 second. https://can-isotp.readthedocs.io/en/latest/isotp/implementation.html#override_receiver_stmin

I realize that there is a discrepency between stmin and override_received_stmin. On takes byte value that maps to a time, the second takes a time value given as float.

Sorry for wasting your precious time. I understood it to be the same as the "stmin" parameter, not seconds. thank you. I will read the document carefully from now on.

No worries. I would have assumed the same. Passing a time values gives more freedom and does not constrain someone to use values available in iso15765
