4.3 development instructions
Because bluetooth of the product is pass-through function, bluetooth programming is actually to read and
write arduino serial port (Serilal)
BLE protocol stipulates that the length of each bluetooth packet should not exceed 20byte, and the data
transmission interval of each packet should be more than 150ms, otherwise it is easy to lose the packet. We
need to pay attention to two points when programming
4.4 Ble-Nano master-slave communication and Processing application
Most of the time, we use Ble Nano and Processing to complete our own ideas. The simplest solution is as
follows
