I was testing the STM32WB5MMG on the new U585 IOTA discovery kit and I'm facing some issues.
I generated a project using STM32CubeIde with the MXEditor. After enabling all the default peripherals and changing the example config of BLE, some points are noted:
- The RTC Backup domain registers are protected, you have to call HAL_PWR_EnableBkUpAccess(); prior to executing HAL_RTC_Init, otherwise it will fail with a timeout.
- IPCC interrupts are not enabled automatically when enabling the RF + STM32_WPAN, so you will manually have to go to the NVIC controller and enable them.
Now after fixing this, atleast I could get the code running and the advertisers showing in.
In whireshark I can see that:
- STM32WB5MMG is sending ADV_IND
- Mobile phone is sending SCAN_REQ
- STM32WB5MMG is responding with SCAN_RES
- Mobile phone sends CONNECT_IND
- The STM32WB5MMG is not establishing the connection.
Is this a know behaviour? Am I missing something? Like and API call to process the connection request? I'm using a custom template, but the HEARTRATE SENSOR example exhibits the same behaviour.
Kind regards
