Hi! Only blocks connected to the global top block get run; your no inputs/no outputs hier block doesn't get connected to the global top block, and thus, neither do the "contained" blocks. Best regards, Marcus PS: You're running GNU Radio 3.7, time to update to 3.8 :) On 20.08.20 23:05, Mirelle

File Source in Hierarchical Block

2020-08-20 Thread Mirelle DeSpain
*Problem and Question* It seems that a file source in a hierarchical block doesn't start automatically as it does in a top block. I ran into this problem with a larger block of code, but was able to isolate it. I tested with both a number sink and a file sink and neither showed any activity coming

Johannes, The 140 came from this datasheet https://www.ettus.com/wp-content/uploads/2019/01/USRP_N310_Datasheet_v3.pdf It does indicate that this is probably a worst case scenario, and that UHD software would improve it. My flow graph has two separate parts, one for the TX that goes to a USRP

Hi Martin, Thanks for the response! The OOT module compiles when I do: cmake ../ and make, however, the QA test fails and gave the following error warnings File "" (for different lines in this imported file) Now what is also disconcerting is that if I try to run another QA test that previous

George, all the usual linking and compilation rules of C++ apply. There are plenty of blocks that call other functions from general_work() or work(). If you're compiling a-OK, then you're probably halfway there. Your QA code should tell you what's missing, if it's a missing symbol (i.e. linker
