`pysbf2` is an original Python 3 parser for the SBF &copy; protocol. SBF is a proprietary binary protocol implemented on Septentrio &trade; GNSS receiver modules. `pysbf2` can also parse NMEA 0183 &copy; and RTCM3 &copy; protocols via the underlying [`pynmeagps`](https://github.com/semuconsulting/pynmeagps) and [`pyrtcm`](https://github.com/semuconsulting/pyrtcm) packages from the same author - hence it covers all the common protocols that Septentrio SBF receivers are capable of outputting.

The `psbf2` homepage is located at [https://github.com/semuconsulting/pysbf2](https://github.com/semuconsulting/pysbf2).

This is an independent project and we have no affiliation whatsoever with Septentrio.

`pysbf2` is compatible with Python >= 3.10. In the following, `python3` & `pip` refer to the Python 3 executables. You may need to substitute `python` for `python3`, depending on your particular environment (*on Windows it's generally `python`*).

The recommended way to install the latest version of `pysbf2` is with [pip](http://pypi.python.org/pypi/pip/):

```shell
python3 -m pip install --upgrade pysbf2
```

If required, `pysbf2` can also be installed into a virtual environment, e.g.:

```shell
python3 -m venv env
source env/bin/activate # (or env\Scripts\activate on Windows)
python3 -m pip install --upgrade pysbf2
```

For [Conda](https://docs.conda.io/en/latest/) users, `pysbf2` is also available from [conda forge](https://github.com/conda-forge/pysbf2-feedstock):

## <a name="reading">Reading (Streaming)</a>

```
class pysbf2.SBFreader.SBFReader(stream, *args, **kwargs)
```

You can create a `SBFReader` object by calling the constructor with an active stream object. 
The stream object can be any viable data stream which supports a `read(n) -> bytes` method (e.g. File or Serial, with 
or without a buffer wrapper). `pysbf2` implements an internal `SocketWrapper` class to allow sockets to be read in the same way as other streams (see example below).

Individual input SBF, NMEA or RTCM3 messages can then be read using the `SBFReader.read()` function, which returns both the raw binary data (as bytes) and the parsed data (as a `SBFMessage`, `NMEAMessage` or `RTCMMessage` object, via the `parse()` method). The function is thread-safe in so far as the incoming data stream object is thread-safe. `SBFReader` also implements an iterator.

The constructor accepts the following optional keyword arguments:

* `protfilter`: `NMEA_PROTOCOL` (1), `SBF_PROTOCOL` (2), `RTCM3_PROTOCOL` (4). Can be OR'd; default is `NMEA_PROTOCOL | SBF_PROTOCOL | RTCM3_PROTOCOL` (7)
* `quitonerror`: `ERR_IGNORE` (0) = ignore errors, `ERR_LOG` (1) = log errors and continue (default), `ERR_RAISE` (2) = (re)raise errors and terminate
* `validate`: `VALCKSUM` (0x01) = validate checksum (default), `VALNONE` (0x00) = ignore invalid checksum or length
* `parsebitfield`: 1 = parse bitfields ('X' type properties) as individual bit flags, where defined (default), 0 = leave bitfields as byte sequences

Example -  Serial input. This example will output both SBF and NMEA messages but not RTCM3:
```python
from serial import Serial
from pysbf2 import SBFReader, NMEA_PROTOCOL, SBF_PROTOCOL
with Serial('/dev/ttyACM0', 115200, timeout=3) as stream:
  ubr = SBFReader(stream, protfilter=NMEA_PROTOCOL | SBF_PROTOCOL)
  raw_data, parsed_data = ubr.read()
  if parsed_data is not None:
    print(parsed_data)
```

Example - File input (using iterator). This will only output SBF data:
```python
from pysbf2 import SBFReader, SBF_PROTOCOL
with open('SBFdata.bin', 'rb') as stream:
  ubr = SBFReader(stream, protfilter=SBF_PROTOCOL)
  for raw_data, parsed_data in ubr:
    print(parsed_data)
```

Example - Socket input (using iterator). This will output SBF, NMEA and RTCM3 data:
```python
import socket
from pysbf2 import SBFReader, NMEA_PROTOCOL, SBF_PROTOCOL, RTCM3_PROTOCOL
with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as stream:
  stream.connect(("localhost", 50007))
  ubr = SBFReader(stream, protfilter=NMEA_PROTOCOL | SBF_PROTOCOL | RTCM3_PROTOCOL)
  for raw_data, parsed_data in ubr:
    print(parsed_data)
```

---
## <a name="parsing">Parsing</a>

You can parse individual SBF messages using the static `SBFReader.parse(data)` function, which takes a bytes array containing a binary SBF message and returns a `SBFMessage` object.

**NB:** Once instantiated, a `SBFMessage` object is immutable.

The `parse()` method accepts the following optional keyword arguments:

* `validate`: VALCKSUM (0x01) = validate checksum (default), VALNONE (0x00) = ignore invalid checksum or length
* `parsebitfield`: 1 = parse bitfields ('X' type properties) as individual bit flags, where defined (default), 0 = leave bitfields as byte sequences

Example - output (GET) message:
```python
from pysbf2 import SBFReader
msg = SBFReader.parse(b"$@^b\xa6\x0f`\x00X\x9bs\x0c?\t\x01\x00\x1d\x0eX\x17\xfc\x04MA\xe6\xe4\x8b\xe6\xea)\x02\xc1\x98\x19(\xb2\x18uSA\xa6\xddABQ\x90\x018\xb4\x86q:\xc0\x93\x85\xbb\xf9\x02\x95\xd0\xe3\xaf\xe6nKl\xde?\x03\xe0V>\x00\x00\x10\x00\x8f\x02\x8f\x02\r\t2P\x01\x00\x00\x00+\x00z\x00\x88\x00`\x01")
print(msg)
```
```
<SBF(PVTCartesian, TOW=10:01:25, WNc=2367, Type=1, Reserved1=0, AutoSet=0, 2D=0, Error=0, X=3803640.1823747293, Y=-148797.3625715144, Z=5100642.783697508, Undulation=48.466453552246094, Vx=3.0890401831129566e-05, Vy=0.000921349273994565, Vz=-0.004076451063156128, COG=-20000000000.0, RxClkBias=0.47535978155315045, RxClkDrift=0.20983891189098358, TimeSystem=0, Datum=0, NrSV=16, WACorrInfo=0, ReferenceID=655, MeanCorrAge=655, SignalInfo=1345456397, RAIMIntegrity=1, GalHPCAFail=0, GalIonStorm=0, Reserved2=0, NrBases=0, PPPSeedAge=0, Reserved3=0, PPPSeedType=0, Latency=43, HAccuracy=122, VAccuracy=136, BaseARP=0, PhaseCtrOffset=0, Reserved4=8, ARPOffset=1)>
```

If `parsebitfield=False`, the message is parsed without individual bit flags, e.g.:
```
<SBF(PVTCartesian, TOW=10:01:25, WNc=2367, Mode=b'\x01', Error=0, X=3803640.1823747293, Y=-148797.3625715144, Z=5100642.783697508, Undulation=48.466453552246094, Vx=3.0890401831129566e-05, Vy=0.000921349273994565, Vz=-0.004076451063156128, COG=-20000000000.0, RxClkBias=0.47535978155315045, RxClkDrift=0.20983891189098358, TimeSystem=0, Datum=0, NrSV=16, WACorrInfo=0, ReferenceID=655, MeanCorrAge=655, SignalInfo=1345456397, AlertFlag=b'\x01', NrBases=0, PPPInfo=b'\x00\x00', Latency=43, HAccuracy=122, VAccuracy=136, Misc=b'`')>
```

The `SBFMessage` object exposes different public attributes depending on its message type or 'identity',
e.g. the `PVTCartesian` message has the following attributes:

```python
print(msg)
print(msg.identity)
print(msg.X, msg.Y, msg.Z)
```
```
<SBF(PVTCartesian, TOW=10:01:25, WNc=2367, Type=1, Reserved1=0, AutoSet=0, 2D=0, Error=0, X=3803640.1823747293, Y=-148797.3625715144, Z=5100642.783697508, Undulation=48.466453552246094, Vx=3.0890401831129566e-05, Vy=0.000921349273994565, Vz=-0.004076451063156128, COG=-20000000000.0, RxClkBias=0.47535978155315045, RxClkDrift=0.20983891189098358, TimeSystem=0, Datum=0, NrSV=16, WACorrInfo=0, ReferenceID=655, MeanCorrAge=655, SignalInfo=1345456397, RAIMIntegrity=1, GalHPCAFail=0, GalIonStorm=0, Reserved2=0, NrBases=0, PPPSeedAge=0, Reserved3=0, PPPSeedType=0, Latency=43, HAccuracy=122, VAccuracy=136, BaseARP=0, PhaseCtrOffset=0, Reserved4=8, ARPOffset=1)>

```

Decodes for various coded attributes (e.g. PVT `Type` or MeasEpoch `SigIdxLo`) are provided in [`sbftypes_decodes.py`](https://github.com/semuconsulting/pysbf2/blob/main/src/pysbf2/sbftypes_decodes.py):
```python
from pysbf2 import PVT_TYPE
print(PVT_TYPE[msg.Type]) # msg.Type = 4
```
```
"RTK with fixed ambiguities"
```
```python
from pysbf2 import SIGNAL_TYPE
sigtype = SIGNAL_TYPE[msg.SigIdxLo_02] # msg.SigIdxLo_02 = 2
print(f"Frequency = {sigtype[2]} MHz, RINEX Code = {sigtype[3]}") 

```
```
Frequency = 1227.6 MHz, RINEX Code = 2W
```

The `payload` attribute always contains the raw payload as bytes. Attributes within repeating groups are parsed with a two-digit suffix (PRNMaskNo_01, PRNMaskNo_02, etc.).

**Tip:** To iterate through a repeating group of attributes (*e.g. PRNMaskNo*), the following construct can be used:

```python
vals = [] # list of PRNMaskNo values from repeating group
for i in range(msg.N): # N = size of repeating group
    PRNMaskNo = getattr(msg, f"PRNMaskNo_{i+1:02d}")
    vals.append(PRNMaskNo)
print(vals)
```

## <a name="generating">Generating</a>

```
class pysbf2.SBFmessage.SBFMessage(SBFClass, msgid: int, revno: int, **kwargs)
```

You can create a `SBFMessage` object by calling the constructor with the following parameters:
1. message id
2. revision number (optional, defaults to 0)
3. (optional) a series of keyword parameters representing the message payload

The 'message class' and 'message id' parameters may be passed as lookup strings, integers or bytes.

The message payload can be defined via keyword arguments in one of three ways:
1. A single keyword argument of `payload` containing the full payload as a sequence of bytes (any other keyword arguments will be ignored). **NB** the `payload` keyword argument *must* be used for message types which have a 'variable by size' repeating group.
2. One or more keyword arguments corresponding to individual message attributes. Any attributes not explicitly provided as keyword arguments will be set to a nominal value according to their type.
3. If no keyword arguments are passed, the payload is assumed to be null.

Example - to generate a PVTCartesian message, any of the following constructor formats will work:

A. Pass entire payload as bytes:
```python
from pysbf2 import SBFMessage
msg1 = SBFMessage("PVTCartesian", payload=b'X\x9bs\x0c?\t\x01\x00\x1d\x0eX\x17\xfc\x04MA\xe6\xe4\x8b\xe6\xea)\x02\xc1\x98\x19(\xb2\x18uSA\xa6\xddABQ\x90\x018\xb4\x86q:\xc0\x93\x85\xbb\xf9\x02\x95\xd0\xe3\xaf\xe6nKl\xde?\x03\xe0V>\x00\x00\x10\x00\xff\xff\xff\xff\r\t2P\x01\x00\x00\x00+\x00\xc4\x04V\x05`')
print(msg1)
```
```

The SBF protocol is principally defined in the modules `sbftypes_*.py` as a series of dictionaries. Message payload definitions must conform to the following rules:

```
1. attribute names must be unique within each message class
2. attribute types must be one of the valid types (I1, U2, X4, etc.)
3. if the attribute is scaled, attribute type is list of [attribute type as string (I1, U2, etc.), scaling factor as float] e.g. {"lat": [I4, 1e-7]}
4. repeating or bitfield groups must be defined as a tuple ('numr', {dict}), where:
   'numr' is either:
     a. an integer representing a fixed number of repeats e.g. 32
     b. a string representing the name of a preceding attribute containing the number of repeats e.g. 'numCh'
     c. an 'X' attribute type ('X1', 'X2', 'X4', etc) representing a group of individual bit flags
   {dict} is the nested dictionary of repeating items or bitfield group
```

Repeating attribute names are parsed with a two-digit suffix (PRNMaskNo_01, PRNMaskNo_02, etc.). Nested repeating groups are supported. See "MeasEpoch" way of example.

An SBF message's content (payload) is uniquely defined by its ID (message ID and revision number); accommodating the message simply requires the addition of an appropriate dictionary entry to the `sbftypes_blocks.py` module.
