Hello, i am trying to reproduce this demonstration https://www.youtube.com/watch?v=7IVs-nuoXj8&t=439s on a custom WB55 board (WB55CGU6). In the video, the advertising consumes about 10 mA. In my case, it is close to 20 mA. I though changing the CF...

Hello, I am trying to achieve high throughput on a custom board. I partially replicated BLE_Throughput example for an initial testing.I am receiving the BLE data in MATLAB. In CubeMX, I use a custom ble template. I am trying send a payload 1000x time...

Hello, I am trying to read battery voltage within a task called by sequencer on STM32WB55CEU.I am following this post: https://community.st.com/t5/stm32-mcus/how-to-use-the-stm32-adc-s-internal-reference-voltage/ta-p/621425I verified that I can measu...

Hello,I am using STM32WB55CEU6, when using EXTI callback with BLE and LPM enabled, the MCU never enters the desired STOP2 power mode. The callback triggers every 20 seconds and is used to set a task by calling UTIL_SEQ_SetTask(...).When a virtual ti...

Hello, I am developing a Dog Activity Recognition app with CubeAI on STM32WB55 usign AI Core 9.0.0. So far, I have been following https://wiki.st.com/stm32mcu/wiki/AI:How_to_perform_motion_sensing_on_STM32L4_IoTnode . I am using the same sensor and O...

Thanks, that´s a really helpful example you provided.

Thanks, but is there any info how to actually set the TX power level? In CubeMX, one can set the CFG_TX_POWER macro desired level, but the other two macros remain 0. Are they not relevant? It is quite confusing.

transfer_count was declared as uint8_t, works correctly as uint32_t. Silly mistake.

The sequence of sensor input data for model input batch (segment) was different between Colab and Cube, which was not obvious at first. After correcting the input batch format in Colab, now I get same results in Colab and Cube. You can perform "Valid...

Thanks for replying,the error was that the dataset was segmented in different way in Python and in CubeIDE (which was my mystake), so the AI input was after all different in Colab and Cube. That is why it always predicted the same activity. If this w...
