In case some devices do not complete a job, this makes it possible
to show a warning in the UI showing the amount of devices that did
not complete the job.
This aligns the forward-error-correction code with the LoRa Basics
Modem stack, which seems to be different from the TS004 MATLAB example
code in that it only calls the matrix_line function for the redundancy
frames and thus the n argument ranges from 1 until (and including) the
number of redundancy frames.
The TS004 MATLAB example calls the matrix_line function for every
fragment, thus the n argument ranges from 1 until (and including) m +
the number of redundancy frames. While n <= m, it returns early.
We should filter on error_msg = "" instead of != NULL, as we only would
like to update the error_msg for devices that not yet have an error set.
Else we would overwrite an earlier error message.
These are the same as the v1 struct, buts re-exporting will make the
documentation confusing + will become inconsistent with other app layer
packages that do provide different struct implementations.
In case there are no fuota devices (e.g. all devices failed the previous
step), this will log a warning and the flow will continue with multicast
cleanup and completion steps.
This add the gen_app_key to the device keys which is needed for FUOTA
and adds a random multicast address + key to the fuota deployment. To
the FUOTA job structure, this adds a return msg such that errors can
be captured in the database.
Currently this allows for creating FUOTA dpeloyments and adding to /
removing from devices and gateways. In its current state, it does not
show the status of the FUOTA deployment.
This adds options to auto-calculate the fragment size (based on max.
payload size available for the given data-rate) and multicast
timeout (based on server settings).
This this puts the ABP parameters into a single JSON(B) field, to reduce
the amount of device-profile fields that currently exist. The same work
will be done for Class-B/C and Relay parameters. Once completed, this
means we can drop the diesel '64-column-tables' feature, which will
reduce compile time.
