Resolved! How to wake up CPU1 with RF subsystem?
Hi everybody, how can the CPU1 of module STM32WB5MMG be waken up by the RF subsystem?The idea in mind is to use the module as a BLE Server, have the CPU2 perform advertising while the CPU1 is in STOP2 mode. According to the reference manual RM0434, t...
Resolved! STM32WBMMG: Code between USER DEFINED CODE comments for descriptors gets deleted with updates!
Hi all, I think this is a bug of CubeMX. Everytime the .ioc gets updated for the project, the code written for the descriptor characteristics get deleted in the SVCCTL_InitCustomSvc() of the autogenerated custom_stm.c file.I don't know if this issue ...
What did CAP_Init do? Why does it return BLE_STATUS_OUT_OF_MEMORY
HI， I am developing my ble audio headphone with STM32WBA55G-DK1.But when i called the CAP_Init function which provided by ST with binary library, the CAP_Init function return BLE_STATUS_OUT_OF_MEMORY. I compared with the STM32WBA55G-DK1 demo applic...
Resolved! How to setup un-used pins of STM32WLE5JCI6 for optimal EMC and current drain performance
For best EMC immunity and minimum cell current (need months of cell life), how to setup un-used pins of STM32WLE5JCI6? The chip in a module with metal screen box. Pins are 'broken out' to edge of module with pcb trace of a few mm.a. Should we progr...
