Resolved! LPM Mode does not run the radio
I have succesfully implemented my own BLE advertisement (LEGACY) using the STM32WB55 MCU.I have attached my code below.In a nutshell I have created three timers and two tasks.When the Heartbeat timer expires it calls the Heartbeat function:This then ...
Resolved! aci_gatt_update_char_value_ext issue
Hello,We are trying to use MTU larger than 24X bytes.The characteristic size set to 483 bytes (CFG_BLE_MAX_ATT_MTU).We tried to use aci_gatt_update_char_value_ext to set the value (as the HCI layer is limited to 255 bytes transfer).aci_gatt_update_ch...
Low Power Mode in STM32WB

How can i fix "Could not determine GDB version using command: " error ?
Hello,I am trying to use B-L072Z-LRWAN1 kit with library from Semtech which is Firmware Driver and LoRaWAN Stack V4.1.0. I solved error step by step with adding files one by one. Now that error occurs after Debug program. I am using Ubuntu Disco Ding...
HeartRate with FreeRTOS
Hi Madam/Sir,I'd like to ask for help regarding creating a new Project replicating the HeartrateFreeRTOS example. When I load my custom board with the HeartRateFreeRTOS example, I'm able to connect with ST's BLE toolbox and see all the data incoming....
Resolved! Does the STM32WB BLE stack implement Security Level 4 (Elliptic Curve Diffie-Hellman Encryption)?
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...
STM32WB10 BLE advertising not visible on other devices
Hello,I have a custom PCB with STM32WB10 with full BLE stack configured with server profile and a custom template in Cube IDE. The problem is that other devices don't see its advertising packets (or maybe are ignoring them), I tried BlueSee on a Macb...
stm32wb55 SHCI_C2_SetSystemClock() causes hardfault
I find that when entering deep sleep using aci_gap_set_non_discoverable(), C2 would not reliably enter the ultra low (~4uA) power consumption mode, current would jump to ~5mA. a) Calling aci_gap_set_non_discoverable() while there is RF activity can ...
