I made a Demo using STM32WB5MMG to communicate with USB dongle or phone （BLE notification）,AND I collect data from the MAX30001 (two interrupt pins PC10 and PC11, SPI1 communication) and the MAX30112 chip (interrupt pin PD0, I2C3 communication) by tr...

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...

Is there any follow-up please? Or is there anything else that needs to be added to this question?

Just a red led.Mainly used to indicate some functions, of course this part can be turned off.

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...

Re: BLE (UTIL_SEQ_SetTask) and EXTI conflict？

Difference between EXTI0 and EXTI15_10 lies in interrupt callback function calling Ble notify task？
