Hi,
I developed PCB with STM32WB5MMGH6TR. I have code which I used previously with STM32WB55RG (on Nucleo board). I adapted it for STM32WB5MMGH6TR and it works (GPIO, SPI, I2C) except the BLE part. So I took STM's BLE_HearRate example for STM32WB5MM-DK, but it does not work as well. I mean that the STM BLE Toolbox app does not discover the STM32WB5MMGH6TR.
I don't know if the issue is with the FW/MCU configuration or is it with incorrect design of the PCB. Any hints what might be wrong? suggestions how to debug? I can share the PCB design.
