When the STM32WB06 is in the automatic connection enabled state, it is unable to enter the low power mode and the automatic connection fails aft
Hi, I'm having some issues with the STM32WB06 when trying to achieve low power consumption. I hope someone can help me solve these problems.Issue 1: After initializing the Bluetooth protocol stack and enabling automatic connection establishment, it c...
ADC giving value of 4095 on all configured channel
Hello Community,I am working on a custom board using the STM32 MCU (STM32WLE5JCI6). I am configuring the ADC with two channels:PB1 → ADC_IN5PB3 → ADC_IN2I performed the following test cases and observed unexpected ADC behavior.Test Case 1Applied VDD+...
Advice on antenna tuning ?
I am currently working to redesign one of our products to include Bluetooth communication for remote control. For this, I am targetting the STM32WBA23.Given that the PCB is mounted inside a solid, cast-aluminium housing, I will need to put the antenn...
STM32WB: HCI_HARDWARE_ERROR_EVENT (0x02 – BlueCore Time Overrun) Observed on Some Devices
Hi everyone,I am encountering a HCI_HARDWARE_ERROR_EVENT with code 0x02 (BlueCore time overrun error) on STM32WB devices.Key observations:Issue is observed only on some units, while others operate normallyAll devices use the same firmware, BLE stack,...

Hardware: STM32 NUCLEO-WB15CC (STM32WB15CCUX) RTOS: FreeRTOS BLE stack: STM32WB WPAN / BLE via CPU2 (M0+) Hi, When writing a small configuration block (~48 bytes) to the internal Flash from CPU1 (M4 FreeRTOS task), the BLE connection drops immedi...
RTC in STM32WBA65 after reboot
I have an STM32WBA data logging project loosely based on the BLE heart rate project. I sync the RTC via either a BLE message, or NTP from a serial modem. All good; works well and the RTC timestamp ticks along whilst the code is in stop2 sleep. The de...
