STM32WB BLE configuration / sizing (BLE_MBLOCK_COUNT)
Ok, a tricky one. So for services and attributes it's documented that there is 10752 bytes, each service takes up 48 bytes, each attribute 40 bytes, and if you got th number of services and attributes you can compute backwards BLE_ATT_VALUE_ARRAY_S...
Resolved! BLE fails on cold boot, but works perfectly after entering FUS mode.
Hi everyone,I am experiencing a very specific initialization issue with a custom board based on the STM32WB55RGV6.We recently manufactured a batch of 30 boards. 22 of them are working flawlessly, but 8 boards fail to start the BLE radio on a cold boo...
STM32WL33 Deepstop power consumption higher than normal
We have a custom `STM32WL33CCV6` (`VFQFPN32`) board that should reach about `4 µA` in Deepstop, similar to the NUCLEO-WL33, but instead it drops only to roughly `450–500 µA` and appears to restart on Deepstop entry. `NRST` does not glitch low, and th...
STM32WB55 Custom board programming issue
Hello,I have designed a custom board with stm32wb55. I used the reference schematic and checked everything but I cannot program the board from my cubeide. I have tried different configuration settings in Cube IDE but always got "No device on target" ...

STM32WBA BLE Direction Finding with Low Power
Hello,I am currently working with the STM32WBA65RI for BLE Direction Finding using connectionless mode. I would like to know if it is possible to use a low-power mode such as Standby with RTC, allowing the board to consume only a few nanoamps, then w...
keys and context saving in LoRaWAN V1.5.0 LBM
I am struggling with the keys in the new V1.5.0 LBM stack. Keys are read from NFC EEPROM and device is joining. After joining, I expect the stack to save the join and session keys in secure memory so the keys are deleted in EEPROM for security. After...
