How can I make BLE work on STWINKT1?

[KaisBo7]

Hi,

I am trying to use the BLE (SPBTLE-1S chip) on my STEVAL-STWINKT1 board. The idea was to use a project example from X-Cube-BLE2 with the following configuration :

HCI_TL : Basic
HCI_TL_Interface : UserBoard
Application : SampleApp

I used the SPI2 to communicate with SPBTLE-1S.

However, I can't communicate with the BLE, the void MX_BlueNRG_MS_Init(void) fails. The function tBleStatus aci_hal_read_config_data(uint8_t offset, uint16_t data_len, uint8_t *data_len_out_p, uint8_t *data) returns BLE_STATUS_TIMEOUT.

Maybe an issue with the clock or/and the spi configurations? Or something else?

I would really appreciate your help.

Thanks.

Hello @KaisBo7 

Have you already checked the STSW-STWINKT01 package? We are providing an already ready-to-use SampleApp example that streams some sensor data and controls a led on the board.

Hello @SimonePradolini,

Thank you for your prompt response.

I have indeed tried the STSW-STWINKT01 package, and while it is helpful, my current objective is to utilize the X-Cube-BLE2 middleware for configuring the BLE module. I am particularly interested in setting up a custom BLE configuration using this middleware to better align with my project's requirements.

Could you provide any guidance or suggestions on troubleshooting the communication issue I am experiencing with the SPBTLE-1S chip when using the X-Cube-BLE2 middleware? Any insights into potential clock or SPI configuration issues that might be causing the BLE_STATUS_TIMEOUT error would be greatly appreciated.

Thank you for your assistance.

Best regards,

Kais

Hello @KaisBo7 

STSW-STWINKT01 includes the same middleware used in X-CUBE-BLE2. It is older than X-CUBE-BLE2, so it uses an older version of the middleware, but it works in the very same way.

Let me give you a couple of hints, I wish could help you solving your issue.

Can you update the BLE middleware in STSW-STWINKT01? You should copy/paste the one from X-CUBE-BLE2. If the STSW example still works, it means that both SPI and BLE configuration in STSW are still valid. So, you can try to use them in your X-CUBE-BLE2 based example.

Best regards
