@ramy_rutu please have a look at your post, i think there is something wrong with your markdown (definition of how the post should look like).
Mostly the bad format comes from copy code and then add the fences by pressing the button. Always first set the code fence and then copy the code into it.
- Can you download and the standart
433Utils/RPi_utilsand compile withmake? - Can your run
./send xxxor./RFSniffer? - Then copy the
RFmqtt.cppto the folderRPi_utilsand add the additional line to the makefile. - install the libraries
sudo apt-get install libmosquitto-dev - execute
make
Please comment each of these steps and what result you get.
