+## Setup commands
+- this projects uses poetry for package management 
+- if something should be run in a python env use 'poetry run'
+
+# Environment
+- this application normally runs on an embedded linux on a cm4
+
+## Application
+- this is a bluetooth Auracast transmitter application
+- if you add a new parameter for a stream make sure it is saved to the settings.json so it is persisted
+- it consists of multicast_frontend.py and multicast_server.py mainly which connect to each other via a rest api
+- after you implemented something the user will mainly test it and you should call the update_and_run_server_and_frontend.sh script if the server and frontend were already running.

+PTP TIMESTAMPING TEST TOOL OVERVIEW
+===================================
+
+ptp_timestamping_test is a standalone tool that can be used independently of DEP
+itself to do a definitive check of a network driver's timestamping capabilities.
+
+After installing DEP, this tool should ALWAYS be run before starting DEP for the
+first time. This is to ensure that the driver(s) for the selected network interface(s)
+are able to properly timestamp all PTP event packets using the required timestamping
+mode (i.e. hardware, PTPv1-only hardware or software).
+
+If problems are found with the driver(s) when timestamping in a given mode, DEP
+should NOT be started in that mode, as otherwise PTP will either fail to start
+or will experience synchronisation issues.
+
+In such a case, in order to run DEP:
+
+- To continue using the given mode, the driver(s) must be updated and the tool
+  rerun until problems are no longer reported
+- Or, another timestamping mode that shows no problems must be used instead
+
+

+   b. Full test
+3. Running tests

+6. Test behaviour and duration
+   a. Test packet receive and send behaviour
+   b. Test duration
+
+
+1. TEST TYPES
+=============
+
+There are two types of tests that can be done with the tool:
+
+1) A preliminary check of whether a driver actually supports configuring a
+   particular timestamping mode. This test tries to create a network socket
+   configured to use the selected mode. The success or failure of this test
+   is a much more reliable indicator of configuration support than the output
+   of 'ethtool -T', as a driver's reported claims are not always 100% accurate.
+   Nevertheless, as a guide to the user the tool gathers and displays the
+   equivalent information shown via 'ethtool -T'.
+
+2) A full test. This uses a configured network socket to send and receive
+   all PTP event packet types, and checks that they all get timestamped. 
+
+A full test is the only real way to determine if timestamping is fully operational.
+A simple preliminary check is NOT a substitute for this.
+
+However, if a timestamping mode fails a preliminary check it means that mode
+CANNOT be used (unless the driver can be updated/rectified).
+
+
+2. TEST REQUIREMENTS
+====================
+
+The tool must always be run as root.
+
+a. Preliminary check
+--------------------
+
+Running a preliminary check has no extra requirements. This check can be done
+at any time.
+
+b. Full test
+------------
+
+The device being tested must be connected to a Dante network. And, in addition 
+to this device:
+
+- At least two Dante devices (one leader, and at least one follower) must be
+  present on the network
+- If AES67 and/or site/domain unicast clocking are going to be used, at least
+  two PTPv2-capable devices (again, one leader and at least one follower) must
+  be present:
+  * At least one of these must be a third-party (i.e. non-Dante) device
+  * Two Dante devices running in AES67 mode are NOT a suitable substitute, as
+    without a third-party device there will be no PTPv2 follower devices
+
+Points of note:
+
+- ALL devices (both Dante and third-party) MUST be in the unmanaged domain (i.e.
+  in the default subdomain for PTPv1, and in domain number 0 for PTPv2)
+- The tool assumes that all PTP traffic is multicast. Therefore, any follower
+  devices configured to use unicast delay requests will not be visible and thus
+  cannot be used
+- If only one device of each PTPv1/PTPv2 type is present (as a leader), the
+  tool can still be run but it will report that the test is incomplete
+- Running the test will NOT cause clock synchronisation to be disrupted on the
+  network
+
+
+3. RUNNING TESTS
+================
+
+a. Via dep_check.sh
+-------------------
+
+dep_check.sh will use the tool to do preliminary checks of all three timestamping
+modes for the interface(s) configured in dante.json. Upon completion, it will
+display a complete command line(s) (with parameters based on the settings in
+dante.json) that the user can run to do a full test(s) for:
+
+- The mode in dante.json, and/or
+- The recommended mode (if different to the above), based on the check results
+
+If the timestamping mode set in dante.json fails a preliminary check, dep_check.sh
+will show a complete command line the user can run to see the full output of the
+check if desired.
+
+
+b. Running manually
+-------------------
+
+Running the tool with the -h option will show how the tool can be used.
+
+As stated above dep_check.sh provides complete command lines for convenience,
+however manual usage is fairly straightforward:
+
+- The value for -i is the interface under "network" in dante.json
+- The timestamping mode can be set as required
+- If "dsaTaggedPackets" in dante.json is set to true, -dsa must be specified
+- If -dsa is used along with either -hw or -hwv1, a value must be supplied
+  for -hwi. This is the entry under "clock.hardwareInterfaces" in dante.json
+  that corresponds to the value supplied for -i
+- By default, the tool will run a full test. Specifying -c will result in the
+  tool running only a preliminary check
+
+
+4. UNDERSTANDING TEST RESULTS
+=============================
+
+a. Preliminary check
+--------------------
+
+The result will be a simple pass or fail, depending on whether a network socket
+could be configured with the chosen settings.
+
+The tool will also display the timestamping capabilities reported by the driver
+(the same ones shown via 'ethtool -T') and indicate whether these match what the
+user wants. HOWEVER, even if the reported capabilities do not match the check
+still proceeds to do a network socket setup by explaining that it MAY succeed-
+in spite of the mismatch.
+
+b. Full test
+------------
+
+For timestamping to be deemed operational, the driver MUST be able to timestamp:
+
+- Both PTP event packet types (SYNC and DELAY_REQ)
+- In both directions
+
+Furthermore, in order to be able to run DEP:
+
+- To use Dante audio, PTPv1 timestamping must fully work
+- To use AES67 with a third-party device and to enable site/domain unicast
+  clocking, PTPv2 timestamping must also work
+
+The test output provides a terse summary of whether timestamping for a particular
+version of PTP was:
+
+- All OK
+- Found to have errors for a particular packet type + timestamping direction
+- Not (completely) tested due to lack of devices present
+
+Refer to the next section for some example full test outputs.
+
+The tool will display detailed results for the packet version + type(s) that
+encountered any timestamping errors. These results provide specific information
+on the number of packets sent/received, the number successfully timestamped and
+how many attempts resulted in errors. This can be useful when debugging a network
+driver. If however, yet more specific details are required about the types of
+errors and/or the relative times at which packet events + timestamping operations
+occur, the logging option can be used. This is discussed further below.
+
+c. Full test output examples
+----------------------------
+
+On a device with a working driver, assuming both PTPv1 and PTPv2 leaders and
+followers are present the output will look like the following:
+
+    # ./ptp_timestamping_test -i eno2 -hw
+    Using interface eno2, with hardware timestamping
+    Checking PHC resolution...
+    Checking PHC read speed... 4283ns (approx.)
+
+    Testing PTP timestamping...
+
+    Testing v1 SYNC packets... OK
+    Testing v1 DELAY_REQ packets... OK
+    Testing v2 SYNC packets... OK
+    Testing v2 DELAY_REQ packets... OK
+
+
+    TEST SUMMARY
+    ============
+
+    PTPv1 all OK
+    PTPv2 all OK
+
+Points of note:
+
+- When using hardware timestamping, the first thing the tool does is perform some
+  measurements of the PHC (PTP Hardware Clock)
+- The approximate read speed of the PHC should be noted. NICs that perform
+  timestamping at the PHY instead of the MAC layer will exhibit very large values
+  here (greater than about 100,000ns), and these are typically unsuitable for use
+  with DEP as the slow read times will adversely affect its PTP accuracy
+
+The outputs below were produced on a board which has problems with hardware
+timestamping (but not software timestamping). Also:
+
+- The Dante network used had two devices
+- One of the devices had AES67 turned on (and so there was a PTPv2 leader
+  present, but no PTPv2 followers)
+
+Software timestamping result:
+
+    # ./ptp_timestamping_test -i eth1
+    Using interface eth1, with software timestamping
+
+    Testing PTP timestamping...
+
+    Testing v1 SYNC packets... OK
+    Testing v1 DELAY_REQ packets... OK
+    Testing v2 SYNC packets... OK
+    Testing v2 DELAY_REQ packets... none detected
+
+
+    TEST SUMMARY
+    ============
+
+    PTPv1 all OK
+    PTPv2 only partially tested - no follower devices detected
+
+Hardware timestamping result:
+
+    # ./ptp_timestamping_test -i eth1 -hw
+    Using interface eth1, with hardware timestamping
+    Checking PHC resolution...
+    Checking PHC read speed... 3928ns (approx.)
+
+    Testing PTP timestamping...
+
+    Testing v1 SYNC packets... OK
+    Testing v1 DELAY_REQ packets... Tx problems
+    Testing v2 SYNC packets... OK
+    Testing v2 DELAY_REQ packets... none detected
+
+
+    TEST SUMMARY
+    ============
+
+    PTPv1 SYNCs OK, errors found with DELAY_REQs - details below
+    PTPv2 only partially tested - no follower devices detected
+
+
+    DETAILED RESULTS
+    ================
+
+    v1 DELAY_REQ
+    ------------
+    Rx packet receive limit: 5
+    Rx packets received: 5
+    Rx packets timestamped: 5
+    Rx packet timestamping errors: 0
+    Rx packets from additional followers received: 0
+    Rx packets from additional followers timestamped: 0
+    Rx packet timestamping errors for additional followers: 0
+
+    Tx packets sent: 5
+    Tx packets timestamped: 0
+    Tx packets with slow timestamps: 0
+    Tx packet timestamping errors: 0
+
+The detailed results show that:
+
+- All Rx packets (up to the default receive limit of 5) from the follower the
+  test chose were successfully timestamped
+- No other followers were present (and so DELAY_REQs from those were not received)
+- No Tx packets were timestamped, HOWEVER there were no errors. This is an
+  indication that the driver did not attempt to timestamp any outgoing v1 DELAY_REQs
+
+For some drivers, timestamping operations do indeed take place BUT result in
+errors. The following detailed results are from a board whose driver produces
+these:
+
+    DETAILED RESULTS
+    ================
+
+    v1 SYNC
+    -------
+    Rx packet receive limit: 20
+    Rx packets received: 20
+    Rx packets timestamped: 0
+    Rx packet timestamping errors: 20
+    Rx FOLLOW-UPs received: 20
+    Multiple leaders detected: no
+
+    Tx packets sent: 20
+    Tx packets timestamped: 20
+    Tx packets with slow timestamps: 0
+    Tx packet timestamping errors: 0
+
+These details show that:
+
+- All 20 (the default receive limit) SYNC packets were indeed received, however
+  none were timestamped
+- Timestamping was attempted each time, but always resulted in an error
+- THere were no issues timestamping outgoing packets
+
+The details in a SYNC report also include network information that may be of
+interest to the user:
+
+- Most PTP leaders issue FOLLOW-UP packets after each SYNC. These do not need
+  to be timestamped, however the tool listens for these and checks that they
+  indeed come from the leader sending the SYNCs. If no FOLLOW-UPs are received,
+  this may indicate either a problematic leader OR the presence of a leader
+  using the one-step rather than the more common two-step synchronisation method
+- If the tool detects more than one leader on the network, it will be indicated
+  here
+
+
+5. USING EVENT + ERROR LOGGING
+==============================
+
+While the full test outputs above point to which timestamping operations fail to
+work, in some cases (e.g. if trying to debug a network driver) a detailed timeline
+of packet and timestamping events, along with the specific errors that occurred,
+can be useful.
+
+By using the -l option along with a file to log to, the tool will produce its
+normal output but also place all events into that file. The logs will contain:
+
+- The start and end of each test
+- Every packet receive and send
+- Every successful timestamp read (Rx/Tx), along with the timestamp value
+- If an error reading a timestamp occurs, a description of the error (ancillary
+  data truncated, no timestamp information, insufficient timestamp data)
+- If timestamping is not taking place at all (as in the example above, for Tx),
+  the log will be missing these events
+
+Each line also starts with a timestamp (seconds and nanoseconds), which is the
+value of CLOCK_REALTIME at the moment an event or error was logged.
+
+NOTE: When running a hardware timestamping test, you will notice that the first
+test in the log is a PTPv1 "scratch" test. This is a throwaway test done at the
+start that, on some devices, will exhibit odd Tx timestamping and/or errors.
+A scratch test is always done because in some cases a driver will only start
+reporting correct timestamps after a few initial socket and timestamp operation
+failures. This way, the actual tests of interest are not affected. The scratch
+test logs can be safely ignored (although initial socket behaviour after setup
+may be of interest to some).
+
+
+6. TEST BEHAVIOUR AND DURATION
+==============================
+
+a. Test packet receive and send behaviour
+-----------------------------------------
+
+The test uses packet receive limits for each PTP event packet type (for both
+protocol versions). By default, these are:
+
+- 20 SYNCs from the first (and ideally only) leader seen
+- 5 DELAY_REQs from the first follower detected
+
+When transmitting packets:
+
+- For a SYNC test, each received SYNC is copied and sent out
+- For a DELAY_REQ, packet sends are throttled if required so that not less than
+  0.25 seconds can elapse before a DELAY_REQ is sent. The sent packet is a copy
+  of the last received DELAY_REQ. DELAY_REQ tests count packets from the first
+  follower detected but otherwise receive and timestamp DELAY_REQs from any and
+  all followers on the network
+
+Each test only ends when:
+
+- The receive limit has been reached, and
+  - For SYNCs, that same number has been sent out
+  - For DELAY_REQs, a minimum of that same number has been sent
+- Or, the test times out waiting for a packet to arrive
+  - For SYNCs, the test will wait 2 seconds before timing out
+  - for DELAY_REQs, this figure is 8 seconds (because it can be up to 7.5 seconds
+    between packet arrivals)
+- Or, a socket error occurs (these should NOT occur unless there is a system
+  issue or network connectivity is suddenly lost)
+
+NOTE: If the test sees no SYNC packets for a particular PTP version, it will
+automatically skip the DELAY_REQ test for that version as, in the absence of a
+leader, there will not be followers sending DELAY_REQs. If no SYNCs are detected
+despite the device being on a populated Dante network (or one with PTPv2 devices),
+it may be the case that multicast PTP traffic is not being sent to this device.
+If this happens, the network and/or switch(es) should be checked to ensure that
+the device receives multicast PTP.
+
+b. Test duration
+----------------
+
+At the default receive limits, a test will last about 25 seconds typically:
+
+- SYNCs from Dante leaders are normally sent every 0.25 seconds
+- DELAY_REQs from Dante followers are sent at varying intervals, but on average
+  are around 4-5 seconds
+
+Note: third-party AES67 devices may have their own packet send intervals
+
+To run a shorter or longer test, the -nsy and -ndr tool options can be used:
+
+- If a driver is known to have working timestamping for a particular packet
+  type but not another, the limit for the working type can be reduced
+- Setting the limit to 0 will skip that packet type entirely (and the full test
+  output will say so, and also warn of an incomplete test)
+- On the other hand, it may be the case that a driver only begins to exhibit
+  problems after running for a while. In this case, the limits can be increased
+  using the send intervals above as a rough guide for determining the approximate
+  test duration
