Sometimes when I try tic.get_current_position() I get TypeError: object of type 'NoneType' has no len()

[dragospascale]

This happens in ticlib/ticlib.py", line 545, in _block_read because at line 543 result = self._read_response(length) does not return an object
Maybe treat the error and retry to call again _block_read
I'm using micropython on ESP32
Sending commands over UART is working but getting position or variables sometimes return values sometimes not
