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...

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" ...

UART of NUCLEO-WB09KE UART signal no found

Dear ST team. I am testing UART of NUCLEO-WB09KE with the board [STM32WB09 Nucleo-64 board (MB1801 and MB2032)] I Set UART1 PIN PB4, PB4 with the source attached[100ms period tx send ]. I am checking CN3(23), CN4(35) but no signal shown. Is there a...

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...

Stop mode on Threadx with BLE on WBA

Hello. I'm working on a BLE application that uses an STM WBA55 board and ThreadX. It was based on the St Threadx p2pServer example, The Sequencer is disabled. I'm using stmCubeIDE 1.19 and st_fw1.7 and i cannot migrate to new versions due to compati...

STM32WL33 DMR Signal Rx RSSI and Demodulation

Dear Sir or Madam, We would like to use NUCLEO-WL33CC2 to verify DMR RSSI reliable detection(compulsory requirement) and demodulation(optional requirement). We only need rx chain for scanning purpose. As per ETSI TS 102 361-1, DMR TDMA frame has s...
