Hi
I have an app working perfectly on a Nucleo board and the MB2032 for the STM32WB05. Just the standrd default setup there.
I have built my own board now following the application notes and the guides. It all starts ok but as soon as it gets to the aci command to start advertising then it restarts. I have reduced down to -54dB and it still fails. If i set advertising to DISABLE in that call then it will starts up perfectly.
This is when running of a PSU and a CR2032 battery.
Anyone seen this? Did I forget some simple setting when transitioning from the Nucleo to my own board (using onboard STM32 SMPS)
Thanks

Additional note, the board is drawing 7mA during the boot and when it is running (no advertising)
I've triple checked all of the SMPS components and it all looks good per datasheets and reference designs.
I run in SMPS ON mode
