How to create a BLE application step by step using STM32WB55 P-Nucleo

[kcire L.]

Hello,

I am using the STM32WB55 Nucleo board and have gone through a few of the example applications. I would now like to create my own BLE application similar to the heart rate monitor.

I really am not sure how to start and was hoping for a decent tutorial or video on the flow of adding BLE functionality.

If anyone has any tips I would really appreciate it.

Thanks

Hello @kcire L.​ ,

Have a look at the attached getting started and workshop for BLE.

Also, refer to the following resources :

• AN5289 Application note "Building wireless applications with STM32WB Series microcontrollers".
• Video: STM32WB Getting Started Series: Part 5, CubeWB Heart Rate Monitor to start developing your application.

I hope these resources are helpful for you.

Thank you for your response. I've watched the video you suggested. I'm also looking at the BLE Heart Rate Monitor example and trying to go through the steps in AN5289.

I cannot find even the first call aci_hal_write_config_data() to configure the BLE device public address. I assume this is used, but I am not sure where this code resides? Again, I am trying to create a BLE application from scratch.

Thank you again

Hi @kcire L.​ ,

The aci_hal_write_config_data command writes a value to a low level configure data structure, and it is useful to set up directly some low level parameters for the system in the runtime.

Please refer to the "4.8.1 Aci_Hal_Write_Config_Data" section in the UM1865, to have more details about the configuration of this command.
