Examples
For the Pico-BLE module, we provide an serial example. Hereby we take C codes to explain the function.
Hardware Interface
BLE.c
The Bluetooth module initialization function mainly judges whether the Bluetooth module is successfully connected to the mobile phone, whether the notify function is enabled, querying the baud rate of the Bluetooth module, judges whether it is in low power mode, name, address, and modifying the name of the module.
void BLE_Init()
Execute and process BLE commands.
uint8_t Cmd_Process(uint8_t *data) data: the address of the command pointer to send
Transparent transmission receiving function, what data the mobile phone sends to the module, the module receives and returns the same data with this function.
void UART_RX() Query receive void UART_RX_IRQ() Interrupt receive
Parameter Modification
BLE.h
#define UART_ID uart0 Pico serial port selection #define BAUD_RATE 115200 Serial port baud rate selection #define DATA_BITS 8 Serial port data bits #define STOP_BITS 1 Serial port data stop bits #define PARITY UART_PARITY_NONE Whether the serial port performs parity check #define UART_TX_PIN 0 Pico serial port TX pin selection #define UART_RX_PIN 1 Pico serial port RX pin selection #define BLE_MODE_PIN 15 Bluetooth module status detection pin
Module Command
CMD.h
For specific use, please refer to the user manual.
Demonstration
Mobile Phone APP Demo
Connect the Pico and Pico-BLE:
Open the Python demo and run:
Open the software on the smartphone. (This is just a demo, you can download any Bluetooth APP from the app store.)
Click to pair:
Click on Pairing and the following will appear on the computer and the phone:
Enter the data on your cell phone and click send (your computer will show you the screen where you sent it):
PS: Apps using the BLE protocol on the mobile side need to open the notify interface.
