Resolved! Using RTC_WAKEUPCLOCK_CK_SPRE_16BITS as wakeuptimer
Good Day.I want to put my stm32wb device to sleep standby mode. and wakeup using RTC after specific time.I am following the PWR_STANDBY_RTC example which works.I would like to sleep for up to 12 hours and would like to use RTC_WAKEUPCLOCK_CK_SPRE_16...
Rx timeout issue
Dear Support,I'm using the SX1272 in lora mode in my application. I have both products that communicates together. They are configured in Rx single with a symbol timeout equal to 1000. When no communication the rxtimeout is about 1023ms. But when the...
Resolved! Impossible to get USB device and sequencer working together
Hello ST Community,Let's start with my problem:I have a STM32WB55CG chip that I want to get working in BLE. I also want it to have an USB CDC interface.I created a project on cubeMX, added my external oscillator (32MHz), activated the USB device unde...
Resolved! Problems using USB mass storage middleware with BLE stack on STM32WB55?
I'm developing an application which uses both USB mass storage and BLE. I've started by building two separate applications using STM32CubeMX:A USB mass storage application communicating with a microSD card over SPI1A BLE P2P serverBoth of these work ...
Resolved! Is there a simple way to turn BLE off and on?
I would like to be able to turn BLE off (e.g. with a timer) even if it is currently connected. I know I can stop it advertising, but this doesn't seem to kill the connection. Basically, after a timeout, I would like the BEL to shutdown and stop using...
Problem with HAL_Delay while using PWM+DMA in STM32WB55
Hello! I am using PWM to generate 1.25 ms period pulse to trigger a LED strip light . In main.c , properly in while(1) when I called HAL_TIM_PWM_Start_DMA followed by HAL_Delay the program got stuck in uint32_t tickstart = HAL_GetTick(); . When I run...
SW4STM32 fails to debug with ST-LINK/V3-MODS while it is controlled via the C-Api
I have a custom test/debug fixture for a custom board. It is based on the ST-LINK/V3-MODS board to programm the target MCU (STM32WB55).The other interfaces (GPIO, I2C) are used to control functions like power supply to the target etc.When I try to de...
Can the STM32WB55 OTA handle encrypted user applications?
As far as I understand, the OTA example provided (BLE_Ota) supports either flashing the user application directly or handing the processing over to CPU2 for decryption of the Wireless firmware (which comes as an encrypted and signed package).Is it po...
