Hardware and Software environment
- This example runs on STM32WBA55xx devices. Connect the Nucleo Board to your PC with a USB cable type A to mini-B to ST-LINK connector (USB_STLINK).
How to use it?
In order to make the program work, you must do the following:
- Open IAR toolchain
- Rebuild all files and flash the board with the executable file.
Two STM32WBA nucleo boards are used. One board is configured as central thanks to BLE_SerialCom_Central and the other as peripheral thanks to BLE_SerialCom_Peripheral. The central board supports the Data transfer by sending L2CAP data through a COC link.
No service is added.
After BLE link is established, a Connection Oriented Channel (COC) is established (full stack is necessary for COC) Data are exchanged through the COC link.
Open a VT100 terminal on Central and Peripheral side (ST Link Com Port, @115200 bauds). This application has to be used in front of BLE_SerialCom_Peripheral.
At reset application initialization is done.
- The peripheral device starts advertising.
- Push B1 on central: the central device scans and automatically connects to the peripheral (use of CFG_DEV_ID_BLE_COC).
- After BLE connection:
the client establishes a COC channel.
- When link is ready: display “CONNECTION READY”
- Configure the terminal with settings local echo.
When Append LF is configured, enter data using keyboard, check that data are correctly received on peer device.
There are two different modes to send messages from an STM32WBA: “Send button” or “Real time”. After reset, “Real time” mode is selected. In terminal, when you type the message: - In “Send button” mode, data are sent when LF is sent. - In “Real time” mode, each character is immediately sent.
On server side when connected:
- B1 changes “send data mode”
- B2 sends slave security request
On server side when idle:
- B1 changes “send data mode”
- B2 clear database
On client side when connected:
- B1 changes “send data mode”
- B2 sends pairing request
- B3 changes connection interval update
On client side when idle:
