Hello. Thanks again for all your appropriate assistance.I would like to ask a question about the implementation details of BLE_Hid in STM32CubeWB.> Is the data written by aci_hal_write_config_data saved in NVM area?(Is that implementation already in ...

Hello, I am developing a BLE HID device using the STM32WB55.I am generating random static addresses using a program implemented in the STM32CubeWB. This is used to identify multiple peripherals with the same functionality. #else /* Get RNG semaphor...

Hello. I am developing a BLE HID device using the STM32CubeWB MCU Firmware Package, but when I try pairing => disconnect => pairing, pairing fails. I have an implementation like this, is there a problem?We have the following data in adv_data, whic...

Hello @Imen.D Thanks for the reply.I now understand how aci_hal_write_config_data works. Thanks.So am I correct in my understanding that the aci_hal_read_config_data function, in contrast, is used to access data stored in NVM?If so, do I need to read...

Hello. @TDK Thank you for your reply.Thanks to you I have a better understanding of UID.This time, however, I would like to add a process to change the random static address when a new connection is initiated after this (pressing the pairing button a...

Hello. @STTwo-32 Thanks for the reply. I understand now.Is there a problem with generating a 16 byte array for IRK when powering up in RNG, etc.? (Would the same process be required for LTKs?) For example, as shown below↓↓ CreateRandomNumbers(a_BLE...

The sample I am using is BLE_HID from STM32CubeWB./*** * Static random address * The two upper bits shall be set to 1 * The lowest 32bits is read from the UDN to differentiate between devices * The RNG may be used to provide a random number on each p...
