Hi , I am trying to measure the output return loss ( in tx mode) of my board rf chain which include the stm32wle5.if i understnad correctly - in order to do that i need to put the STM32WLE5 in TX MODE which means its PA should be powered up and read...
Hi all, We are using a STM32WB5MMG uC in one of our products and we just happened to see in its datasheet that the secondary crystal frequency is 32.774 kHz, instead of the common 32.768 kHz, is that right?We are using the internal RTC clocked by the...
Hello ST Expert ,I'm using the NUCLEO-WL55JC1 for my project as Gateway and End-device.I have one Gateway and 4 end device ( based on the same baord ) , i don't made any hardware change , and I'm using the SW delivered by STMicroelectronics.I have an...
Hi,I’m designing a PCB with the STM32WLE5CCU6. I don’t plan to use the integrated RF (LoRa) section, but the MCU choice is fixed.I couldn’t find clear guidance in the datasheet on how to power the device when the RF block is unused. I’d like to optim...
Hi, allI'm developing a BLE device using the STM32WB05 that supports I2C and BLE connections.I successfully established an I2C connection using I2C_SCL(PB6) and I2C_SDA(PB7).However, PB7 is used for RADIO_RF_ACTIVITY on BLE, causing a conflict betwee...
Hi, I'm working with an STM32WB55cgu6. I'm having trouble with power consumption in sleep mode, which is around 100μA or more. I replaced the chip and it dropped to 35-50μA, but on newer boards it's around 30μA. I'd like to know if there's any config...
Hello :) I am developing an application using a pair of NUCLEO-WL33CC1. I am testing the LPAWUR, using the LPAWUR_WakeupRadio_Rx and MRSUBG_WakeupRadio_Tx examples as a starting point. The examples work fine, but the range is very short, only about 0...
Hi, I want to make a simple application with an STM32WB5MMG that exposes a characteristic which I can read. I created the service and the characteristic, and I enabled the CHAR_PROP_READ property. In custom_app.c, I then use Custom_STM_App_Update_Cha...
On the STM32WL33 chip, is it possible to switch between LPAWUR Wake-up Radio Rx mode and PWR DeepStop RTC mode in the same code?
DescriptionI am developing a system with STM32WB5MMG module.A pushbutton is connected to PA0 and is used to control the system power state:During runtime, PA0 works as an EXTI interrupt to request shutdown.In shutdown mode, PA0 should act as the wake...
