The manual page does, however, reference 2 examples of how to implement the header generator, and two examples on how to use it (tx_ofdm.grc and rx_ofdm.grc). Cheers, Martin On 03/31/2016 12:46 PM, Miguel Santos wrote: > No, it wasn't, as it doesn't say how to use "Formatter Object". > Thanks fo

No, it wasn't, as it doesn't say how to use "Formatter Object". Thanks for your answer. On 31-03-2016 19:24, Martin Braun wrote: > Was the manual page any help? > > http://gnuradio.org/doc/doxygen/page_packet_data.html > > M > > On 03/31/2016 04:11 AM, Miguel Santos wrote: >> Hi all, >> I want to

Hi all, I want to add a preamble to my data and I started to explore the "tx_ofdm.grc" example, but I have no idea on what to use on "Formatter Object" attribute from Packet Header Generator. Can anyone explain it to me? I'm trying here (https://gnuradio.org/doc/doxygen/classgr_1_1digital_1_1pa

Hi Martin, Thank you. 1.Why the packet length should be larger than 32 bits?Can you explain it? 2.For example,I'm using the OFDM example in gnuradio.If i want to have a working CRC,I must set the length>=4?Is 4 OK? 3.Is the packet length means that the original length(for example len=a) or

Hello everyone, I have 3 questions want to ask you,thanks. 1.I look at this in the api, Uses the following header format: Bits 0-11: The packet length (what was stored in the tag with key len_tag_key) Bits 12-23: The header number (counts up everytime this function is called) Bit 24-31: 8-Bit
