I've merged skipzones' fork into master. This fixes two issues one of which caused me to give up on SdrDx which is a shame because it's a really nice SDR program. If done some small amount running the current SdrDx beta (2.20m) and it crashes infrequently enough to be usable with this server.
This is a fork of Paul Colby's TCP/IP server for the RFSpace SDR-IQ software- defined radio receiver. Significant modifications in this repo include:
- Accept connections from remote hosts
- Comments and prints to help understand how the code works
Tested on a Raspberry Pi 4 with a remote connection from SdrDx on macOS.
Below is Paul's README for the project.
Provide a replacement for the USB to TCP/IP server, siqs_ftdi, formally provided by the CuteSdr software bundle on Ubuntu. siqs_ftdi was need to run my SDR-IQ USB radio with software which talks TCP/IP, like CuteSdr and SdrDdx.
The current server is specialized to the SDR-IQ though the SDR-14 and SDR-IP might also work with small mods. The primary changes required would be to Listener.findRadio which assumes my one and only SDR-IQ exists, and to the cold boot feature for the SDR-IQ. When a hard reset is done, the SDR-IQ loses all memory of the AD6620 DSP program. I detect this state by reading the current frequency which always comes up 680000 Hz. Who knows what other radios might do? Anyway. This warm boot can be disabled by command line switch settings
The server is written in python 3. It is highly recommended to use virtual python environments. Reason being as one adds python libraries to the environment one risks only screwing the environment up and not the Version of python that make your system software run. Virtual environments can be deleted and remade at will.
python3 -m venv <my-env-dir>
source <my-env-dir>/bin/activate
pip install numpy pylibftdi
On MacOS one will need homebrew installed. Python libraries usually wrap c or c++ libs which will need to be installed to be called. The ones I use that come to mind are,
libftdi libusb
These are interdependent cause libftdi uses libusb so. On linux there is the
usual sudo apt install libftdi. Basically, do what it takes on your system
to get Python 3 with a working pylibftdi module.
Okay, at this point one needs to edit the first line in server.py so that it points to your virtual python environment.
#!<full-path-to-my-env-dir>/bin/python
Also, the file server.py should be made executable
On linux or MacOS one calls up a shell and types
./server.py [-b][-r <radio>][-v]
If a radio is not plugged into USB, the server terminates. The optional command line switches are,
-b for disabling the cold boot option. On power up or hard reset, the SDR-IQ
resets memory. -b is provided to skip the cold boot detect.
-r <radio> sets the radio name which will be opened. The default value for
the name is SDR-IQ. Others that might work are, SDR-IP or SDR-14 depending on
the radio being used.
-v selects verbose mode which prints reassuring calming helpful messages.
