NIST Special Publication 800-121(https://tsapps.nist.gov/publication/get_pdf.cfm?pub_id=934038)recommends using BLE Security Mode 1 Level 4 (page v) which calls forElliptic Curve Diffie-Hellman encryption. Does the latest STM32 BLE stack for the STM3...

The ADC counts returned by the internal temperature sensor appear to depend on the sampling frequency. In other words, it looks like the temperature sensor can be read too fast (with or without oversampling) to give incorrect temperature readings. ...

I am developing a BLE product using the stm32wb and have it working as a peripheral/server. I need to add the ability to work as a central also and am following the BLE_p2pRouteur example in STM32CubeWB/Projects/P-NUCLEO-WB55.Nucleo/Applications/BLE...

When running your PWR_ModeSelection example on a NUCLEO-L496ZG board the current consumption in run range 2, 24MHz depends on the order objects are linked in the executable. When the object_list is in this order:hal/stm32l4xx_hal.ohal/stm32l4xx_hal_...

Ideally using something like the HCI_RESET command is preferable for our application rather than simply cycling power or resetting the system. Is there some procedure for recycling the M0 processor in the stm32wb while leaving the application proce...

Apparently, the BLE stack doesn't implement security level 3 encryption, only level 4 encryption? Who knows? Anyway, setting MITM_Mode=1, SC_Support=2, and Use_Fixed_Pin=1 (do not used a fixed pin) in aci_gap_set_authentication_requirement() gets yo...

I guess I need to add that I very much want to be able to say that the product in development conforms to the NIST bluetooth security recommendations. I find the documentation on BLE security for the STM32WB pretty opaque in terms of getting clear ...

This is my error, I apologize for posting. After going the the example again, there are three calls made to get the handles needed to connect and set notifications:1) aci_gatt_disc_all_primary_services() responds through ACI_ATT_READ_BY_GROUP_TYPE...

Any update on this?

User1655833706281357277 · 2023-05-05

Last reply, I promise. In both cases the power measurement is done with the debug pod disconnected from the nucleo board. The serial port is left attached in both runs.

Does the STM32WB BLE stack implement Security Level 4 (Elliptic Curve Diffie-Hellman Encryption)?

Internal temperature sensor maximum sample rate specification for the stm32l4 series?

stm32wb55 returns "unlikely error" when enabling notifications on a peripheral characteristic

NUCLEO 144 board power consumption depends on the link order of the compiled objects in your STM32CubeL4/Projects/NUCLEO-L496ZG/Examples/PWR/PWR_ModesSelection example

We have a product using the stm32wb55 that can be exposed to strong electromagnetic files. We occasionally see the HCI_HARDWARE_ERROR_EVENT (time overrun) error from the radio and lose the BLE link. Is there a way to restart the radio when this happens?
