Hello,is it right that STM32WB55CGU6TR is already pre-loaded with FUS v1.2.0.0?
Resolved! STM32WB5MMG: What are the characteristics of the LSE crystal?
Hi everybody, I have been looking for the charateristics (like ppm/temperature dependency) of the LSE crystal included in the STM32WBMMG, but I have not been able to find on its datasheet.Is there another document I am missing where the information a...
Resolved! Custom made ble characteristic updater don't work
Hello everyone!I just started learning how to use the STM32WB-Chips on the Nucleo-WB55RG and followed this tutorial: https://www.youtube.com/watch?v=Zgw3wRpGSRQ&list=PLnMKNibPkDnG9JRe2fbOOpVpWY7E4WbJ-&index=17After that I tried to make a function (fo...
Resolved! STM32WB5MM-DK power consumption test with x-nucleo-lpm01a
How do I connect x-nucleo-lpm01a with STM32WB5MM-DK to test power?I am using the RF module from STM32WB5MM-DK and not the one from P-NUCLEO-WB55.I know that there is a video for P-NUCLEO-WB55. Is there a video/guide for STM32WB5MM-DK as well?
How to use HAL DMA to generate PWM on P-NUCLEO-WB?
I am trying to generate PWM by using DMA with HAL library: uint16_t buffer[1] = {1500}; ... Status = HAL_TIM_PWM_Start_DMA(&htim2, TIM_CHANNEL_1, (uint32_t *)buffer, 1);however nothing happens. I am able to generate PWM without DMA: TIM2->CCR1 = 5...
L2CAP (COC) sends one packet per connection interval
Hello,Apparently COC channel can send no more than one packet (MPS) per connection interval.Trying to end more will result in BLE_STATUS_INSUFFICIENT_RESOURCESThis seems to be a bug since GATT (on same exact setup) can do at least 2, resulting in muc...
Reconfigure clocks on STM32WB55 BleHeartFreeRTOS
Hello,Curious regarding clock reconfiguration and MX_XXX_Init on wake up with STM32WB family.I see that in the example BLE_HeartRateRTOS the clock configuration on wake up is blank!Why is that? Doesn't in necessary to do the clock init again? this i...
