Hi community,I have an application to sample the ADC and go to sleep(STOP2) mode. From the RM0434 got to know that cannot use the ADC/DMA interrupt as a wakeup source to get the ADC converted valuesSo I went with the Polling approach as shown in the ...

Hi ST Community Is it possible to use the ADC polling/DMA/IT in STOP2 mode. The application is to develop a low power platform for ADC sampling and go back to sleep. After a certain period send this data over BLE.

Hey,I'm working on custom BLE Central and Peripheral project to make connection and send some sensor data over BLE. For this I'm referring to BLE p2pServer and p2pClient along with p2pRouter example projects. I'm able to make a connection with the se...

Hello,I'm using a custom board which has STM32WB55 as the MCU. For the application, requires the MCU in sleep mode. The chosen sleep mode is STOP2. I referred the example project 'PWR_STOP2_RTC' which is available for the p-nucleo board and tried to ...

Hey!!I have a BLE application which runs on custom server profile. There are few characteristics of a given service, where the client can modify them. I need clarifications for the below questions.Is there any event generated by the BLE stack to know...

@STTwo-32 I went through the example. But I was not able to see the IOC configuration and the driver files. Instead of the approach given in the example, I used ADC Polling methodIn this approach I'm getting HAL_ERROR in the HAL_ADC_PollForConversion

Hi @STTwo-32 Thanks for sharing the table. I have couple more questions1. Any necessary steps to be taken to put ADC block in low power mode2. After waking up from STOP2 mode, any re-initialization of ADC to be done so that ADC can be used in RUN mod...

@STTwo-32, Can you suggest specific things to look out for from HW perspective?@rapoorvcan help us here w.r.t HW

@STTwo-32,The original project is being carried out on a custom WB55VGQ6 board. As per your suggestion, I ported my project changes to Nucleo board. The disconnection behavior was not observed.Also , if I there is more than one primary service, then ...
