Good evening everybody! Regarding this: "...PS: I found that the "Message Pair to Var" block is not very flexible, since it only allows to set one specific variable...."
Actually a variable can also be a dictionary: simply creates a dictionary in which tag/value pairs refer to other variables. In a mine (never finished) project I'm using this to transfer several settings (TX_freq, RX_freq, various gains, PTT) between a remote RF head (Pluto+ and amplifiers) and a local CONTROL unit, over ZMQ sockets with very good results I hope it can be helpful...
