Re: [Discuss-gnuradio] Problems passing the control between blocks - message passing

Hi John, Also, I am trying to use boost::this_thread::yield() between blocks, but when I add a third block into the chain, the control passes between BLOCK 1 - BLOCK 2. When they finish, the control is passed to BLOCK 3. Thanks again for your suggestions, Jose On Mon, Oct 22, 2012 at 9:17 AM,

[Discuss-gnuradio] Northern hemisphere notice: Winter is approaching

A note for those who receive = 1 GHz and have their antennas outside at 60 North (I'm at +63 North). Water/Ice/Snow will attenuate your signal dramatically if you don't protect your antenna. A sample when air temperature was +2C and dish temperature was -1C (1.5m prime focus).

Re: [Discuss-gnuradio] Very weird about my N210 board.

Sorry for the late reply here, but 1 more thing to check: is the device getting consistent power? We’ve noticed that if the voltage is too low or the connector is loose, the radio can be thrown into a state that produces those errors. From:

Hi Community, In following up this issue, we've tried different options (ie. returns 0, yield or returns -1 in work function). What is happening is the block are running exactly once. In other words, the work() function never comes back and run again. Anyone can suggest a way to solve this

Oh noes, it looks like the pre-cog is overwriting the gnuradio-cores' block_tree.xml. This should probably be renamed to pre_cog_block_tree.xml -josh On 10/22/2012 01:52 PM, Sakib Chowdhury wrote: Hi, I cannot figure out the source of the problem. I don't have multiple installations of

Hi Josh, Do you see an error when you return 0 from work? Like source block returned 0, marking it done? If this is the case, you can update gnuradio to get the fix. A: I returned 0 for every block and in that case, the routines run once only. However, I don't see any error. On the other hand,

Hi, I've a kind of basic question, but it has taken me a lot of time to figure out. I made a signal processing chain of blocks (very simple in facts, generate PSDU then send as a message downstream, manipulate the content and count the number of message that I've received). In order to debug my
