SPBTLE-RF + FreeRTOS

Hallo,

I'm a student and I would like to design a product with the SPBTLE-RF module.

I have a Nucleo64-401RE and the X-NUCLEO-IDB05A1 board.

Using CubeMX I can successfully recreate the SensorDemo application.

For my own design I started gethering some code lines from multiple demo applications and it seems that I am kind of successful because my PC with a Bluetooth dongle can find and connect to the module with the chosen password. Hoever it does not work with my smartphone.

Nevertheless I am missing quite a lot of understanding about the functionality of the Bluetooth HCI.

What I would like to do is to connect to the module via a smartphone to transmit short packages of data. Also the firmware of the host microcontroller should use the FreeRTOS given through CubeMX. I tried to generate the SensorDemo application with FreeRTOS enabled but then it does not work anymore.

So my questions are:

  1. Is it possible to use FreeRTOS in combination with the BLE additional software?
  2. Where can I get some detailed guides on how to create custom applications with BLE?

A few months ago I already asked something similar in this community and got no response.

Even If you don't know a detailed answer, any hint on how I could continue would be great!

Thank you!

Please firstly make sure the HCI (SPI) interface works properly.

Please refer to PM0237 - BlueNRG, BlueNRG-MS stacks programming guidelines

Hello @Winfred LU​ I have such as problem when I added freeRTOS to BLE. I checked SPI and seems that all right with him. In Keil I get errors:
