Hello,
I am using a STM32WB5MMG on a custom board for a BLE application. I started the project with the Client profile. The application is able to scan and receive advertisement frames. I use a MAC filter to select on peripheral and try to connect to it. As soon as I try to connect to the server with the function aci_gap_create_connection, the program enters an infinite loop inside hci_cmd_resp_wait. The response of this particular HCI command is never received.
I don't think it is related to bad parameter value such connection interval because I already faced this issue and in this case the function aci_gap_create_connection was returning an accurate error code.
RTC is on LSE, wakeup is activated, IPCC interrupts are enabled, RFWKP is on LSE.
As suggested in another post, I monitore the SR flash register and SRAM2A first register to see if CPU2 entered Hardfault but it does not seem to.
I changed a bit hci_cmd_resp_wait and hci_cmd_resp_release to provide a timeout in case no reply is ever get from CPU2:
void hci_cmd_resp_release(uint32_t flag)
{
HW_TS_Stop(timeout_ts_ID);
UTIL_SEQ_SetEvt(1 << CFG_IDLEEVT_HCI_CMD_EVT_RSP_ID);
return;
}
void hci_cmd_resp_wait(uint32_t timeout)
{
HW_TS_Start(timeout_ts_ID, MS_TO_TICKS(timeout));
UTIL_SEQ_WaitEvt(1 << CFG_IDLEEVT_HCI_CMD_EVT_RSP_ID);
return;
}
static void TimeoutHCI(void)
{
LOG_WARNING("Timeout");
/* Affichage de l'état du coeur 2 voir AN5289 rev 18 p 40 s*/
uint32_t* ptr = SRAM2A_BASE;
LOG_DEBUG("FLASH_SR CPU2 Keyword CPU2 Link Register CPU2 stack pointer");
LOG_DEBUG("0x%08lX 0x%08lX 0x%08lX 0x%08lX 0x%08lX",FLASH->SR,*ptr, ptr[1],ptr[2],ptr[3]);
hci_cmd_resp_release(0);
}
Below is a light trace ouput to show the problem:

Up.
Sorry about this but we are stuck on this for a couple of months..

Hi BBute.1,
I've just done the test on my side with a “p2pClient” on the STM32WB5MMG starting from release v1.20.0.
I don't reproduce the problem you encountered.
Would it be possible for you to share with us your project running on DK please?
BR, Joé
