libgs_ops.scheduling.Communication

class libgs_ops.scheduling.Communication(cmd, retries=3, wait=True)

This class holds the message (fully encoded) that is sent to the satellite.

It is just a convenience class that wraps and populates a dictionary properly for use by the other classes in this module.

It can be constructed with either a HEX string or a bytearray and will automatically compute the other. After construction it will be a dictionary with the following fields:

• hexstr: Hex representation of byte stream
• barray: bytearray represenation of bytestream
• retries: Number of retries
• wait: Whether to wait for reply

Parameters:

• cmd (basestring or bytearray) – Command string (fully encoded) to send to satellite.
• retries (int) – Number of times the command should be retried in case of failure
• wait (bool) – Whether the ground station should wait for a reply from the satellite or not.

Methods

to_dict()

Convert the class to a serialisable python dictionary format (gets rid of the bytearray entry).
