Hi Martin,
I have put the following code into my block.
d_rxCommand = pmt::make_dict();
d_rxCommand = pmt::dict_add(d_rxCommand, pmt::mp("time"),
pmt::mp(0.5));
message_port_pub(pmt::mp("rx_freq_msg"), d_rxCommand );
It sends the message to the UHD Sink. But I get this error at run time:
thread[thread-per-block[5]: <block gr uhd usrp source (1)>]: pmt_cdr:
wrong_type : 1
Any ideas ? I am trying to auto step the frequencies, and currently have my own
block to generate frequency messages which works fine. I am now trying to
implement the time commands. Is there any other way to do it ?
Thanks,
Nigel

Subject: Re: [Discuss-gnuradio] gr-uhd timed command messages
When using messages, simply add a 'time' key to the command dictionary, and it
will be set for the command you're calling. The time stamp value, is a
long/double pair, for full and fractional time. Example:
{'freq': 1e9, 'time': (100, 0.1)}
If this is your message, it will set the frequency to 1 GHz at time 100.1.
Cheers,
Martin
