Hi, Colleagues I created my PCB board with stm32wb55cgu6 for transmitting data via BLE and want to check this design. Maybe who has a .hex file for BLE transmission to the mobile phone, I need only detect in my phone whether this board a visible or not

[IRakh.1]

I didn't use external oscillator for frequency, all clock is set from the microcontroller internally

I mean BLE need crystal for ... And examples is in firmware folder repository ...

Configuring STM32WB for Bluetooth LE without an LSE crystal

thank you for share it.

Looks like can work with HSE, but I still need an example

The same examples exist as when you designed it, perhaps review what's actually available in CubeWB, and if any of that gets close to what you want, or can be adapted.
