If ST Micro uses custom HCI commands to create services then it means they are running both Host and Controller. For a platform-neutral Host that can work with any standard HCI device (including Zephy

Hi Carles, I should be hitting Group Reply so the thread is captured. Apologies :) it seems ST Micro (for their BlueNRG chipsets) uses custom HCI Vendor commands (ogf 0x3F) to create services so they

Hi there, I am unclear as to what you are asking exactly, but I’ll give it a go. If your question is whether porting Zephyr code to another RTOS is easy, the answer is: generally it is not, because ev

Instead of adding k_usleep(30), I changed the SPI clock from 210kHz to 406kHz for STM32F769. Then, the problems of A and B are gone. Still I have the problem of C. I receive 0x07 instead of 0x01. From

From what I checked: - A. 74 clocks stop with a change in CS without sufficient delay - B. CMD0 (0x40 0x00 0x00 0x00 0x00 0x94) fails to send 0x40... (instead send 0x20...) - C. CMD0 fails to receive

Thanks for the answer. You are right, the problem was solved implementing the fatfs_unmount function that you said. I made some tests and everything is ok. On the weekend I will create a PR.

Lucas, You're right, the unmount operation isn't implemented in the FAT fs_file_system_t struct. It should be possible to implement it easily, though. Something along the lines of: static int fatfs_un
