The previous article showed how to send a value wirelessly from one node to another, as text.
While it’s a good example to start off with due to the simplicity, this doesn’t really scale. It’s tedious to build up text packets, they lead to larger packet payloads, and this all adds to the complexity on both ends. It’s better to send binary data, using an encoding which compresses small values a little (which also happens with ASCII: small integers take fewer bytes).
