- In SDRangel connect the Frequency Tracker plugin by clicking on the grey square at the left of the top bar of the Frequency Tracker GUI. It opens the channel settings dialog. Check the 'Reverse API' box. Next to this box is the address and port at which the channel will be connected. If you use the defaults for `freqtracking.py` you may leave it as it is else you have to adjust it to the address and port of `freqtracking.py` (options `-A` and `-P`).
- In the same manner connect the channel you want to be controlled by `freqtracking.py`. You may connect any number of channels like this. When a channel is removed `freqtracking.py` will automatically remove it from its list at the first attempt to synchronize that will fail.
<h2>ptt_active.py</h2>
<h2>ptt_feature.py</h2>
PTT (Push To Talk) actively listening system. For a pair of given device set indexes it actively listens to start and stop commands on the corresponding devices to switch over to the other
Control a PTT feature and optionally a LimeRFE feature in coordination.
Options are:
- `-h` or `--help` show help message and exit
- `-A` or `--address` listening IP address. Default `0.0.0.0` (all interfaces)
- `-P` or `--port` listening port. Default `8000`
- `-p` or `--port-sdr` SDRangel instance REST API listening port. Default `8091`
- `-l` or `--link` Pair of indexes of the device sets to link. Default `0 1`
- `-d` or `--delay` Switch over delay in seconds. Default `1`
- `-f` or `--freq-sync` Synchronize devices center frequencies
- `-a` or `--address` address and port of SDRangel instance API. Default: 127.0.0.1:8091
- `-p` or `--ptt-index` PTT feature index. Mandatory
- `-l` or `--limerfe-index` LimeRFE feature index. Optional if present synchronizes the PTT and LimeRFE features
- `-t` or `--transmit` Switch to transmission if not present switches to reception
Normal sequence of operations:
In this example we have a Rx device on index 0 and a Tx device on index 1. All settings are assumed to be the default settings.
- Start `ptt_active.py` in a terminal
- On the Rx device right click on the start/stop button and activate reverse API at address `127.0.0.1` port `8000` (default)
- On the Tx device right click on the start/stop button and activate reverse API at address `127.0.0.1` port `8000` (default)
- Start the Rx or Tx device
- Stop the running device (Rx or Tx) this will switch over automatically to the other
Important: you should initiate switch over by stopping the active device and not by starting the other.
In order for it to work properly you should start your SDRangel instance in reception mode with Rx and PTT feature running and set to control the desired Rx and Tx devices.

''' Active PTT
Handles the switchover between two arbitrary device sets
- Both device sets should have the reverse API feature set with the address and port of this server
- Once in place and you have started one of the devices you should only stop one or the other never start
There are two reasons for this:
- This module reacts on an action already taken so if you start Tx then the Rx is not stopped immediately
and damage to the Rx could occur. If you start with a stop action you cannot get in this situation.
- For half duplex devices (only the HackRF) it will lock Tx or Rx. You can always recover the situation
by stopping the running side.
- There is no assumption on the Rx or Tx nature you may as well switchover 2 Rx or 2 Tx
- Both devices have not to belong to the same physical device necessarily. You could mix a RTL-SDR Rx and a
HackRF Tx for example
- It can pilot a LimeRFE device via USB through SDRangel API (by giving TTY device with --limerfe-dev parameter)
and with the assumption that the first device set index given in the --link parameter is the Rx and the second
is the Tx
