Dear all, dear developers,  
I have no idea how to get responses back when I send commands to OpenBCI Ganglion.

I am using [pyOpenBCI](https://github.com/OpenBCI/pyOpenBCI).  
When I call for example:

```
`OpenBCIGanglion::write_command(self, command)`

```

how do I read the answer coming from the board?

```
board = OpenBCIGanglion()
response = board.write_command('?') # response is always {'rsp': ['wr']} for any command sent

```

When I send “`?`”, I would like to get back the the board’s registry.  
When I send “`~~`”, I would like to get back “`Sample rate is someHz`”  
([GanglionSDK](https://docs.openbci.com/docs/03Ganglion/GanglionSDK))

I looked for examples, but I couldn’t find any implementation.

Could anyone paste here a code snippet? or pseudo-code…  
Or a reference to a piece of code in the library with some explainations.  
I would appreciate.

I think it would be nice to have a native python library for Ganglion boards (I am trying to build yet one).  
Thanks for the support!

Kind Regards  
Matteo M.
