How to remove Tx_power(3bytes) in Advertising data packets? ( STM32WB55RG )
Hi I'm mattehw.When I Tested advertise setting using P-Nucleo-WB55 board, error occurred about advertise max length.so I have question about STM32WB55 BLE advertise setting.I want to use Local Name(10bytes) + 128bit UUID(18bytes) in advertising data(...
STM32WB55 Running BLE Stack not resettable using hardware reset
I have a custom board running the BLE (full) stack. The application code is written using the Zephyr RTOS. The power source is a CR2032 coin cell battery. After operating for a while (the actual times vary), some units (not all as far as I know) get ...
stm32wl55ccu6 - synchronization between m4 and m0
I started my project from scratch in CubeIde. So just select stm32wl55ccu6, choose all necessary peripherals and lorawan. Unfortunately, from scratch, this MCU can't choose only one core option(M4). To be able to use the Lorawan option, I need to IPC...
Receiving HCI_HARDWARE_ERROR_EVENT event_time_overrun, advertising never observed
My company is working on a product based on the STM32WB55, using the full BLE stack, currently v1.11.0. The error described below was also occurring on v1.10.1 previously.As far as the host application on CPU1 knows, the device is advertising success...
STMWB55: Flash write access during BLE connection
Hello,We are trying to write(erase) the flash during BLE connection.If we follow the STM32Cube_FW_WB_V1.4.0/Projects/P-NUCLEO-WB55.Nucleo/Examples/FLASH/FLASH_EraseProgramExample the BLE connection terminates immediately (timeout error code).Apparent...
What is the connection between RTCCLK and Sysclock?
I am using hw_timerserver and sequencer for BLE. I added additional tasks to the sequencer for my application. It appeared that my tasks are running much too frequently, so I looked into the clock configuration of the RTC and found that WUCLK was d...
STM32WB SRAM2A what is the size that can be used without interfering with BLE ?
I really need to use the SRAM2A that can hold data while in standby mode.But I have a hard time finding how much of the SRAM2A that I can use without meddling with BLE ? I found (STM32WB software architecture AN5289) and the mention about SBRSA But n...
STM32WB55 ScanRequest stucks in hci_cmd_resp_wait forever after couple of hours of test

STM32WB55，on our customer board, ble statck init failed, but the code work well in demo board.
In the function Ble_Hci_Gap_Gatt_Init(), it stopped at hci_cmd_resp_wait(HCI_TL_DEFAULT_TIMEOUT);And does not advertising any signal.what the problem may be with my board.Thanks.
