Sending data to a server

I’m trying to send my recordings from a USRP Source(hardware: NI B200)
to a
database I set up. I have been searching the internet for hours and I
have
come up with nothing. There was one post that mentioned it, but only the
fact that there is a way to have MySQL and GRC working together. Is
there a
way to have the data output from a UHD: USRP Source go to a MySQL
database?
I tried using a TCP Sink, mode: Client but nothing happens and mode:
Server
gives me an error.

Yeah, write a script to insert it into a database. Start by importing
gr and pyodbc…

Which is just about as unhelpful as your question. But seriously:

  • what do you intend to record? (raw samples, filtered signal, decoded
    messages, …)
  • how much data do you plan to record, and how long do you need to store
    it?
  • do you need to store any metadata? (frequency, bandwidth, time,
    location, …)
  • what does your database schema look like?
  • how do you plan on retrieving the recordings from the database?
  • what do you plan on doing with the recording after you get it from
    the database?
  • are you maybe doing it wrong? would it make more sense to just store
    capture files on disk, and keep metadata (including filename) in the
    database?

GDB has a ‘break’ feature; why doesn’t it have ‘fix’ too?

Thank you for responding. I’m new to all of this, including database. I
am
recording what you called metadata; time, location, frequency, power for
about 30 minutes. I think that also answer the question about schema. I
just started learning how to write functions in python, and I went
through
the example tutorials.

That doesn’t necessarily answer the question about schema - you could
have a whole bunch of columns, one for each frequency bin across a
band, or a shorter record of power level on a frequency at a
particular time.

Have a look at uhd_spectrum_sense.py for a start. It emits text
records with many of these measurements - try write a script to parse
the output and stash it into a database. When you get that working
you’ll probably understand how to add database logging to
uhd_spectrum_sense.py.

Thank you. i ran uhd_spectrum_sense.py and it helped alot. I am now in
the
process of getting it to also print out the location in longitude,
latitude, and altitude.

*usrp_spectrum_sense.py

How would uhd_spectrum_sense know your location?
