+[[2. pymodbus On the BeagleBone]]
+
+I spent some time trying to figure out virtual environments on the beaglebone and get the pymodbus scripts running. I was half successful. The virtual environments are now working as expected. I needed to use the requirements.txt method instead of pushing the whole virtual environment. Somehow that leaked the global packages into it. 🤷
+
+For some reason the beaglebone is having trouble actually connecting. I'm running the server on the bone, while running the client on the PC. The client is just saying
+```bash
+danesabo@danesabo-laptop:~/Projects/beaglebone$ python3 simple_client.py 
+Setting up...
+Connecting to server...
+Connection to (192.168.6.2, 5020) failed: [Errno 111] Connection refused
+Traceback (most recent call last):
+  File "/home/danesabo/Projects/beaglebone/simple_client.py", line 25, in <module>
+    assert client.connected
+           ^^^^^^^^^^^^^^^^
+AssertionError
+
+```
+While the server is outputting:
+```bash
+(venv) danesabo@BeagleBone:~/beaglebone$ python3 simple_server.py 
+DEBUG:asyncio:Using selector: EpollSelector
+DEBUG:pymodbus.logging:Awaiting connections server_listener
+WARNING:pymodbus.logging:Failed to start server [Errno 99] error while attempting to bind on address ('192.168.6.1', 5020): cannot assign requested address
+INFO:pymodbus.logging:Server listening.
+
+```
+
+I need to dig into why this is happening. I'm not really sure why. Either way, I suspect the default IP route might have something to do with it. Maybe there is some way I can explicitly define a network interface.
