Hello! We are a bit stumped here. We have a product that we are testing at 65C and it seems that the bluetooth connection keeps dropping at this temperature (Connection timeouts). We are running from a 32K LSE and 32M HSE crystals. All our parts ...

I have been trying to implement a HCI only interface (LL only set) and pass commands to my board (STM32WB55 Nucleo board - BTStack is the bluetooth stack). Everything works except for the following sequence-> Connect, pair and bond with Just works (...

I am trying to implement an HCI interface and the stack is reporting almost nothing supported in the HCI_READ_LOCAL_SUPPORTED_FEATURES command. Why is this? Is there a way to enable the features? I am using stack v1.16. I have tried multiple variatio...

So, when I first connect to my USB implementation and send the first 3 bytes to the command/control interface I get 3 zeros. It is not what I sent and interestingly enough I do get the bytes I sent the first time on the next 3 bytes. I have no idea...

Ive seen this issue in various different forms over the last 2 years and it seems like CPU2 is corrupting the TL_RefTable structure while configuring advertising. We are using v1.15.0 of the stack on a STM32WB55. This happens every few hours in the f...

Apologies, that was a typo. We are using 32M for HSE.

Did you ever find the answer to this? I am also trying to use hci_le_set_extended_scan_enable. It tells me that the HCI parameters are invalid, but they arent....

Well, the command itself is supported, unfortunately it list most features as not supported, even though I know that they are supported...

Sorry, I posted a response just as you sent another reply. My unfamiliarity with USB led me to assume that data was being transferred in the Setup function, but apparently its not available until the EP0_RxReady interrupt fires. I will shift things...

Never mind, I think I found my problem. I was not waiting for EP0_RxReady. I assumed the data was transferred when I called USBD_CtlPrepareRx.

STM32WB55 BLE connection issues at higher temperature.

HCI bluetooth can pair initially, but re-starting encryption always ends with 0x3D MIC failure

HCI_READ_LOCAL_SUPPORTED_FEATURES shows nothing supported.

Strange USB behavior - getting 3 bytes of data I didn't send.
