Resolved! How do I connect the ground of a high-speed external crystal oscillator in the STM32WB55?
I've looked at the reference design in the application note AN5615 page 13. This micro controller has integrated load capacitors for the high speed external oscillator. In the bottom right package, on the 32Mhz oscillator there is a symbol leading to...
Updating Network Stack through SWD on STM32WB55 Leads to Errors
I attempted to update the network stack through SWD on a few STM32WB55 nucleo boards, dongles, and custom PCBs. The results were similar in all cases. When attempting to query the processor to see if the FUS is out-of-date (it should be since these w...
Bootloader STM_OTA update firmware and access to BLE characteristics via BLE and python script or other CLI
Hi all,I using Nucleo STM32WB55 and bootloader from STM (STM_OTA). For update firmware I using for now STM32CubeMonitor-RF and stm32WB USB DONGLE (which is part of nucleo kit). Now I would like to do this in other way - other tools, CLI, scripts...Is...
Resolved! HSEM HAL strange behavior
Hi,I'm playing around HSEM module and i noticed strange behavior. Why calling:HAL_HSEM_FastTake(HSEM_ID_0);orHAL_HSEM_Take(HSEM_ID_0, 0);lock all semaphores at once instead of just locking single semaphore specified by a macro using 0 as processid?Th...
BUG report: Code generation on STM32CubeIDE for STM32WB with RTC in LL
Hello,when specifying "use low level driver" for RTC in "Project Manager->Advanced Settings" of ioc editor in STM32CubeIDE, the generated code of the STM32_WPAN does not compile anymore, since it needs the drivers in "HAL version". It must also compi...
Is it possible to implement MLPF-WB55-01E3 with STM32WB55RGV6 on 4-layer PCB?
We are building a custom 4-layer PCB with STM32WB55RGV6 and would like to know if we can use MLPF-WB55-01E3 instead of discrete components. If yes, what is the PCB stack-up?Please let us know if this is feasible. Thanks in advance.regards,Kishan
Resolved! Hello, I am developing a device using stm32wl and I have a few questions.
The power supply diagram shows the vssa pin of the chip, but it is not specified in the Pinout. It is also not clear the vddpa designation(= VDDRF1V5 or VDDSMPS) and why it is not connected anywhere. I also didn't find any information about vssrf. do...
STM32WB55 Low Power Mode wakeup using BLE stack
Hi,I can enter STOP Mode 2 while not using the ST Sequence (UTIL_SEQ). I disable interruptions, clear the pending ones and just let the RTC to wake me up.HAL_RTCEx_SetWakeUpTimer_IT(&hrtc, 0xFFFF, RTC_WAKEUPCLOCK_RTCCLK_DIV8); HAL_PWR_EnterSTOPMode(P...
