Updating advertisement packet after waking up from standby mode (WB15CC)
Hi,My application (WB15CC) stays most of the time in standby mode transmitting the advertainment packet. After a couple of minutes, the advertainment packet must be updated. When I try to update the packet after waking up from the standby mode, the f...
Resolved! STM32WL55 no rf
Good dayI am using the STM32WL55 chip for a project. I did preliminary tests using the NUCLEO-WL55JC2 Development board.I created a custom PCB following the design of the Development board.When I program the custom board with the same firmware that w...
STM32WB55: C2 randomly enters spin loop
I find that when entering deep sleep/range 2 using aci_gap_set_non_discoverable(), C2 would not reliably enter the ultra low (~4uA) power consumption mode, current would jump to ~5mA. I am using stack 1.18 and even 1.19. a) Calling aci_gap_set_non_...
Resolved! SPI: changing CPOL between transmissions
I have 2 devices on my SPI bus that need different CPOL settings. both use CPHA = 0 and the SPI peripheral is configured to use Motorola frame format.Communication works with both devices if their respective CPOL setting is set in CubeMX (and thus fi...

Resolved! Using SHCI_C2_BLE_INIT_OPTIONS_REDUC_GATTDB_NVM to increase bonding list size
Wondering what is the cost of using SHCI_C2_BLE_INIT_OPTIONS_REDUC_GATTDB_NVM overSHCI_C2_BLE_INIT_OPTIONS_FULL_GATTDB_NVM ? The first one can gets me 33% increase in bonding list size but I could not find what does it prevent me from using?
