Hello everyone, I hope all is well. I'm trying to learn how to use the STM32 by creating a personal project, and I'm stuck on the Bluetooth part. I've watched videos, read documentation, etc., and I can't see where I'm going wrong. I've been making mistakes for just over a month now. Sorry for the long post.

Bonjour à tous, j'espère que tout va bien. J'essaie d'apprendre à utiliser le STM32 en créant un projet personnel, et je suis bloqué sur la partie Bluetooth. J'ai regardé des vidéos, lu de la documentation, etc., et je ne vois pas où je me trompe. Cela fait un peu plus d'un mois que je suis en train de faire des erreurs. Désolé pour ce long message.

I have the pins correctly matched according to the document ‘Getting started with the STMicroelectronics X-CUBE-BLE2 software package for STM32CubeMX’. They are as follows:

PB7/6 = USART1_TX/RX respectively

PC12/11/10 = SPI3_SCK/MISO/MOSI respectively

As I said, I've been working on this for a month and sometimes I get a different error, but I'm back to the original error. This is when initialising MX_BlueNRG_MS_Init();

In hci_tl.c, at this party

J'ai les broches correctement appariées selon le document « Démarrage avec le progiciel STMicroelectronics X-CUBE-BLE2 pour STM32CubeMX ». Elles sont les suivantes :

PB7/6 = USART1_TX/RX respectivement

PC12/11/10 = SPI3_SCK/MISO/MOSI respectivement

Comme je l'ai dit, cela fait un mois que je travaille là-dessus et parfois, je rencontre une erreur différente, mais je suis revenu à l'erreur initiale. C'est lors de l'initialisation de MX_BlueNRG_MS_Init();

Dans hci_tl.c, à cette fête
