Subject: | [Discuss-gnuradio] Multiple hackrfs |
Date: | Sun, 06 Mar 2016 16:25:06 -0800 |
I’m trying to implement 2 hackrfs and so far, and even with the following settings seen in the picture at the bottom: Osmocom Source properties: Complex float 32 Device Arguments: hackrf=0[,buffers=32][,bias=0][,bias_tx=0] hackrf=1[,buffers=32][,bias=0][,bias_tx=0] Mboards: 2 Num Channels: 2 *Anything I’m missing if I want to just stream in the data from 2 hackrfs? FYI: I’m not much of a programmer, so I don’t understand how to expand on the error, or be able to back trace the location of where the program encountered the error. I’ve tried the following: 1. double checked: - number of Mboards - Num Channels - Device Arguments and their format based on the documentation of the osmocom source and http://sdr.osmocom.org/trac/wiki/GrOsmoSDR under HackRF Source/Sink (only changes I’ve made since running a single hackrf) 2. Google searched the error: FATAL: bad lexical cast: source type value could not be interpreted as target I can’t seem to find anything that seems to makes sense. 3. I have also tested the source with only a single hackrf and set: Mboards: 1 Num Channels: 1 Device Arguments: hackrf=0[,buffers=32][,bias=0][,bias_tx=0] Error output is the same as below except GRC is only trying to fill up 1 missing channel with a null source If anyone can help, that would be awesome, thanks!
