Latest task-Wireless Communication Protocol

This photo has nothing to do with the past two days. This is the domino mahjong that was played at the bank ditch at the end of August. It was a pity that I did not succeed once after half a day. The two days have never been so leisurely. Recently, I was busy working on a wireless communication project. It was in another competition. I have been engaged in some Bluetooth development before, which is very helpful but far from enough. The development of Bluetooth is an application of wireless communication protocols. in this competition, we need to design a wireless communication protocol, so that we know that it is so difficult to design a simple protocol.
After a period of wireless communication, it is like discovering another place. In fact, in addition to Bluetooth wireless applications, there are many other wireless types, which are also very convenient to use and have high performance. But it has not become an international standard, so applications have limitations.
This project uses the nrf9e5 system-level communication chip (I don't know what it is called "system-level", but there is no concept yet, so I can say that), which is quite powerful, M communication in an open site, with a speed of about 80 K, and easy to control. Built-in 51 compatible single-chip microcomputer. Supports 170 frequency hops. It is really a good thing to contact and write communication protocols.
