I use USB dongle as BLE_p2pRouter to receive notifications from multiple P2Pservers (16bytes notificaiton). The code I wrote is as follows:When I connect to Server1, it can output normally, but when I connect to Server2, it can only output server2 no...

I made a PCB board with STM32WB5MMG, which receives the data of max30112 through external falling edge interrupt and sends it through BLE notify. However, once I add the execution task UTIL_SEQ_SetTask(1<<CFG_TASK_SPO2_EVT_ID,CFG_SCH_PRIO_0); in HAL_...

I used stm32wb55rgv6 and stm32wb5mmg in the stm32wb series for simple Bluetooth projects (using hw_timeserver to send notification data), and then used nRF Connect to receive notification data. My program and design are basically the same, but only s...

I make a board using STM32WB5MMG. The I2C and SPI communications are normal, but I find a lot of problems about BLE function.After using BLE p2p server.ioc (based on stm32wb5mmg) to generate the IDE project, the Bluetooth broadcast cannot be found an...

In the datasheet of STM32WB5MMG, BOOT0 does not need to connect pull-up resistors and pull-down resistors, just connect GND or VCC directly.In STM32WB5MM DK schematic，Do swdio and swclk need to be connected with pull-up or pull-down resistors? I wan...

I made a PCB board using STM32WB5MMG, max30112 (sensor chip) and max30001 (sensor chip). I collected the signal by triggering an interrupt on the external falling edge and sent it through BLE notify. Max30112 has an interrupt pin MAX30112_INTB_Pin (P...

The last question I asked was too redundant and didn't explain the problem well. I want to delete the previous question but can't find the delete button.

@baydı.1 Have you solved this problem? I added the UTIL_SEQ_SetTask function to HAL_GPIO_EXTI_Callback, and my program also crashed. I also tried various methods, but still no solution...Thanks and regards.

Have you solved this problem? This problem has puzzled me for a long time. I used stm32wb5mmg to make a PCBboard, and collected data and BLE notification through external interrupt (EXT0) (I used the latest library 1.17.2...)
