Hello all, I'm new to GNU Radio and have a question that I hope more experienced users will find straightforward.
I've successfully managed to create a flow graph that accepts an *infinite *stream of complex samples from an RTL-SDR source block. However, I only require 32,768 samples in total. Once the required number of samples have been received, the flow graph should write these samples (and only this number of samples, no more, no less) to a binary file. Is there an easy way to restrict the number of samples received in this way? I've looked at the documentation for the Message Passing and Stream Tagging APIs, but I'm not sure if they can be used to achieve the desired behaviour. As mentioned above, I'm using the RTL-SDR source block, but I'm guessing the same could be applied to any source block? Thanks in advance for you help! Michael Dilmore
