First of all, Bluetooth works in the frequency band of 2.4GHz, which determines that the distance cannot be too far. Common Bluetooth modules in the market are all within the line of sight of 10 meter. In addition, the power consumption of Bluetooth protocol is quite high. If it is battery powered, it is not recommended to choose, and the interference problem is not obvious. The above is determined by the nature of Bluetooth. Let's talk about feasibility first Bluetooth is a huge protocol. It is difficult to transplant if it runs directly on the single chip microcomputer plus wireless module. Now there is a serial Bluetooth transparent transmission module on the market, which is a serial communication for users and is much more convenient to develop.

Advantage is the universal advantage of wireless technology. I don't like pasting. It's handmade. I hope it will help.
