I reformatted your code using triple backticks (see [Please read: make it easier to help you](https://discourse.julialang.org/t/psa-make-it-easier-to-help-you/14757)).

Normally you will use some [serialization](https://docs.julialang.org/en/v1.6/stdlib/Serialization/) (`serialize` and `deserialize`) to transmit data via an UDP socket (See also [GitHub - JuliaIO/JSON.jl: JSON parsing and printing](https://github.com/JuliaIO/JSON.jl)). Can `reinterpret` work in your case? Transmission over UDP is done in `UINT8`.
