Resolved! Add Custom Service

I want to add a custom BLE service in STM32CubeMX. I saw on a website that the Add Custom Service feature could be used for this. However, I don't know the procedure for adding a service using this feature. Please tell me the steps to add a service u...

BLE Events with sequencer

Hello,I am using P-Nucleo-WB55. I have made a simple BLE server example that receives data from a client and it's working well. But whenever I add sequencer tasks, while these tasks are running, if I send any data from the client (ST BLE App), the nu...

STM32WL33 Low Power

If LPAWUR, Sigfox, and Tiny_LPM are enabled in PWR_DEEPSTOP_RTC example code, will the RTC wakeup mode and DeepStop mode work properly?

Resolved! BLE_p2pServer Example: Why adding 2 to aPeerToPeerContext.P2PNotifyServerToClientCharHdle

I would like to know why 2 is added to the P2PNotifyServerToClientCharHdle while checking for an attribute handle match in p2p_stm.c file. Later in the same function, 1 is added to P2PWriteClientToServerCharHdle. Is there an implicit assumption made ...

stm32wle5 bga package - output return loss measurement(tx mode)

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...

Resolved! STM32WB5MMG 32.774 kHz clock compensation

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...

NUCLEO-WL55JC Distance Range

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...

Powering STM32WLE5CCU6 without RF

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...

I2C and BLE on the STM32WB05

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...

Resolved! Sleep stm32wb55

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...
