ValueError: buffer to small when using uhf-rfid with core2

[kapipema]

Hi,
I am using a Core2 together with a uhf-rfid unit and it works mostly ok but sometimes I get a "buffer to small" error.

Traceback (most recent call last):
  File "m5ui/port.py", line 46, in task_handler
  File "<stdin>", line 33, in button0_event_handler
  File "<stdin>", line 28, in button0_short_clicked_event
  File "<stdin>", line 18, in inventory1
  File "unit/uhf_rfid.py", line 19, in inventory
  File "driver/jrd4035/__init__.py", line 72, in inventory
  File "driver/jrd4035/__init__.py", line 445, in command
  File "driver/jrd4035/__init__.py", line 490, in _receive
ValueError: buffer too small

I can't seem to find what is triggering the situation.
It is not related to a specific tag or any other situation that I can figure out but it never
happens where there are NO tags around.
Even if I trigger the inventory manually it happens from time to time.

Is there any way of figuring out and/or change the buffer size or fix the possible bug?
