There was nothing in my discovery, nor in my actual case. Because I don't have a fun Bluetooth low-power device on hand yet. The whole story is based on what Mike Ryan has published over the years.0x01 BLEWhat is

Bluetooth Low-Power BLE: Controls GPIO to light LEDs and blegpio This section describes the simplest and most basic things. The ios operation of the CC2540 uses the PORT as the GPIO. If you don't talk much about it, let's look at it. 1. Hardware Circuit The most simple hardware circuit is to use a GPIO to control the LED light. Since GPIO is used as the output, t
