I can't figure out this script issue with my BladeRF #244

For best results, it is not recommended to set both RX and TX to the same frequency. Instead, consider offsetting them by at least 1 MHz and mixing digitally.

For the above reason, 'set frequency ` is deprecated and scheduled for removal in future bladeRF-cli versions.

What am I missing from here? Am I using the wrong FPGA, the wrong firmware? Your answer is very vague.

osqzss commented 4 years ago

If you're using libbladeRF 2.0 or later, try "set gain tx ##" instead of "set txvga1 ##". https://www.nuand.com/frequently-asked-questions/#How_do_I_set_gains https://github.com/Nuand/bladeRF/wiki/bladeRF-CLI-Tips-and-Tricks#Receiving_samples

Thank you! That helps a lot!

It's a bladeRF 2.0 micro is that helps you at all. I just don't know what I'm doing wrong.

My idea was that this script was supposed to work out of the box without any needed tweaks to the script but that does not seem to be the case. I've tried everything I know to try:

[chown@mbp ~/Downloads/gps-sdr-sim-realtime (master *)]$ cat bladerf.script set frequency 1575.42M set samplerate 2.6M set bandwidth 2.5M set agc off set gain rx 60 cal lms cal dc tx tx config file=gpssim.bin format=bin tx start tx wait

osqzss commented 4 years ago

Since I don't have a bladeRF micro 2.0, I can't be of much help.

The error message mentioned about the AGC. Please try disable it with the "set agc off" command. https://nuand.com/forums/viewtopic.php?t=8741

By the way, you need to set TX gain for the simulator, not RX.

Here is what I've tried. I don't know what I'm missing. Sorry I'm a new to all of this.

You can skip "cal lms" and "cal dc tx" lines and see how things go.

Is there a reason why Snapchat doesn't show the new location? Maybe their algorithm has changed a bit? I haven't done this since hackrf days and it used to work fine. Just wondering what you thought. I had tried to play with duration settings thinking maybe it needed to be set longer but that did not help at all. I'm not sure what is happening.

acr92 commented 4 years ago

@chownsauce Can you confirm that you got it to work with a bladeRF 2.0 micro? Is it the A4 or A9 you have? (and does it matter)

With regards to Snapchat, you might fall victim to the Network Location Provider providing a location, and your GPS simulator providing another location. Try to disable the Google Network Location Provider (assuming you're running on Android, on iOS I don't know if it's possible to disable the Apple network location provider). NLP uses WiFi networks and cell towers to provide an approximate location.

hello my friend,have fixed this question caused by bladerf xa4(2.0) ? May i get ur script?
