How I use the BlueBRG as HCI-UART, on Bluez 5.55 stack as BT LE LR Dongle, command on btmgmt "find -l" thoes return nothing... ?

Solved:// wait for TIM6 (HAL timebase) complite current IT (if pending) while (0 != TIM6->SR) { } // clear WU flag __HAL_PWR_CLEAR_FLAG(PWR_FLAG_WU); // Go to stop mode HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI);__HAL_PWR_CLEA...

At the moment it is known:1. WKUP IT works in normal mode (IT priority 0)2. WKUP IT works in SLEEP mode (IT priority 0)3. WKUP IT NOT works in STOP mode (IT priority 0)4. Try to enter in stanby mode leads to immediate reboot...No need toggle pin, ter...

Change wake-up priority from 5 to 0 and it's works without STOP mode. In stop mode wake-up IT not works...

In moment of power of the board I receive the WKAP interrupt... Ony in turn power off moment...

Without STOP WKAP still not works. REGs cheked all OK :(, ideas?

STM32L151CBT6A MCU, Enter stop mode have biggest power consumption - above 960uA, but datasheet is ~2..10uA ? And MCU not wake up from STOP by RTC WKUP

Have: STM32L151C8xxA Get VREFINT trouble (VREFINT voltage drifts depended on external power supply), how to get REAL input voltage?

Why BlueNRG LP not working as HCI-UART, DTM example not works! Not scanning from Bluez 5.53
