See attached clocking setup. When I run this, BLE is unreliable. I am running STM32WB55CGU6 in server/peripheral mode. For example, sometimes on power up advertising is occurring and sometimes it does not. And if advertising does work, connecting ...

I tried HCLK1 16MHz and HCLK4 32MHz and it works great with BLE. Thank you for the information.

From ST:CPU1 can run only down to 32MHz when running BLE since network co=processor CPU2 must be always clocked at 32 MHz, this is stated in section 5 of AN5289 (https://www.compel.ru/wordpress/wp-content/uploads/2019/12/en.dm00598033.pdf). CPU1 is c...

I disabled all my ADC DMA and no change. All the problems described above still occur. Again if I run CPU1 at 32MHz everything works perfectly.

And if I cycle the power a bunch of times, sometimes advertising works. But in this case the connect from client never works (client says STM32WB is not answering connect request). However the debug output on STM32CubeIDE shows healthy operation.Wi...

Also forgot to mention that I also ran with debugger via STM32CubeIDE and I see no errors when advertising is not occurring:Wireless Firmware version 1.13.0Wireless Firmware build 5FUS version 1.2.0SHCI_SUB_EVT_CODE_READY - WIRELESS_FW_RUNNING DBGMCU...
