error in scan with pyhon 3.7.2 #93

Open RiccardoBa opened 4 years ago

RiccardoBa commented 4 years ago

When I try to connect an RTU device during the scan I get an error because the instruction does not work. data[:4] is a string and then also if the base_addr is right systems not recognize it. `if data[:4] == b'SunS': self.base_addr = addr

print('device base address = %d' % self.base_addr)

break`

I've tried to change b'Suns' in 'Suns' but I get an error in a following statement. This is my python code import sunspec.core.client as client d = client.SunSpecClientDevice(client.RTU, 1, 'com9', baudrate=19200, timeout=10)

address, Com, baudrate and timeout and connection using sunspec dashboard works correctly.

This strikes me as a duplicate of #60. Maybe give #62 a try (yourenv/bin/pip install git+https://github.com/altendky/pysunspec@60-altendky-bytes_for_both_py2_and_py3).

Updated with a fix. Give it a try and see if it works for you.
