Hello,
I have a flowgraph that send ZMQ PUB messages generated by a custom
OOT block. The messages transmitted by GNURadio ZMQ PUB block are
received by a Python application, using a standard ZMQ Library.
[custom_oot_block] ---(GNURadio message)---> [ZMQ Publisher]
.....(ethernet).....> [Python ZMQ SUB Library]
This is the part of the code of the OOT block that creates the message:
-----
float *outPdPfa = (float *) output_items[0];
pmt::pmt_t msg = pmt::init_f32vector(1, outPdPfa);
message_port_pub(pmt::mp("hard_decision"), msg);
-----
In Python, I receive the transmitted message and this is some of the
strings that are received:
'\n\x08\x00\x00\x00\x01\x01\x00?\xe4\xbe\x83\x00\x00\x00\x00'
'\n\x08\x00\x00\x00\x01\x01\x00?\xe5R\xb5 \x00\x00\x00'
'\n\x08\x00\x00\x00\x01\x01\x00?\xe4B0\xa0\x00\x00\x00'
'\n\x08\x00\x00\x00\x01\x01\x00?\xe4\xa3\\\xa0\x00\x00\x00'
'\n\x08\x00\x00\x00\x01\x01\x00?\xe5jV\xa0\x00\x00\x00'
'\n\x08\x00\x00\x00\x01\x01\x00?\xe4\xf8\x00\x00\x00\x00\x00'
'\n\x08\x00\x00\x00\x01\x01\x00?\xe4\x90\x00\x00\x00\x00\x00'
How do I convert these strings to a floating number value?
Thank you.
Regards,
Daniel
