[erlang-questions] Setting packet option in ranch

[Loïc Hoguin]

Transport:setops(Socket, [{packet, 4}]) at the start of your protocol code.

The reason you cannot set it when starting the listener is because that 
configuration ought to be independent of the protocol, and packet 
options are protocol-dependent.

Cheers,
