Hi,
I have an STM32WB board that is working as a central device. I have several peripheral devices, each with an advertising interval of 10 seconds.
As a result, connecting to the devices can take quite some time. Is it possible to scan and receive advertising packets while attempting to connect to a peripheral?
When I try to use the command aci_gap_start_general_discovery_proc after executing aci_gap_create_connection, I receive the error 0x0C.
I also tried using the background scan feature, which can be enabled with aci_hal_write_config_data() (offset parameter 0xC1). However, according to PM0271, section 5.2.1, I'm not entirely sure if this use case aligns with my scenario: "As explained in the previous chapter, in a multi-role scenario, the STM32WB device has the opportunity to advertise, scan, and be connected at the same time with different remote devices."
I don't have a multi-role scenario, so I don't think this feature is appropriate.
If anyone has experience with scanning and connecting simultaneously, could you please share some information?
Thank you!
Best Regards,
Daniel
