Re: [Discuss-gnuradio] why can't use iwconfig when I run the gr-ieee802-11

Hi Bastian, Thanks for reply. I know they are two different values. 5M is for the physical layer and 115K bits/s is for the application layer. The application layer's upper bound should be the physical layer. So the value of application layer should always be less than the physical layer' s.

Hi , I made a mistake. The unit of the throughput is wrong. It should be Kb/s. And I wrote a TCP client and server to run over the gr-ieee802-11. I set the sample rate to 5M so that no O errors and the packet lost rate is only 3%. Also I choose the BPSK1/2 encoding. The throughput is only 115K

Yes, you should be able to start and stop streaming using timed commands on the E310. Are you using the Release 4 image? --​Neel Pandeya On 5 June 2017 at 11:54, Marcus Müller wrote: > Hi Jessica, > > not 100% sure you're right about timed commands not being

Re: [Discuss-gnuradio] Complex numbers in math operations

2017-06-09 Thread Michael Dickens
Hi Vipin - You're doubly dereferencing IdealFMCW. I think your code should read:{{{ *Tx1 = *Tx1 + (IdealFMCW[tapIdx]) * (*hTx1); }}} because the [tapIdx] already dereferences the gr_complex* (IdealFMCW) to be just gr_complex. The error provided by your compiler isn't very helpful. Clang's

Re: [Discuss-gnuradio] Complex numbers in math operations

2017-06-09 Thread Marcus Müller
That's not the multiplication "*", that's an operator that takes only one argument (hence, "operand type is", singular). Point being IdealFMCW[tapIdx] is already a (reference to) a bare gr_complex, NOT a gr_complex* ! Best regards, Marcus On 09.06.2017 07:57, Vipin Sharma wrote: > I have a

Please don't use WX Gui widgets for new designs. We're deprecating them, and they are NOT part of the oncoming GNU Radio 3.8 release. Use Qt instead. We simply have no-one to maintain the WX GUI elements, and thus, it'll be very hard to help you with WX issues. Best regards, Marcus On

That, or make extensive use of hierarchical blocks! You can put subgraphs into separate GRC documents, set the "Generate Options" to "hierarchical block". Things will appear in the block list once you hit the "generate" button. Best regards, Marcus On 09.06.2017 15:20, Dan CaJacob wrote: >

You can't manage the lines manually, but you can probably make things closer to what you want by using virtual sources and sinks. On Fri, Jun 9, 2017 at 1:52 AM Vipin Sharma wrote: > I have an application with multiple blocks in the GUI. When I finish > connecting
