Mosquitto MQTT publish hexadecimal message ?

[Martinez Benjamin]

Hello,
I am facing a problem and maybe someone here will be able to help me.
I am using mosquitto MQTT and I am trying to find a way to give the mosquitto_pub an hexadecimal value, when I send as parameter -m '11223344' it is sending the value in ASCII, same when sending -m 11223344, I also tried to put 11223344 in a file and to send -f myfile but the payload is still in ASCII.
Does anyone have been facing the same problem?

Thanks,

Benjamin.

You can do something like this:

echo -ne "\x45\x23\x43" | mosquitto_pub -h test.mosquitto.org -t 'test/binary' -s
